If `needs_update` is not `true`, stop without creating a PR. Otherwise use `latest_tag`. + + - If the input is explicit, use it directly. + +3. Compute update metadata without changing files: + + ```bash + python3 ci/update_lance_dependency.py "$TAG_OR_VERSION" --metadata-only + ``` + + Before making changes, check for an existing open PR with the emitted `pr_title`: + + ```bash + gh pr list --search "\"$PR_TITLE\" in:title" --state open --limit 1 --json number,url,title + ``` + + If a matching open PR exists, stop and report it instead of creating a duplicate. + +4. Run the deterministic update entrypoint: + + ```bash + python3 ci/update_lance_dependency.py "$TAG_OR_VERSION" + ``` + + This updates the Rust workspace Lance dependencies through `ci/set_lance_version.py`, updates `java/pom.xml`, refreshes Cargo metadata, and prints JSON metadata containing `branch_name`, `commit_message`, and `pr_title`. + +5.

If the task asks to publish the update, create a branch using the printed `branch_name`, stage all relevant files, and commit using the printed `commit_message`.

Do not force-push. + +10. Create a PR targeting `main` with the printed `pr_title`. If there is no PR template, keep the body to two or three concise sentences: state the Lance dependency bump, note any required compatibility fixes, and link the triggering Lance tag or release. + +11. Read back the remote PR title after creation. If it is not a Conventional Commit title, fix it immediately. + +12. When running in GitHub Actions after creating the LanceDB PR, trigger the Sophon dependency update: + + ```bash + gh workflow run codex-bump-lancedb-lance.yml \ + --repo lancedb/sophon \ + -f lance_ref="$LANCE_TAG" \ + -f lancedb_ref="$BRANCH_NAME" + gh run list --repo lancedb/sophon --workflow codex-bump-lancedb-lance.yml --limit 1 --json databaseId,url,displayTitle + ``` + + Use the emitted metadata `tag` value as `LANCE_TAG`. Do this only after a new LanceDB PR has been created. If the update was skipped because no update is needed or an open PR already exists, do not trigger Sophon. + +## GitHub Actions + +When this skill is used from GitHub Actions, `TAG`, `GH_TOKEN`, and `GITHUB_TOKEN` may already be set. Resolve `latest` first when `TAG` is empty. Once an explicit tag or version is known, use: + +```bash +python3 ci/update_lance_dependency.py "$TAG" --github-output "$GITHUB_OUTPUT" +``` + +Then use the emitted `branch_name`, `commit_message`, and `pr_title` values for branch, commit, and PR creation. diff --git a/.bumpversion.toml b/.bumpversion.toml index ec9fff33d..0909579cb 100644 --- a/.bumpversion.toml +++ b/.bumpversion.toml @@ -1,5 +1,5 @@ [tool.bumpversion] -current_version = "0.21.4-beta.1" +current_version = "0.41.0-beta.13" parse = """(?x) (?P0|[1-9]\\d*)\\.

To check your work: + +```shell +pip install -r docs/requirements.txt +cd docs && PYTHONPATH=. mkdocs build +``` + +The docs site only builds on pushes to `main`, so this is not covered by PR CI. + +## Review Guidelines + +Please consider the following when reviewing code contributions. + +### Rust API design +* Design public APIs so they can be evolved easily in the future without breaking + changes. Often this means using builder patterns or options structs instead of + long argument lists. +* For public APIs, prefer inputs that use `Into` or `AsRef` traits to allow + more flexible inputs. For example, use `name: Into` instead of `name: String`, + so we don't have to write `func("my_string".to_string())`. + +### Testing +* Ensure all new public APIs have documentation and examples. +* Ensure that all bugfixes and features have corresponding tests. **We do not merge + code without tests.** + +### Documentation +* New features must include updates to the rust documentation comments.

These examples are not yet wired into +pull-request CI; that integration remains follow-up work. + +**Every heading carries an explicit `{#anchor}`.** Those anchors are how the +Enterprise pages attach their additions to the right section, so they are +assigned once and never regenerated. Leave an existing anchor alone even when +you reword the heading above it; only new headings need a new one. + +**A page can declare where it applies.** Its frontmatter says whether LanceDB +OSS and LanceDB Enterprise support the feature: use only `available` or +`unavailable`, and one sentence that explains its scope. Availability describes +product support, not whether a particular deployment has enabled or configured +the feature. A supported feature stays `available` when it requires setup, a +supported SDK or server version, or has differences between offerings. State +those requirements in the summary or the relevant section, including unsupported +subfeatures. Do not use `varies`, infer support from an unknown status, or mark an +absent capability available. Narrow a page to the capability it actually covers +when necessary. For example: + +```yaml +availability: + oss: unavailable + enterprise: available + summary: >- + Requests to a deployment carry an API key or an OAuth token. Embedded + LanceDB has no server to sign in to. +``` + +The assembled site renders this as a label above the page's content and as a +sidebar tag when only one offering has the feature. Do not also open the page +with a badge of its own, and keep a qualification that only one section needs +in that section's text. A `mint dev` preview of `docs/web` alone renders +neither the labels nor the tags. + +**A feature can be documented before its release.** List a draft page in +`docs/web/.mintignore`, keep it out of the navigation in `docs.json`, and do not +link to it from published pages. Wrap a draft section in an MDX comment, +`{/* ... */}`, whose first line names the release, such as +`Draft for the Feature X release.` Keep draft table rows and list items in a +comment below the table or list, since a comment between rows or items breaks +it. Drafts are hidden from readers but stay in the source, and availability does +not change what is published. At release, remove the comments and the +`.mintignore` entries, and restore the navigation and links.

    +   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
    +
    +   1. Definitions.
    +
    +      "License" shall mean the terms and conditions for use, reproduction,

    +      direction or management of such entity, whether by contract or
    +      otherwise, or (ii) ownership of fifty percent (50%) or more of the

    +      transformation or translation of a Source form, including but

    +
    +      "Work" shall mean the work of authorship, whether in Source or
    +      Object form, made available under the License, as indicated by a
    +      copyright notice that is included in or attached to the work
    +      (an example is provided in the Appendix below).
    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications
    +      represent, as a whole, an original work of authorship. For the purposes
    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including
    +      the original version of the Work and any modifications or additions

    +      submitted to Licensor for inclusion in the Work by the copyright owner
    +      or by an individual or Legal Entity authorized to submit on behalf of
    +      the copyright owner. For the purposes of this definition, "submitted"
    +      means any form of electronic, verbal, or written communication sent
    +      to the Licensor or its representatives, including but not limited to

    +
    +      "Contributor" shall mean Licensor and any individual or Legal Entity
    +      on behalf of whom a Contribution has been received by Licensor and
    +      subsequently incorporated within the Work.
    +
    +   2. Grant of Copyright License. Subject to the terms and conditions of
    +      this License, each Contributor hereby grants to You a perpetual,
    +      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
    +      copyright license to reproduce, prepare Derivative Works of,
    +      publicly display, publicly perform, sublicense, and distribute the
    +      Work and such Derivative Works in Source or Object form.
    +
    +   3. Grant of Patent License. Subject to the terms and conditions of

    +      (except as stated in this section) patent license to make, have made,
    +      use, offer to sell, sell, import, and otherwise transfer the Work,
    +      where such license applies only to those patent claims licensable
    +      by such Contributor that are necessarily infringed by their
    +      Contribution(s) alone or by combination of their Contribution(s)
    +      with the Work to which such Contribution(s) was submitted. If You
    +      institute patent litigation against any entity (including a
    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate
    +      as of the date such litigation is filed.
    +
    +   4. Redistribution. You may reproduce and distribute copies of the
    +      Work or Derivative Works thereof in any medium, with or without
    +      modifications, and in Source or Object form, provided that You
    +      meet the following conditions:
    +
    +      (a) You must give any other recipients of the Work or
    +          Derivative Works a copy of this License; and
    +
    +      (b) You must cause any modified files to carry prominent notices
    +          stating that You changed the files; and
    +
    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.
    +

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications
    +      represent, as a whole, an original work of authorship. For the purposes
    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including
    +      the original version of the Work and any modifications or additions

    +      the copyright owner. For the purposes of this definition, "submitted"
    +      means any form of electronic, verbal, or written communication sent

    +      copyright license to reproduce, prepare Derivative Works of,
    +      publicly display, publicly perform, sublicense, and distribute the
    +      Work and such Derivative Works in Source or Object form.
    +
    +   3. Grant of Patent License. Subject to the terms and conditions of

    +      (except as stated in this section) patent license to make, have made,
    +      use, offer to sell, sell, import, and otherwise transfer the Work,
    +      where such license applies only to those patent claims licensable
    +      by such Contributor that are necessarily infringed by their
    +      Contribution(s) alone or by combination of their Contribution(s)
    +      with the Work to which such Contribution(s) was submitted. If You
    +      institute patent litigation against any entity (including a
    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate
    +      as of the date such litigation is filed.
    +
    +   4. Redistribution. You may reproduce and distribute copies of the
    +      Work or Derivative Works thereof in any medium, with or without
    +      modifications, and in Source or Object form, provided that You

    +
    +      (a) You must give any other recipients of the Work or
    +          Derivative Works a copy of this License; and
    +
    +      (b) You must cause any modified files to carry prominent notices
    +          stating that You changed the files; and
    +
    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.
    +
    +   END OF TERMS AND CONDITIONS

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications
    +      represent, as a whole, an original work of authorship. For the purposes
    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including
    +      the original version of the Work and any modifications or additions

    +      means any form of electronic, verbal, or written communication sent

    +      (except as stated in this section) patent license to make, have made,
    +      use, offer to sell, sell, import, and otherwise transfer the Work,
    +      where such license applies only to those patent claims licensable
    +      by such Contributor that are necessarily infringed by their
    +      Contribution(s) alone or by combination of their Contribution(s)
    +      with the Work to which such Contribution(s) was submitted. If You
    +      institute patent litigation against any entity (including a
    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate
    +      as of the date such litigation is filed.
    +
    +   4. Redistribution. You may reproduce and distribute copies of the
    +      Work or Derivative Works thereof in any medium, with or without
    +      modifications, and in Source or Object form, provided that You

    +
    +      (a) You must give any other recipients of the Work or
    +          Derivative Works a copy of this License; and
    +
    +      (b) You must cause any modified files to carry prominent notices
    +          stating that You changed the files; and
    +
    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.
    +

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications

    +      of this License, Derivative Works shall not include works that remain

    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +      Contribution(s) alone or by combination of their Contribution(s)
    +      with the Work to which such Contribution(s) was submitted. If You
    +      institute patent litigation against any entity (including a
    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate
    +      as of the date such litigation is filed.
    +
    +   4. Redistribution. You may reproduce and distribute copies of the

    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications
    +      represent, as a whole, an original work of authorship. For the purposes
    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses

    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the

    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing

    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications
    +      represent, as a whole, an original work of authorship. For the purposes
    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including
    +      the original version of the Work and any modifications or additions

    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate

    +
    +   4. Redistribution. You may reproduce and distribute copies of the

    +
    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications

    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses

    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or

    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this

    +
    +   6. Trademarks. This License does not grant permission to use the trade

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications

    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses

    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and

    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside

    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify

    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or

    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions

    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.

    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,

    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade

    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the

    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the

    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must

    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or

    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify

    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or

    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be

    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,

    +      by You to the Licensor shall be under the terms and conditions of

    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,

    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or

    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the

    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications

    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one

    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or

    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify

    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or

    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained

    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed

    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications

    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must

    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or

    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of

    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or

    +      (c) You must retain, in the Source form of any Derivative Works

    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained

    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,

    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or

    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the

    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications

    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including
    +      the original version of the Work and any modifications or additions

    +      or a Contribution incorporated within the Work constitutes direct

    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained

    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or

    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of

    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or

    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions

    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade

    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.

    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +   "Derivative Works" shall mean any work, whether in Source or Object
    +   form, that is based on (or derived from) the Work and for which the

    +   Object form, made available under the License, as indicated by a
    +   copyright notice that is included in or attached to the work

    +
    +   "Derivative Works" shall mean any work, whether in Source or Object
    +   form, that is based on (or derived from) the Work and for which the
    +   editorial revisions, annotations, elaborations, or other modifications
    +   represent, as a whole, an original work of authorship. For the purposes
    +   of this License, Derivative Works shall not include works that remain

    +   by such Contributor that are necessarily infringed by their
    +   Contribution(s) alone or by combination of their Contribution(s)
    +   with the Work to which such Contribution(s) was submitted. If You
    +   institute patent litigation against any entity (including a
    +   cross-claim or counterclaim in a lawsuit) alleging that the Work
    +   or a Contribution incorporated within the Work constitutes direct
    +   or contributory patent infringement, then any patent licenses
    +   granted to You under this License for that Work shall terminate
    +   as of the date such litigation is filed.
    +
    +4. Redistribution. You may reproduce and distribute copies of the
    +   Work or Derivative Works thereof in any medium, with or without
    +   modifications, and in Source or Object form, provided that You

    +       attribution notices from the Source form of the Work,
    +       excluding those notices that do not pertain to any part of
    +       the Derivative Works; and
    +
    +   (d) If the Work includes a "NOTICE" text file as part of its
    +       distribution, then any Derivative Works that You distribute must
    +       include a readable copy of the attribution notices contained
    +       within such NOTICE file, excluding those notices that do not
    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed
    +       as part of the Derivative Works; within the Source form or
    +       documentation, if provided along with the Derivative Works; or,
    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents
    +       of the NOTICE file are for informational purposes only and

    +       notices within Derivative Works that You distribute, alongside
    +       or as an addendum to the NOTICE text from the Work, provided
    +       that such additional attribution notices cannot be construed
    +       as modifying the License.
    +
    +   You may add Your own copyright statement to Your modifications and
    +   may provide additional or different license terms and conditions
    +   for use, reproduction, or distribution of Your modifications, or

    +   reproduction, and distribution of the Work otherwise complies with
    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.
    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each
    +   Contributor provides its Contributions) on an "AS IS" BASIS,
    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions
    +   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +
    +8. Limitation of Liability. In no event and under no legal theory,
    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +

    +   source, and configuration files.
    +
    +   "Object" form shall mean any form resulting from mechanical
    +   transformation or translation of a Source form, including but
    +   not limited to compiled object code, generated documentation,

    +
    +   "Work" shall mean the work of authorship, whether in Source or
    +   Object form, made available under the License, as indicated by a
    +   copyright notice that is included in or attached to the work
    +   (an example is provided in the Appendix below).
    +
    +   "Derivative Works" shall mean any work, whether in Source or Object
    +   form, that is based on (or derived from) the Work and for which the
    +   editorial revisions, annotations, elaborations, or other modifications
    +   represent, as a whole, an original work of authorship. For the purposes
    +   of this License, Derivative Works shall not include works that remain
    +   separable from, or merely link (or bind by name) to the interfaces of,
    +   the Work and Derivative Works thereof.
    +
    +   "Contribution" shall mean any work of authorship, including
    +   the original version of the Work and any modifications or additions

    +   Licensor for the purpose of discussing and improving the Work, but

    +   this License, each Contributor hereby grants to You a perpetual,
    +   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
    +   copyright license to reproduce, prepare Derivative Works of,
    +   publicly display, publicly perform, sublicense, and distribute the

    +
    +3. Grant of Patent License. Subject to the terms and conditions of
    +   this License, each Contributor hereby grants to You a perpetual,

    +   by such Contributor that are necessarily infringed by their
    +   Contribution(s) alone or by combination of their Contribution(s)
    +   with the Work to which such Contribution(s) was submitted. If You
    +   institute patent litigation against any entity (including a
    +   cross-claim or counterclaim in a lawsuit) alleging that the Work
    +   or a Contribution incorporated within the Work constitutes direct
    +   or contributory patent infringement, then any patent licenses
    +   granted to You under this License for that Work shall terminate
    +   as of the date such litigation is filed.
    +
    +4. Redistribution. You may reproduce and distribute copies of the
    +   Work or Derivative Works thereof in any medium, with or without
    +   modifications, and in Source or Object form, provided that You
    +   meet the following conditions:
    +
    +   (a) You must give any other recipients of the Work or
    +       Derivative Works a copy of this License; and

    +       stating that You changed the files; and
    +
    +   (c) You must retain, in the Source form of any Derivative Works
    +       that You distribute, all copyright, patent, trademark, and
    +       attribution notices from the Source form of the Work,
    +       excluding those notices that do not pertain to any part of
    +       the Derivative Works; and
    +
    +   (d) If the Work includes a "NOTICE" text file as part of its
    +       distribution, then any Derivative Works that You distribute must
    +       include a readable copy of the attribution notices contained
    +       within such NOTICE file, excluding those notices that do not
    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed
    +       as part of the Derivative Works; within the Source form or
    +       documentation, if provided along with the Derivative Works; or,
    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents
    +       of the NOTICE file are for informational purposes only and
    +       do not modify the License. You may add Your own attribution
    +       notices within Derivative Works that You distribute, alongside
    +       or as an addendum to the NOTICE text from the Work, provided
    +       that such additional attribution notices cannot be construed
    +       as modifying the License.
    +
    +   You may add Your own copyright statement to Your modifications and
    +   may provide additional or different license terms and conditions
    +   for use, reproduction, or distribution of Your modifications, or
    +   for any such Derivative Works as a whole, provided Your use,
    +   reproduction, and distribution of the Work otherwise complies with
    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.
    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each
    +   Contributor provides its Contributions) on an "AS IS" BASIS,
    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions
    +   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +
    +8. Limitation of Liability. In no event and under no legal theory,
    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +       attribution notices from the Source form of the Work,
    +       excluding those notices that do not pertain to any part of
    +       the Derivative Works; and
    +
    +   (d) If the Work includes a "NOTICE" text file as part of its
    +       distribution, then any Derivative Works that You distribute must
    +       include a readable copy of the attribution notices contained

    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents
    +       of the NOTICE file are for informational purposes only and

    +       notices within Derivative Works that You distribute, alongside
    +       or as an addendum to the NOTICE text from the Work, provided
    +       that such additional attribution notices cannot be construed
    +       as modifying the License.
    +
    +   You may add Your own copyright statement to Your modifications and
    +   may provide additional or different license terms and conditions

    +   for any such Derivative Works as a whole, provided Your use,
    +   reproduction, and distribution of the Work otherwise complies with
    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.
    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each
    +   Contributor provides its Contributions) on an "AS IS" BASIS,
    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions

    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +
    +8. Limitation of Liability. In no event and under no legal theory,
    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +
    +   (c) You must retain, in the Source form of any Derivative Works

    +       of the following places: within a NOTICE text file distributed
    +       as part of the Derivative Works; within the Source form or
    +       documentation, if provided along with the Derivative Works; or,
    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents
    +       of the NOTICE file are for informational purposes only and

    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work

    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each

    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions
    +   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +
    +8. Limitation of Liability. In no event and under no legal theory,
    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +
    +   "Derivative Works" shall mean any work, whether in Source or Object
    +   form, that is based on (or derived from) the Work and for which the

    +
    +   "Derivative Works" shall mean any work, whether in Source or Object
    +   form, that is based on (or derived from) the Work and for which the
    +   editorial revisions, annotations, elaborations, or other modifications
    +   represent, as a whole, an original work of authorship. For the purposes
    +   of this License, Derivative Works shall not include works that remain

    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed

    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work

    +   transformation or translation of a Source form, including but

    +   Object form, made available under the License, as indicated by a
    +   copyright notice that is included in or attached to the work

    +
    +   "Derivative Works" shall mean any work, whether in Source or Object
    +   form, that is based on (or derived from) the Work and for which the
    +   editorial revisions, annotations, elaborations, or other modifications
    +   represent, as a whole, an original work of authorship. For the purposes
    +   of this License, Derivative Works shall not include works that remain
    +   separable from, or merely link (or bind by name) to the interfaces of,
    +   the Work and Derivative Works thereof.

    +   by such Contributor that are necessarily infringed by their
    +   Contribution(s) alone or by combination of their Contribution(s)
    +   with the Work to which such Contribution(s) was submitted. If You
    +   institute patent litigation against any entity (including a
    +   cross-claim or counterclaim in a lawsuit) alleging that the Work
    +   or a Contribution incorporated within the Work constitutes direct
    +   or contributory patent infringement, then any patent licenses
    +   granted to You under this License for that Work shall terminate
    +   as of the date such litigation is filed.
    +
    +4. Redistribution. You may reproduce and distribute copies of the
    +   Work or Derivative Works thereof in any medium, with or without
    +   modifications, and in Source or Object form, provided that You
    +   meet the following conditions:

    +       attribution notices from the Source form of the Work,
    +       excluding those notices that do not pertain to any part of
    +       the Derivative Works; and
    +
    +   (d) If the Work includes a "NOTICE" text file as part of its
    +       distribution, then any Derivative Works that You distribute must
    +       include a readable copy of the attribution notices contained
    +       within such NOTICE file, excluding those notices that do not
    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed
    +       as part of the Derivative Works; within the Source form or
    +       documentation, if provided along with the Derivative Works; or,
    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents
    +       of the NOTICE file are for informational purposes only and
    +       do not modify the License. You may add Your own attribution
    +       notices within Derivative Works that You distribute, alongside
    +       or as an addendum to the NOTICE text from the Work, provided
    +       that such additional attribution notices cannot be construed
    +       as modifying the License.
    +
    +   You may add Your own copyright statement to Your modifications and
    +   may provide additional or different license terms and conditions
    +   for use, reproduction, or distribution of Your modifications, or
    +   for any such Derivative Works as a whole, provided Your use,
    +   reproduction, and distribution of the Work otherwise complies with
    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.
    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each
    +   Contributor provides its Contributions) on an "AS IS" BASIS,
    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions
    +   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +
    +8. Limitation of Liability. In no event and under no legal theory,
    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +       notices within Derivative Works that You distribute, alongside
    +       or as an addendum to the NOTICE text from the Work, provided
    +       that such additional attribution notices cannot be construed

    +   reproduction, and distribution of the Work otherwise complies with
    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.

    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,

    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +
    +8. Limitation of Liability. In no event and under no legal theory,
    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +   by such Contributor that are necessarily infringed by their
    +   Contribution(s) alone or by combination of their Contribution(s)
    +   with the Work to which such Contribution(s) was submitted. If You
    +   institute patent litigation against any entity (including a
    +   cross-claim or counterclaim in a lawsuit) alleging that the Work
    +   or a Contribution incorporated within the Work constitutes direct
    +   or contributory patent infringement, then any patent licenses
    +   granted to You under this License for that Work shall terminate
    +   as of the date such litigation is filed.
    +
    +4. Redistribution. You may reproduce and distribute copies of the

    +       that You distribute, all copyright, patent, trademark, and
    +       attribution notices from the Source form of the Work,
    +       excluding those notices that do not pertain to any part of
    +       the Derivative Works; and
    +
    +   (d) If the Work includes a "NOTICE" text file as part of its
    +       distribution, then any Derivative Works that You distribute must
    +       include a readable copy of the attribution notices contained
    +       within such NOTICE file, excluding those notices that do not
    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed
    +       as part of the Derivative Works; within the Source form or
    +       documentation, if provided along with the Derivative Works; or,
    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents
    +       of the NOTICE file are for informational purposes only and

    +       notices within Derivative Works that You distribute, alongside
    +       or as an addendum to the NOTICE text from the Work, provided
    +       that such additional attribution notices cannot be construed
    +       as modifying the License.
    +
    +   You may add Your own copyright statement to Your modifications and
    +   may provide additional or different license terms and conditions
    +   for use, reproduction, or distribution of Your modifications, or
    +   for any such Derivative Works as a whole, provided Your use,
    +   reproduction, and distribution of the Work otherwise complies with
    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.
    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each
    +   Contributor provides its Contributions) on an "AS IS" BASIS,
    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions
    +   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +

    +   whether in tort (including negligence), contract, or otherwise,

    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +
    +   "Derivative Works" shall mean any work, whether in Source or Object
    +   form, that is based on (or derived from) the Work and for which the
    +   editorial revisions, annotations, elaborations, or other modifications
    +   represent, as a whole, an original work of authorship. For the purposes
    +   of this License, Derivative Works shall not include works that remain

    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed

    +      form, that is based on (or derived from) the Work and for which the

    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate

    +   4. Redistribution. You may reproduce and distribute copies of the

    +
    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or

    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing

    +
    +1. Definitions.

    +
    +   "Source" form shall mean the preferred form for making modifications,

    +   source, and configuration files.
    +
    +   "Object" form shall mean any form resulting from mechanical
    +   transformation or translation of a Source form, including but
    +   not limited to compiled object code, generated documentation,
    +   and conversions to other media types.
    +
    +   "Work" shall mean the work of authorship, whether in Source or
    +   Object form, made available under the License, as indicated by a
    +   copyright notice that is included in or attached to the work
    +   (an example is provided in the Appendix below).
    +
    +   "Derivative Works" shall mean any work, whether in Source or Object
    +   form, that is based on (or derived from) the Work and for which the
    +   editorial revisions, annotations, elaborations, or other modifications
    +   represent, as a whole, an original work of authorship. For the purposes
    +   of this License, Derivative Works shall not include works that remain
    +   separable from, or merely link (or bind by name) to the interfaces of,
    +   the Work and Derivative Works thereof.
    +
    +   "Contribution" shall mean any work of authorship, including
    +   the original version of the Work and any modifications or additions
    +   to that Work or Derivative Works thereof, that is intentionally
    +   submitted to Licensor for inclusion in the Work by the copyright owner
    +   or by an individual or Legal Entity authorized to submit on behalf of
    +   the copyright owner. For the purposes of this definition, "submitted"
    +   means any form of electronic, verbal, or written communication sent
    +   to the Licensor or its representatives, including but not limited to
    +   communication on electronic mailing lists, source code control systems,
    +   and issue tracking systems that are managed by, or on behalf of, the
    +   Licensor for the purpose of discussing and improving the Work, but
    +   excluding communication that is conspicuously marked or otherwise
    +   designated in writing by the copyright owner as "Not a Contribution."
    +
    +   "Contributor" shall mean Licensor and any individual or Legal Entity
    +   on behalf of whom a Contribution has been received by Licensor and
    +   subsequently incorporated within the Work.
    +
    +2. Grant of Copyright License. Subject to the terms and conditions of
    +   this License, each Contributor hereby grants to You a perpetual,
    +   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
    +   copyright license to reproduce, prepare Derivative Works of,
    +   publicly display, publicly perform, sublicense, and distribute the
    +   Work and such Derivative Works in Source or Object form.
    +
    +3. Grant of Patent License. Subject to the terms and conditions of
    +   this License, each Contributor hereby grants to You a perpetual,
    +   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
    +   (except as stated in this section) patent license to make, have made,
    +   use, offer to sell, sell, import, and otherwise transfer the Work,
    +   where such license applies only to those patent claims licensable
    +   by such Contributor that are necessarily infringed by their
    +   Contribution(s) alone or by combination of their Contribution(s)
    +   with the Work to which such Contribution(s) was submitted. If You
    +   institute patent litigation against any entity (including a
    +   cross-claim or counterclaim in a lawsuit) alleging that the Work
    +   or a Contribution incorporated within the Work constitutes direct
    +   or contributory patent infringement, then any patent licenses
    +   granted to You under this License for that Work shall terminate
    +   as of the date such litigation is filed.
    +
    +4. Redistribution. You may reproduce and distribute copies of the
    +   Work or Derivative Works thereof in any medium, with or without
    +   modifications, and in Source or Object form, provided that You
    +   meet the following conditions:
    +
    +   (a) You must give any other recipients of the Work or
    +       Derivative Works a copy of this License; and
    +
    +   (b) You must cause any modified files to carry prominent notices
    +       stating that You changed the files; and
    +
    +   (c) You must retain, in the Source form of any Derivative Works
    +       that You distribute, all copyright, patent, trademark, and
    +       attribution notices from the Source form of the Work,
    +       excluding those notices that do not pertain to any part of
    +       the Derivative Works; and
    +
    +   (d) If the Work includes a "NOTICE" text file as part of its
    +       distribution, then any Derivative Works that You distribute must
    +       include a readable copy of the attribution notices contained
    +       within such NOTICE file, excluding those notices that do not
    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed
    +       as part of the Derivative Works; within the Source form or
    +       documentation, if provided along with the Derivative Works; or,
    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents
    +       of the NOTICE file are for informational purposes only and
    +       do not modify the License. You may add Your own attribution
    +       notices within Derivative Works that You distribute, alongside
    +       or as an addendum to the NOTICE text from the Work, provided
    +       that such additional attribution notices cannot be construed
    +       as modifying the License.
    +
    +   You may add Your own copyright statement to Your modifications and
    +   may provide additional or different license terms and conditions
    +   for use, reproduction, or distribution of Your modifications, or
    +   for any such Derivative Works as a whole, provided Your use,
    +   reproduction, and distribution of the Work otherwise complies with
    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.
    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each
    +   Contributor provides its Contributions) on an "AS IS" BASIS,
    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions
    +   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +
    +8. Limitation of Liability. In no event and under no legal theory,
    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +
    +CC0 1.0 Universal
    +
    +    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
    +    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
    +    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
    +    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
    +    REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
    +    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
    +    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
    +    HEREUNDER.
    +
    +Statement of Purpose
    +
    +The laws of most jurisdictions throughout the world automatically confer
    +exclusive Copyright and Related Rights (defined below) upon the creator
    +and subsequent owner(s) (each and all, an "owner") of an original work of
    +authorship and/or a database (each, a "Work").
    +
    +Certain owners wish to permanently relinquish those rights to a Work for
    +the purpose of contributing to a commons of creative, cultural and
    +scientific works ("Commons") that the public can reliably and without fear
    +of later claims of infringement build upon, modify, incorporate in other
    +works, reuse and redistribute as freely as possible in any form whatsoever
    +and for any purposes, including without limitation commercial purposes.
    +These owners may contribute to the Commons to promote the ideal of a free
    +culture and the further production of creative, cultural and scientific
    +works, or to gain reputation or greater distribution for their Work in
    +part through the use and efforts of others.
    +
    +For these and/or other purposes and motivations, and without any
    +expectation of additional consideration or compensation, the person
    +associating CC0 with a Work (the "Affirmer"), to the extent that he or she
    +is an owner of Copyright and Related Rights in the Work, voluntarily
    +elects to apply CC0 to the Work and publicly distribute the Work under its
    +terms, with knowledge of his or her Copyright and Related Rights in the
    +Work and the meaning and intended legal effect of CC0 on those rights.
    +
    +1. Copyright and Related Rights. A Work made available under CC0 may be
    +protected by copyright and related or neighboring rights ("Copyright and
    +Related Rights"). Copyright and Related Rights include, but are not
    +limited to, the following:
    +
    +  i. the right to reproduce, adapt, distribute, perform, display,
    +     communicate, and translate a Work;
    + ii. moral rights retained by the original author(s) and/or performer(s);
    +iii. publicity and privacy rights pertaining to a person's image or
    +     likeness depicted in a Work;
    + iv. rights protecting against unfair competition in regards to a Work,
    +     subject to the limitations in paragraph 4(a), below;
    +  v. rights protecting the extraction, dissemination, use and reuse of data
    +     in a Work;
    + vi. database rights (such as those arising under Directive 96/9/EC of the
    +     European Parliament and of the Council of 11 March 1996 on the legal
    +     protection of databases, and under any national implementation
    +     thereof, including any amended or successor version of such
    +     directive); and
    +vii. other similar, equivalent or corresponding rights throughout the
    +     world based on applicable law or treaty, and any national
    +     implementations thereof.
    +
    +2. Waiver. To the greatest extent permitted by, but not in contravention
    +of, applicable law, Affirmer hereby overtly, fully, permanently,
    +irrevocably and unconditionally waives, abandons, and surrenders all of
    +Affirmer's Copyright and Related Rights and associated claims and causes
    +of action, whether now known or unknown (including existing as well as
    +future claims and causes of action), in the Work (i) in all territories
    +worldwide, (ii) for the maximum duration provided by applicable law or
    +treaty (including future time extensions), (iii) in any current or future
    +medium and for any number of copies, and (iv) for any purpose whatsoever,
    +including without limitation commercial, advertising or promotional
    +purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
    +member of the public at large and to the detriment of Affirmer's heirs and
    +successors, fully intending that such Waiver shall not be subject to
    +revocation, rescission, cancellation, termination, or any other legal or
    +equitable action to disrupt the quiet enjoyment of the Work by the public
    +as contemplated by Affirmer's express Statement of Purpose.
    +
    +3. Public License Fallback. Should any part of the Waiver for any reason
    +be judged legally invalid or ineffective under applicable law, then the
    +Waiver shall be preserved to the maximum extent permitted taking into
    +account Affirmer's express Statement of Purpose. In addition, to the
    +extent the Waiver is so judged Affirmer hereby grants to each affected
    +person a royalty-free, non transferable, non sublicensable, non exclusive,
    +irrevocable and unconditional license to exercise Affirmer's Copyright and
    +Related Rights in the Work (i) in all territories worldwide, (ii) for the
    +maximum duration provided by applicable law or treaty (including future
    +time extensions), (iii) in any current or future medium and for any number
    +of copies, and (iv) for any purpose whatsoever, including without
    +limitation commercial, advertising or promotional purposes (the
    +"License"). The License shall be deemed effective as of the date CC0 was
    +applied by Affirmer to the Work. Should any part of the License for any
    +reason be judged legally invalid or ineffective under applicable law, such
    +partial invalidity or ineffectiveness shall not invalidate the remainder
    +of the License, and in such case Affirmer hereby affirms that he or she
    +will not (i) exercise any of his or her remaining Copyright and Related
    +Rights in the Work or (ii) assert any associated claims and causes of
    +action with respect to the Work, in either case contrary to Affirmer's
    +express Statement of Purpose.
    +
    +4. Limitations and Disclaimers.
    +
    + a. No trademark or patent rights held by Affirmer are waived, abandoned,
    +    surrendered, licensed or otherwise affected by this document.
    + b. Affirmer offers the Work as-is and makes no representations or
    +    warranties of any kind concerning the Work, express, implied,
    +    statutory or otherwise, including without limitation warranties of
    +    title, merchantability, fitness for a particular purpose, non
    +    infringement, or the absence of latent or other defects, accuracy, or
    +    the present or absence of errors, whether or not discoverable, all to
    +    the greatest extent permissible under applicable law.
    + c. Affirmer disclaims responsibility for clearing rights of other persons
    +    that may apply to the Work or any use thereof, including without
    +    limitation any person's Copyright and Related Rights in the Work.
    +    Further, Affirmer disclaims responsibility for obtaining any necessary
    +    consents, permissions or other rights required for any use of the
    +    Work.
    + d. Affirmer understands and acknowledges that Creative Commons is not a
    +    party to this document and has no duty or obligation with respect to
    +    this CC0 or use of the Work.

    +2. License Grants and Conditions
    +--------------------------------
    +
    +2.1. Grants
    +
    +Each Contributor hereby grants You a world-wide, royalty-free,
    +non-exclusive license:
    +
    +(a) under intellectual property rights (other than patent or trademark)
    +    Licensable by such Contributor to use, reproduce, make available,
    +    modify, display, perform, distribute, and otherwise exploit its
    +    Contributions, either on an unmodified basis, with Modifications, or

    +
    +(b) under Patent Claims of such Contributor to make, use, sell, offer
    +    for sale, have made, import, and otherwise transfer either its
    +    Contributions or its Contributor Version.
    +
    +2.2. Effective Date
    +
    +The licenses granted in Section 2.1 with respect to any Contribution
    +become effective for each Contribution on the date the Contributor first
    +distributes such Contribution.
    +
    +2.3. Limitations on Grant Scope
    +
    +The licenses granted in this Section 2 are the only rights granted under
    +this License. No additional rights or licenses will be implied from the
    +distribution or licensing of Covered Software under this License.
    +Notwithstanding Section 2.1(b) above, no patent license is granted by a
    +Contributor:
    +
    +(a) for any code that a Contributor has removed from Covered Software;
    +    or
    +
    +(b) for infringements caused by: (i) Your and any other third party's
    +    modifications of Covered Software, or (ii) the combination of its
    +    Contributions with other software (except as part of its Contributor
    +    Version); or
    +
    +(c) under Patent Claims infringed by Covered Software in the absence of
    +    its Contributions.
    +
    +This License does not grant any rights in the trademarks, service marks,
    +or logos of any Contributor (except as may be necessary to comply with
    +the notice requirements in Section 3.4).
    +
    +2.4. Subsequent Licenses
    +
    +No Contributor makes additional grants as a result of Your choice to
    +distribute the Covered Software under a subsequent version of this
    +License (see Section 10.2) or under the terms of a Secondary License (if
    +permitted under the terms of Section 3.3).
    +
    +2.5. Representation
    +
    +Each Contributor represents that the Contributor believes its
    +Contributions are its original creation(s) or it has sufficient rights
    +to grant the rights to its Contributions conveyed by this License.
    +
    +2.6. Fair Use
    +
    +This License is not intended to limit any rights You have under
    +applicable copyright doctrines of fair use, fair dealing, or other
    +equivalents.
    +
    +2.7. Conditions
    +
    +Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
    +in Section 2.1.
    +
    +3. Responsibilities
    +-------------------
    +
    +3.1. Distribution of Source Form
    +
    +All distribution of Covered Software in Source Code Form, including any
    +Modifications that You create or to which You contribute, must be under
    +the terms of this License. You must inform recipients that the Source
    +Code Form of the Covered Software is governed by the terms of this
    +License, and how they can obtain a copy of this License. You may not
    +attempt to alter or restrict the recipients' rights in the Source Code
    +Form.
    +
    +3.2. Distribution of Executable Form
    +
    +If You distribute Covered Software in Executable Form then:
    +
    +(a) such Covered Software must also be made available in Source Code
    +    Form, as described in Section 3.1, and You must inform recipients of
    +    the Executable Form how they can obtain a copy of such Source Code
    +    Form by reasonable means in a timely manner, at a charge no more
    +    than the cost of distribution to the recipient; and
    +
    +(b) You may distribute such Executable Form under the terms of this
    +    License, or sublicense it under different terms, provided that the
    +    license for the Executable Form does not attempt to limit or alter
    +    the recipients' rights in the Source Code Form under this License.
    +
    +3.3. Distribution of a Larger Work
    +
    +You may create and distribute a Larger Work under terms of Your choice,
    +provided that You also comply with the requirements of this License for
    +the Covered Software. If the Larger Work is a combination of Covered
    +Software with a work governed by one or more Secondary Licenses, and the
    +Covered Software is not Incompatible With Secondary Licenses, this
    +License permits You to additionally distribute such Covered Software
    +under the terms of such Secondary License(s), so that the recipient of
    +the Larger Work may, at their option, further distribute the Covered
    +Software under the terms of either this License or such Secondary
    +License(s).
    +
    +3.4. Notices
    +
    +You may not remove or alter the substance of any license notices
    +(including copyright notices, patent notices, disclaimers of warranty,
    +or limitations of liability) contained within the Source Code Form of
    +the Covered Software, except that You may alter any license notices to
    +the extent required to remedy known factual inaccuracies.
    +
    +3.5. Application of Additional Terms
    +
    +You may choose to offer, and to charge a fee for, warranty, support,
    +indemnity or liability obligations to one or more recipients of Covered
    +Software. However, You may do so only on Your own behalf, and not on
    +behalf of any Contributor. You must make it absolutely clear that any
    +such warranty, support, indemnity, or liability obligation is offered by
    +You alone, and You hereby agree to indemnify every Contributor for any
    +liability incurred by such Contributor as a result of warranty, support,
    +indemnity or liability terms You offer. You may include additional
    +disclaimers of warranty and limitations of liability specific to any
    +jurisdiction.
    +
    +4. Inability to Comply Due to Statute or Regulation
    +---------------------------------------------------
    +
    +If it is impossible for You to comply with any of the terms of this
    +License with respect to some or all of the Covered Software due to
    +statute, judicial order, or regulation then You must: (a) comply with
    +the terms of this License to the maximum extent possible; and (b)
    +describe the limitations and the code they affect. Such description must
    +be placed in a text file included with all distributions of the Covered
    +Software under this License. Except to the extent prohibited by statute
    +or regulation, such description must be sufficiently detailed for a
    +recipient of ordinary skill to be able to understand it.
    +
    +5. Termination
    +--------------
    +
    +5.1. The rights granted under this License will terminate automatically
    +if You fail to comply with any of its terms. However, if You become
    +compliant, then the rights granted under this License from a particular
    +Contributor are reinstated (a) provisionally, unless and until such
    +Contributor explicitly and finally terminates Your grants, and (b) on an
    +ongoing basis, if such Contributor fails to notify You of the
    +non-compliance by some reasonable means prior to 60 days after You have
    +come back into compliance. Moreover, Your grants from a particular
    +Contributor are reinstated on an ongoing basis if such Contributor
    +notifies You of the non-compliance by some reasonable means, this is the
    +first time You have received notice of non-compliance with this License
    +from such Contributor, and You become compliant prior to 30 days after
    +Your receipt of the notice.
    +
    +5.2. If You initiate litigation against any entity by asserting a patent
    +infringement claim (excluding declaratory judgment actions,
    +counter-claims, and cross-claims) alleging that a Contributor Version
    +directly or indirectly infringes any patent, then the rights granted to
    +You by any and all Contributors for the Covered Software under Section
    +2.1 of this License shall terminate.
    +
    +5.3. In the event of termination under Sections 5.1 or 5.2 above, all
    +end user license agreements (excluding distributors and resellers) which
    +have been validly granted by You or Your distributors under this License
    +prior to termination shall survive termination.

    +*  Covered Software is provided under this License on an "as is"       *
    +*  basis, without warranty of any kind, either expressed, implied, or  *
    +*  statutory, including, without limitation, warranties that the       *
    +*  Covered Software is free of defects, merchantable, fit for a        *
    +*  particular purpose or non-infringing. The entire risk as to the     *

    +*  Should any Covered Software prove defective in any respect, You     *
    +*  (not any Contributor) assume the cost of any necessary servicing,   *
    +*  repair, or correction. This disclaimer of warranty constitutes an   *
    +*  essential part of this License. No use of any Covered Software is   *
    +*  authorized under this License except under this disclaimer.         *
    +*                                                                      *

    +*  permitted above, be liable to You for any direct, indirect,         *
    +*  special, incidental, or consequential damages of any character      *
    +*  including, without limitation, damages for lost profits, loss of    *

    +*  limitation of liability shall not apply to liability for death or   *

    +8. Litigation
    +-------------
    +
    +Any litigation relating to this License may be brought only in the
    +courts of a jurisdiction where the defendant maintains its principal
    +place of business and such litigation shall be governed by laws of that
    +jurisdiction, without reference to its conflict-of-law provisions.
    +Nothing in this Section shall prevent a party's ability to bring
    +cross-claims or counter-claims.
    +
    +9. Miscellaneous
    +----------------
    +
    +This License represents the complete agreement concerning the subject
    +matter hereof. If any provision of this License is held to be
    +unenforceable, such provision shall be reformed only to the extent
    +necessary to make it enforceable. Any law or regulation which provides
    +that the language of a contract shall be construed against the drafter
    +shall not be used to construe this License against a Contributor.
    +

    +
    +10.2. Effect of New Versions

    +steward.
    +
    +10.3. Modified Versions
    +
    +If you create software not governed by this License, and you want to
    +create a new license for such software, you may create and use a
    +modified version of this License if you rename the license and remove
    +any references to the name of the license steward (except to note that
    +such modified license differs from this License).
    +
    +10.4. Distributing Source Code Form that is Incompatible With Secondary
    +Licenses
    +
    +If You choose to distribute Source Code Form that is Incompatible With
    +Secondary Licenses under the terms of this version of the License, the

A higher number makes search more accurate but also slower.
- Most of the time, setting nprobes to cover 5-15% of the dataset should achieve high recall with low latency.
- - _For example_, For a dataset of 1 million vectors divided into 256 partitions, `nprobes` should be set to ~20-40. This value can be adjusted to achieve the optimal balance between search latency and search quality.
- -- **refine_factor** (default: None): Refine the results by reading extra elements and re-ranking them in memory.
- A higher number makes search more accurate but also slower. If you find the recall is less than ideal, try refine_factor=10 to start.
- - _For example_, For a dataset of 1 million vectors divided into 256 partitions, setting the `refine_factor` to 200 will initially retrieve the top 4,000 candidates (top k * refine_factor) from all searched partitions. These candidates are then reranked to determine the final top 20 results.
-!!! note - Both `nprobes` and `refine_factor` are only applicable if an ANN index is present.

For many use-cases, -datasets of the order of ~100K vectors don't require index creation. If you can live with up to -100ms latency, skipping index creation is a simpler workflow while guaranteeing 100% recall. - -### When is it necessary to create an ANN vector index? - -`LanceDB` comes out-of-the-box with highly optimized SIMD code for computing vector similarity. -In our benchmarks, computing distances for 100K pairs of 1K dimension vectors takes **less than 20ms**. -We observe that for small datasets (~100K rows) or for applications that can accept 100ms latency, -vector indices are usually not necessary. - -For large-scale or higher dimension vectors, it can beneficial to create vector index for performance. - -### How big is my index, and how many memory will it take? - -In LanceDB, all vector indices are **disk-based**, meaning that when responding to a vector query, only the relevant pages from the index file are loaded from disk and cached in memory. Additionally, each sub-vector is usually encoded into 1 byte PQ code. - -For example, with a 1024-dimension dataset, if we choose `num_sub_vectors=64`, each sub-vector has `1024 / 64 = 16` float32 numbers. -Product quantization can lead to approximately `16 * sizeof(float32) / 1 = 64` times of space reduction. - -### How to choose `num_partitions` and `num_sub_vectors` for `IVF_PQ` index? - -`num_partitions` is used to decide how many partitions the first level `IVF` index uses. -Higher number of partitions could lead to more efficient I/O during queries and better accuracy, but it takes much more time to train. -On `SIFT-1M` dataset, our benchmark shows that keeping each partition 4K-8K rows lead to a good latency / recall. - -`num_sub_vectors` specifies how many Product Quantization (PQ) short codes to generate on each vector. The number should be a factor of the vector dimension. Because -PQ is a lossy compression of the original vector, a higher `num_sub_vectors` usually results in -less space distortion, and thus yields better accuracy. However, a higher `num_sub_vectors` also causes heavier I/O and more PQ computation, and thus, higher latency. `dimension / num_sub_vectors` should be a multiple of 8 for optimum SIMD efficiency. - -!!! note - if `num_sub_vectors` is set to be greater than the vector dimension, you will see errors like `attempt to divide by zero` - -### How to choose `m` and `ef_construction` for `IVF_HNSW_*` index? - -`m` determines the number of connections a new node establishes with its closest neighbors upon entering the graph. Typically, `m` falls within the range of 5 to 48. Lower `m` values are suitable for low-dimensional data or scenarios where recall is less critical. Conversely, higher `m` values are beneficial for high-dimensional data or when high recall is required. In essence, a larger `m` results in a denser graph with increased connectivity, but at the expense of higher memory consumption. - -`ef_construction` balances build speed and accuracy. Higher values increase accuracy but slow down the build process. A typical range is 150 to 300. For good search results, a minimum value of 100 is recommended. In most cases, setting this value above 500 offers no additional benefit. Ensure that `ef_construction` is always set to a value equal to or greater than `ef` in the search phase diff --git a/docs/src/ann_indexes.ts b/docs/src/ann_indexes.ts deleted file mode 100644 index 0276daad2..000000000 --- a/docs/src/ann_indexes.ts +++ /dev/null @@ -1,54 +0,0 @@ -// --8<-- [start:import] -import * as vectordb from "vectordb"; -// --8<-- [end:import] - -(async () => { - console.log("ann_indexes.ts: start"); - // --8<-- [start:ingest] - const db = await vectordb.connect("data/sample-lancedb"); - - let data = []; - for (let i = 0; i < 10_000; i++) { - data.push({ - vector: Array(1536).fill(i), - id: `${i}`, - content: "", - longId: `${i}`, - }); - } - const table = await db.createTable("my_vectors", data); - await table.createIndex({ - type: "ivf_pq", - column: "vector", - num_partitions: 16, - num_sub_vectors: 48, - }); - // --8<-- [end:ingest] - - // --8<-- [start:search1] - const results_1 = await table - .search(Array(1536).fill(1.2)) - .limit(2) - .nprobes(20) - .refineFactor(10) - .execute(); - // --8<-- [end:search1] - - // --8<-- [start:search2] - const results_2 = await table - .search(Array(1536).fill(1.2)) - .where("id != '1141'") - .limit(2) - .execute(); - // --8<-- [end:search2] - - // --8<-- [start:search3] - const results_3 = await table - .search(Array(1536).fill(1.2)) - .select(["id"]) - .limit(2) - .execute(); - // --8<-- [end:search3] - - console.log("ann_indexes.ts: done"); -})(); diff --git a/docs/src/api_reference.md b/docs/src/api_reference.md deleted file mode 100644 index 0eb22a831..000000000 --- a/docs/src/api_reference.md +++ /dev/null @@ -1,8 +0,0 @@ -# API Reference - -The API reference for the LanceDB client SDKs are available at the following locations: - -- [Python](python/python.md) -- [JavaScript (legacy vectordb package)](javascript/modules.md) -- [JavaScript (newer @lancedb/lancedb package)](js/globals.md) -- [Rust](https://docs.rs/lancedb/latest/lancedb/index.html) diff --git a/docs/src/assets/favicon.ico b/docs/src/assets/favicon.ico new file mode 100644 index 000000000..911581be9 Binary files /dev/null and b/docs/src/assets/favicon.ico differ diff --git a/docs/src/assets/hero-header.png b/docs/src/assets/hero-header.png index 588053722..aa474b06b 100644 Binary files a/docs/src/assets/hero-header.png and b/docs/src/assets/hero-header.png differ diff --git a/docs/src/assets/reverie-banner.png b/docs/src/assets/reverie-banner.png new file mode 100644 index 000000000..d7d49cb3b Binary files /dev/null and b/docs/src/assets/reverie-banner.png differ diff --git a/docs/src/basic.md b/docs/src/basic.md deleted file mode 100644 index 625368ce8..000000000 --- a/docs/src/basic.md +++ /dev/null @@ -1,655 +0,0 @@ -# Quick start - -!!! info "LanceDB can be run in a number of ways:" - - * Embedded within an existing backend (like your Django, Flask, Node.js or FastAPI application) - * Directly from a client application like a Jupyter notebook for analytical workloads - * Deployed as a remote serverless database - -![](assets/lancedb_embedded_explanation.png) - -## Installation - -=== "Python" - - ```shell - pip install lancedb - ``` - -=== "Typescript[^1]" - === "@lancedb/lancedb" - - ```shell - npm install @lancedb/lancedb - ``` - !!! note "Bundling `@lancedb/lancedb` apps with Webpack" - - Since LanceDB contains a prebuilt Node binary, you must configure `next.config.js` to exclude it from webpack.

By following these guidelines, you can ensure a smooth, performant experience with LanceDB Cloud. - -### Should I reuse the database connection? -Yes! It is recommended to establish a single database connection and maintain it throughout your interaction with the tables within. - -LanceDB uses HTTP connections to communicate with the servers. By re-using the Connection object, you avoid the overhead of repeatedly establishing HTTP connections, significantly improving efficiency. - -### Should I re-use the `Table` object? -`table = db.open_table()` should be called once and used for all subsequent table operations. If there are changes to the opened table, `table` always reflect the **latest version** of the data. - -### What should I do if I need to search for rows by `id`? -LanceDB Cloud currently does not support an ID or primary key column. You are recommended to add a -user-defined ID column. To significantly improve the query performance with SQL causes, a scalar BITMAP/BTREE index should be created on this column. - -### What are the vector indexing types supported by LanceDB Cloud? -We support `IVF_PQ` and `IVF_HNSW_SQ` as the `index_type` which is passed to `create_index`. LanceDB Cloud tunes the indexing parameters automatically to achieve the best tradeoff between query latency and query quality. - -### When I add new rows to a table, do I need to manually update the index? -No! LanceDB Cloud triggers an asynchronous background job to index the new vectors. - -Even though indexing is asynchronous, your vectors will still be immediately searchable. LanceDB uses brute-force search to search over unindexed rows. This makes you new data is immediately available, but does increase latency temporarily. To disable the brute-force part of search, set the `fast_search` flag in your query to `true`. - -### Do I need to reindex the whole dataset if only a small portion of the data is deleted or updated? -No! Similar to adding data to the table, LanceDB Cloud triggers an asynchronous background job to update the existing indices. Therefore, no action is needed from users and there is absolutely no -downtime expected. - -### How do I know whether an index has been created? -While index creation in LanceDB Cloud is generally fast, querying immediately after a `create_index` call may result in errors. It's recommended to use `list_indices` to verify index creation before querying. - -### Why is my query latency higher than expected? -Multiple factors can impact query latency. To reduce query latency, consider the following: -- Send pre-warm queries: send a few queries to warm up the cache before an actual user query. -- Check network latency: LanceDB Cloud is hosted in AWS `us-east-1` region. It is recommended to run queries from an EC2 instance that is in the same region. -- Create scalar indices: If you are filtering on metadata, it is recommended to create scalar indices on those columns. This will speedup searches with metadata filtering.

Just like Apache Arrow, Lance is a fast columnar data format, but it has the added benefit of being versionable, query and train ML models on. Lance is designed to be used with simple and complex data types, like tabular data, images, videos audio, 3D point clouds (which are deeply nested) and more. - -The following concepts are important to keep in mind: - -- Data storage is columnar and is interoperable with other columnar formats (such as Parquet) via Arrow -- Data is divided into fragments that represent a subset of the data -- Data is versioned, with each insert operation creating a new version of the dataset and an update to the manifest that tracks versions via metadata - -!!! note - 1. First, each version contains metadata and just the new/updated data in your transaction. So if you have 100 versions, they aren't 100 duplicates of the same data. However, they do have 100x the metadata overhead of a single version, which can result in slower queries. - 2. Second, these versions exist to keep LanceDB scalable and consistent. We do not immediately blow away old versions when creating new ones because other clients might be in the middle of querying the old version. It's important to retain older versions for as long as they might be queried. - -## What are fragments? - -Fragments are chunks of data in a Lance dataset. Each fragment includes multiple files that contain several columns in the chunk of data that it represents. - -## Compaction - -As you insert more data, your dataset will grow and you'll need to perform *compaction* to maintain query throughput (i.e., keep latencies down to a minimum). Compaction is the process of merging fragments together to reduce the amount of metadata that needs to be managed, and to reduce the number of files that need to be opened while scanning the dataset. - -### How does compaction improve performance? - -Compaction performs the following tasks in the background: - -- Removes deleted rows from fragments -- Removes dropped columns from fragments -- Merges small fragments into larger ones - -Depending on the use case and dataset, optimal compaction will have different requirements. As a rule of thumb: - -- It’s always better to use *batch* inserts rather than adding 1 row at a time (to avoid too small fragments). If single-row inserts are unavoidable, run compaction on a regular basis to merge them into larger fragments. -- Keep the number of fragments under 100, which is suitable for most use cases (for *really* large datasets of >500M rows, more fragments might be needed) - -!!! note - - LanceDB Cloud/Enterprise supports [auto-compaction](https://docs.lancedb.com/enterprise/architecture/architecture#write-path) which automatically optimizes fragments in the background as data changes. - -## Deletion - -Although Lance allows you to delete rows from a dataset, it does not actually delete the data immediately. It simply marks the row as deleted in the `DataFile` that represents a fragment. For a given version of the dataset, each fragment can have up to one deletion file (if no rows were ever deleted from that fragment, it will not have a deletion file). This is important to keep in mind because it means that the data is still there, and can be recovered if needed, as long as that version still exists based on your backup policy. - -## Reindexing - -Reindexing is the process of updating the index to account for new data, keeping good performance for queries. This applies to either a full-text search (FTS) index or a vector index. For ANN search, new data will always be included in query results, but queries on tables with unindexed data will fallback to slower search methods for the new parts of the table. This is another important operation to run periodically as your data grows, as it also improves performance. This is especially important if you're appending large amounts of data to an existing dataset. - -!!! tip - When adding new data to a dataset that has an existing index (either FTS or vector), LanceDB doesn't immediately update the index until a reindex operation is complete. - -Both LanceDB OSS and Cloud support reindexing, but the process (at least for now) is different for each, depending on the type of index. - -In LanceDB OSS, re-indexing happens synchronously when you call either `create_index` or `optimize` on a table. In LanceDB Cloud, re-indexing happens asynchronously as you add and update data in your table. - -By default, queries will search new data even if it has yet to be indexed. This is done using brute-force methods, such as kNN for vector search, and combined with the fast index search results. This is done to ensure that you're always searching over all your data, but it does come at a performance cost. Without reindexing, adding more data to a table will make queries slower and more expensive.

HNSW is one of the most accurate and fastest Approximate Nearest Neighbour search algorithms, It’s beneficial in high-dimensional spaces where finding the same nearest neighbor would be too slow and costly - -[Jump to usage](#usage) -There are three main types of ANN search algorithms: - -* **Tree-based search algorithms**: Use a tree structure to organize and store data points. -* **Hash-based search algorithms**: Use a specialized geometric hash table to store and manage data points. These algorithms typically focus on theoretical guarantees, and don't usually perform as well as the other approaches in practice. -* **Graph-based search algorithms**: Use a graph structure to store data points, which can be a bit complex. - -HNSW is a graph-based algorithm. All graph-based search algorithms rely on the idea of a k-nearest neighbor (or k-approximate nearest neighbor) graph, which we outline below. -HNSW also combines this with the ideas behind a classic 1-dimensional search data structure: the skip list. - -## k-Nearest Neighbor Graphs and k-approximate Nearest neighbor Graphs -The k-nearest neighbor graph actually predates its use for ANN search. Its construction is quite simple: - -* Each vector in the dataset is given an associated vertex. -* Each vertex has outgoing edges to its k nearest neighbors. That is, the k closest other vertices by Euclidean distance between the two corresponding vectors. This can be thought of as a "friend list" for the vertex. -* For some applications (including nearest-neighbor search), the incoming edges are also added. - -Eventually, it was realized that the following greedy search method over such a graph typically results in good approximate nearest neighbors: - -* Given a query vector, start at some fixed "entry point" vertex (e.g. the approximate center node). -* Look at that vertex's neighbors. If any of them are closer to the query vector than the current vertex, then move to that vertex. -* Repeat until a local optimum is found. - -The above algorithm also generalizes to e.g. top 10 approximate nearest neighbors. - -Computing a k-nearest neighbor graph is actually quite slow, taking quadratic time in the dataset size. It was quickly realized that near-identical performance can be achieved using a k-approximate nearest neighbor graph. That is, instead of obtaining the k-nearest neighbors for each vertex, an approximate nearest neighbor search data structure is used to build much faster. -In fact, another data structure is not needed: This can be done "incrementally". -That is, if you start with a k-ANN graph for n-1 vertices, you can extend it to a k-ANN graph for n vertices as well by using the graph to obtain the k-ANN for the new vertex. - -One downside of k-NN and k-ANN graphs alone is that one must typically build them with a large value of k to get decent results, resulting in a large index. - - -## HNSW: Hierarchical Navigable Small Worlds - -HNSW builds on k-ANN in two main ways: - -* Instead of getting the k-approximate nearest neighbors for a large value of k, it sparsifies the k-ANN graph using a carefully chosen "edge pruning" heuristic, allowing for the number of edges per vertex to be limited to a relatively small constant. -* The "entry point" vertex is chosen dynamically using a recursively constructed data structure on a subset of the data, similarly to a skip list. - -This recursive structure can be thought of as separating into layers: - -* At the bottom-most layer, an k-ANN graph on the whole dataset is present. -* At the second layer, a k-ANN graph on a fraction of the dataset (e.g. 10%) is present. -* At the Lth layer, a k-ANN graph is present. It is over a (constant) fraction (e.g. 10%) of the vectors/vertices present in the L-1th layer. - -Then the greedy search routine operates as follows: - -* At the top layer (using an arbitrary vertex as an entry point), use the greedy local search routine on the k-ANN graph to get an approximate nearest neighbor at that layer. -* Using the approximate nearest neighbor found in the previous layer as an entry point, find an approximate nearest neighbor in the next layer with the same method. -* Repeat until the bottom-most layer is reached. Then use the entry point to find multiple nearest neighbors (e.g. top 10). - - -## Usage - -There are three key parameters to set when constructing an HNSW index: - -* `metric`: Use an `l2` euclidean distance metric.

Using an ANN index is faster, but less accurate than kNN or brute force search because, in essence, the index is a lossy representation of the data. - -LanceDB is fundamentally different from other vector databases in that it is built on top of [Lance](https://github.com/lancedb/lance), an open-source columnar data format designed for performant ML workloads and fast random access. Due to the design of Lance, LanceDB's indexing philosophy adopts a primarily *disk-based* indexing philosophy. - -## IVF-PQ - -IVF-PQ is a composite index that combines inverted file index (IVF) and product quantization (PQ). The implementation in LanceDB provides several parameters to fine-tune the index's size, query throughput, latency and recall, which are described later in this section. - -### Product quantization - -Quantization is a compression technique used to reduce the dimensionality of an embedding to speed up search. - -Product quantization (PQ) works by dividing a large, high-dimensional vector of size into equally sized subvectors. Each subvector is assigned a "reproduction value" that maps to the nearest centroid of points for that subvector. The reproduction values are then assigned to a codebook using unique IDs, which can be used to reconstruct the original vector. - -![](../assets/ivfpq_pq_desc.png) - -It's important to remember that quantization is a *lossy process*, i.e., the reconstructed vector is not identical to the original vector. This results in a trade-off between the size of the index and the accuracy of the search results. - -As an example, consider starting with 128-dimensional vector consisting of 32-bit floats. Quantizing it to an 8-bit integer vector with 4 dimensions as in the image above, we can significantly reduce memory requirements. - -!!! example "Effect of quantization" - - Original: `128 × 32 = 4096` bits - Quantized: `4 × 8 = 32` bits - - Quantization results in a **128x** reduction in memory requirements for each vector in the index, which is substantial. - -### Inverted file index - -While PQ helps with reducing the size of the index, IVF primarily addresses search performance. The primary purpose of an inverted file index is to facilitate rapid and effective nearest neighbor search by narrowing down the search space. - -In IVF, the PQ vector space is divided into *Voronoi cells*, which are essentially partitions that consist of all the points in the space that are within a threshold distance of the given region's seed point. These seed points are initialized by running K-means over the stored vectors. The centroids of K-means turn into the seed points which then each define a region. These regions are then are used to create an inverted index that correlates each centroid with a list of vectors in the space, allowing a search to be restricted to just a subset of vectors in the index. - -![](../assets/ivfpq_ivf_desc.webp) - -During query time, depending on where the query lands in vector space, it may be close to the border of multiple Voronoi cells, which could make the top-k results ambiguous and span across multiple cells. To address this, the IVF-PQ introduces the `nprobe` parameter, which controls the number of Voronoi cells to search during a query. The higher the `nprobe`, the more accurate the results, but the slower the query. - -![](../assets/ivfpq_query_vector.webp) - -## Putting it all together - -We can combine the above concepts to understand how to build and query an IVF-PQ index in LanceDB. - -### Construct index - -There are three key parameters to set when constructing an IVF-PQ index: - -* `metric`: Use an `l2` euclidean distance metric. We also support `dot` and `cosine` distance. -* `num_partitions`: The number of partitions in the IVF portion of the index. -* `num_sub_vectors`: The number of sub-vectors that will be created during Product Quantization (PQ). - -In Python, the index can be created as follows: - -```python -# Create and train the index for a 1536-dimensional vector -# Make sure you have enough data in the table for an effective training step -tbl.create_index(metric="l2", num_partitions=256, num_sub_vectors=96) -``` -!!! note - `num_partitions`=256 and `num_sub_vectors`=96 does not work for every dataset. Those values needs to be adjusted for your particular dataset. - -The `num_partitions` is usually chosen to target a particular number of vectors per partition. `num_sub_vectors` is typically chosen based on the desired recall and the dimensionality of the vector.

While a higher number enhances search accuracy, it also results in slower performance. Typically, setting `nprobes` to cover 5–10% of the dataset proves effective in achieving high recall with minimal latency. -* `refine_factor`: Refine the results by reading extra elements and re-ranking them in memory. A higher number makes the search more accurate but also slower (see the [FAQ](../faq.md#do-i-need-to-set-a-refine-factor-when-using-an-index) page for more details on this). -* `to_pandas()`: Convert the results to a pandas DataFrame - -And there you have it!

S3 / GCS / Azure Blob Storage - -!!! tip "Lowest cost, highest latency" - - - **Latency** ⇒ Has the highest latency. p95 latency is also substantially worse than p50. In general you get results in the order of several hundred milliseconds - - **Scalability** ⇒ Infinite on storage, however, QPS will be limited by S3 concurrency limits - - **Cost** ⇒ Lowest (order of magnitude cheaper than other options) - - **Reliability/Availability** ⇒ Highly available, as blob storage like S3 are critical infrastructure that form the backbone of the internet. - -Another important point to note is that LanceDB is designed to separate storage from compute, and the underlying Lance format stores the data in numerous immutable fragments. Due to these factors, LanceDB is a great storage option that addresses the _N + 1_ query problem. i.e., when a high query throughput is required, query processes can run in a stateless manner and be scaled up and down as needed. - -### 2. EFS / GCS Filestore / Azure File Storage - -!!! info "Moderately low cost, moderately low latency (<100ms)" - - - **Latency** ⇒ Much better than object/blob storage but not as good as EBS/Local disk; < 100ms p95 achievable - - **Scalability** ⇒ High, but the bottleneck will be the IOPs limit, but when scaling you can provision multiple EFS volumes - - **Cost** ⇒ Significantly more expensive than S3 but still very cost effective compared to in-memory dbs. Inactive data in EFS is also automatically tiered to S3-level costs. - - **Reliability/Availability** ⇒ Highly available, as query nodes can go down without affecting EFS. However, EFS does not provide replication / backup - this must be managed manually. - -A recommended best practice is to keep a copy of the data on S3 for disaster recovery scenarios. If any downtime is unacceptable, then you would need another EFS with a copy of the data. This is still much cheaper than EC2 instances holding multiple copies of the data. - -### 3. Third-party storage solutions - -Solutions like [MinIO](https://blog.min.io/lancedb-trusted-steed-against-data-complexity/), WekaFS, etc. that deliver S3 compatible API with much better performance than S3. - -!!! info "Moderately low cost, moderately low latency (<100ms)" - - - **Latency** ⇒ Should be similar latency to EFS, better than S3 (<100ms) - - **Scalability** ⇒ Up to the solutions architect, who can add as many nodes to their MinIO or other third-party provider's cluster as needed - - **Cost** ⇒ Definitely higher than S3. The cost can be marginally higher than EFS until you get to maybe >10TB scale with high utilization - - **Reliability/Availability** ⇒ These are all shareable by lots of nodes, quality/cost of replication/backup depends on the vendor - - -### 4. EBS / GCP Persistent Disk / Azure Managed Disk - -!!! info "Very low latency (<30ms), higher cost" - - - **Latency** ⇒ Very good, pretty close to local disk. You’re looking at <30ms latency in most cases - - **Scalability** ⇒ EBS is not shareable between instances. If deployed via k8s, it can be shared between pods that live on the same instance, but beyond that you would need to shard data or make an additional copy - - **Cost** ⇒ Higher than EFS. There are some hidden costs to EBS as well if you’re paying for IO. - - **Reliability/Availability** ⇒ Not shareable between instances but can be shared between pods on the same instance. Survives instance termination. No automatic backups. - -Just like EFS, an EBS or persistent disk setup requires more manual work to manage data sharding, backups and capacity. - -### 5. Local disk (SSD/NVMe) - -!!! danger "Lowest latency (<10ms), highest cost" - - - **Latency** ⇒ Lowest latency with modern NVMe drives, <10ms p95 - - **Scalability** ⇒ Difficult to scale on cloud. Also need additional copies / sharding if QPS needs to be higher - - **Cost** ⇒ Highest cost; the main issue with keeping your application and storage tightly integrated is that it’s just not really possible to scale this up in cloud environments - - **Reliability/Availability** ⇒ If the instance goes down, so does your data. You have to be _very_ diligent about backing up your data - -As a rule of thumb, local disk should be your storage option if you require absolutely *crazy low* latency and you’re willing to do a bunch of data management work to make it happen. diff --git a/docs/src/concepts/vector_search.md b/docs/src/concepts/vector_search.md deleted file mode 100644 index 5a6f20187..000000000 --- a/docs/src/concepts/vector_search.md +++ /dev/null @@ -1,36 +0,0 @@ -# Vector search - -Vector search is a technique used to search for similar items based on their vector representations, called embeddings.

In the future, we plan to support the ability to change the embedding function via - table metadata and have LanceDB automatically take care of regenerating the embeddings. - - -## 1. Define the embedding function - -=== "Python" - In the LanceDB python SDK, we define a global embedding function registry with - many different embedding models and even more coming soon. - Here's let's an implementation of CLIP as example. - - ```python - from lancedb.embeddings import get_registry - - registry = get_registry() - clip = registry.get("open-clip").create() - ``` - - You can also define your own embedding function by implementing the `EmbeddingFunction` - abstract base interface. It subclasses Pydantic Model which can be utilized to write complex schemas simply as we'll see next! - -=== "TypeScript" - In the TypeScript SDK, the choices are more limited.

For now, only the OpenAI - embedding function is available.

Define the data model or schema - -=== "Python" - The embedding function defined above abstracts away all the details about the models and dimensions required to define the schema. You can simply set a field as **source** or **vector** column. Here's how: - - ```python - class Pets(LanceModel): - vector: Vector(clip.ndims()) = clip.VectorField() - image_uri: str = clip.SourceField() - ``` - - `VectorField` tells LanceDB to use the clip embedding function to generate query embeddings for the `vector` column and `SourceField` ensures that when adding data, we automatically use the specified embedding function to encode `image_uri`. - -=== "TypeScript" - - For the TypeScript SDK, a schema can be inferred from input data, or an explicit - Arrow schema can be provided. - -## 3.

Querying your table -Not only can you forget about the embeddings during ingestion, you also don't -need to worry about it when you query the table: - -=== "Python" - - Our OpenCLIP query embedding function supports querying via both text and images: - - ```python - results = ( - table.search("dog") - .limit(10) - .to_pandas() - ) - ``` - - Or we can search using an image: - - ```python - p = Path("path/to/images/samoyed_100.jpg") - query_image = Image.open(p) - results = ( - table.search(query_image) - .limit(10) - .to_pandas() - ) - ``` - - Both of the above snippet returns a pandas DataFrame with the 10 closest vectors to the query. - -=== "TypeScript" - - === "@lancedb/lancedb" - - ```ts - const results = await table.search("What's the best pizza topping?") - .limit(10) - .toArray() - ``` - - === "vectordb (deprecated)" - - ```ts - const results = await table - .search("What's the best pizza topping?") - .limit(10) - .execute() - ``` - - The above snippet returns an array of records with the top 10 nearest neighbors to the query. - ---- - -## Rate limit Handling -`EmbeddingFunction` class wraps the calls for source and query embedding generation inside a rate limit handler that retries the requests with exponential backoff after successive failures.

Indexing is a method of organizing these vector embeddings, that allows us to quickly and efficiently locate and retrieve them from the entire dataset of vector embeddings. - -## What types of data/objects can be embedded? - -The following are common types of data that can be embedded: - -1. **Text**: Text data includes sentences, paragraphs, documents, or any written content. -2. **Images**: Image data encompasses photographs, illustrations, or any visual content. -3. **Audio**: Audio data includes sounds, music, speech, or any auditory content. -4. **Video**: Video data consists of moving images and sound, which can convey complex information. - -Large datasets of multi-modal data (text, audio, images, etc.) can be converted into embeddings with the appropriate model. - -!!! tip "LanceDB vs Other traditional Vector DBs" - While many vector databases primarily focus on the storage and retrieval of vector embeddings, **LanceDB** uses **Lance file format** (operates on a disk-based architecture), which allows for the storage and management of not just embeddings but also **raw file data (bytes)**. This capability means that users can integrate various types of data, including images and text, alongside their vector embeddings in a unified system. - - With the ability to store both vectors and associated file data, LanceDB enhances the querying process. Users can perform semantic searches that not only retrieve similar embeddings but also access related files and metadata, thus streamlining the workflow. - -## How does embedding works? - -As mentioned, after creating embedding, each data point is represented as a vector in a n-dimensional space (embedding space). The dimensionality of this space can vary depending on the complexity of the data and the specific embedding technique used. - -Points that are close to each other in vector space are considered similar (or appear in similar contexts), and points that are far away are considered dissimilar. To quantify this closeness, we use distance as a metric which can be measured in the following way - - -1. **Euclidean Distance (l2)**: It calculates the straight-line distance between two points (vectors) in a multidimensional space. -2. **Cosine Similarity**: It measures the cosine of the angle between two vectors, providing a normalized measure of similarity based on their direction. -3. **Dot product**: It is calculated as the sum of the products of their corresponding components. To measure relatedness it considers both the magnitude and direction of the vectors. - -## How do you create and store vector embeddings for your data? - -1. **Creating embeddings**: Choose an embedding model, it can be a pre-trained model (open-source or commercial) or you can train a custom embedding model for your scenario. Then feed your preprocessed data into the chosen model to obtain embeddings. - -??? question "Popular choices for embedding models" - For text data, popular choices are OpenAI’s text-embedding models, Google Gemini text-embedding models, Cohere’s Embed models, and SentenceTransformers, etc. - - For image data, popular choices are CLIP (Contrastive Language–Image Pretraining), Imagebind embeddings by meta (supports audio, video, and image), and Jina multi-modal embeddings, etc. - -2. **Storing vector embeddings**: This effectively requires **specialized databases** that can handle the complexity of vector data, as traditional databases often struggle with this task. Vector databases are designed specifically for storing and querying vector embeddings. They optimize for efficient nearest-neighbor searches and provide built-in indexing mechanisms. - -!!! tip "Why LanceDB" - LanceDB **automates** the entire process of creating and storing embeddings for your data. LanceDB allows you to define and use **embedding functions**, which can be **pre-trained models** or **custom models**. - - This enables you to **generate** embeddings tailored to the nature of your data (e.g., text, images) and **store** both the **original data** and **embeddings** in a **structured schema** thus providing efficient querying capabilities for similarity searches. - -Let's quickly [get started](./index.md) and learn how to manage embeddings in LanceDB. - -## Bonus: As a developer, what you can create using embeddings? - -As a developer, you can create a variety of innovative applications using vector embeddings.

We also have a serverless SaaS solution, LanceDB Cloud, available under a commercial license. - -### What is the difference between Lance and LanceDB? - -[Lance](https://github.com/lancedb/lance) is a modern columnar data format for AI, written in Rust 🦀. It’s perfect for building search engines, feature stores and being the foundation of large-scale ML training jobs requiring high performance IO and shuffles. It also has native support for storing, querying, and inspecting deeply nested data for robotics or large blobs like images, point clouds, and more. - -LanceDB is the vector database that’s built on top of Lance, and utilizes the underlying optimized storage format to build efficient disk-based indexes that power semantic search & retrieval applications, from RAGs to QA Bots to recommender systems. - -### Why invent another data format instead of using Parquet? - -As we mention in our talk titled “[Lance, a modern columnar data format](https://www.youtube.com/watch?v=ixpbVyrsuL8)”, Parquet and other tabular formats that derive from it are rather dated (Parquet is over 10 years old), especially when it comes to random access on vectors. We needed a format that’s able to handle the complex trade-offs involved in shuffling, scanning, OLAP and filtering large datasets involving vectors, and our extensive experiments with Parquet didn't yield sufficient levels of performance for modern ML. [Our benchmarks](https://blog.lancedb.com/benchmarking-random-access-in-lance-ed690757a826) show that Lance is up to 1000x faster than Parquet for random access, which we believe justifies our decision to create a new data format for AI. - -### Why build in Rust? 🦀 - -We believe that the Rust ecosystem has attained mainstream maturity and that Rust will form the underpinnings of large parts of the data and ML landscape in a few years. Performance, latency and reliability are paramount to a vector DB, and building in Rust allows us to iterate and release updates more rapidly due to Rust’s safety guarantees. Both Lance (the data format) and LanceDB (the database) are written entirely in Rust. We also provide Python, JavaScript, and Rust client libraries to interact with the database. - -### What is the difference between LanceDB OSS and LanceDB Cloud? - -LanceDB OSS is an **embedded** (in-process) solution that can be used as the vector store of choice for your LLM and RAG applications. It can be embedded inside an existing application backend, or used in-process alongside existing ML and data engineering pipelines. - -LanceDB Cloud is a **serverless** solution — the database and data sit on the cloud and we manage the scalability of the application side via a remote client, without the need to manage any infrastructure. - -Both flavors of LanceDB benefit from the blazing fast Lance data format and are built on the same open source foundations. - -### What makes LanceDB different? - -LanceDB is among the few embedded vector DBs out there that we believe can unlock a whole new class of LLM-powered applications in the browser or via edge functions. Lance’s multi-modal nature allows you to store the raw data, metadata and the embeddings all at once, unlike other solutions that typically store just the embeddings and metadata. - -The Lance data format that powers our storage system also provides true zero-copy access and seamless interoperability with numerous other data formats (like Pandas, Polars, Pydantic) via Apache Arrow, as well as automatic data versioning and data management without needing extra infrastructure. - -### How large of a dataset can LanceDB handle? - -LanceDB and its underlying data format, Lance, are built to scale to really large amounts of data (hundreds of terabytes). We are currently working with customers who regularly perform operations on 200M+ vectors, and we’re fast approaching billion scale and beyond, which are well-handled by our disk-based indexes, without you having to break the bank. - -### Do I need to build an ANN index to run vector search? - -No. LanceDB is blazing fast (due to its disk-based index) for even brute force kNN search, within reason. In our benchmarks, computing 100K pairs of 1000-dimension vectors takes less than 20ms. For small datasets of ~100K records or applications that can accept ~100ms latency, an ANN index is usually not necessary. - -For large-scale (>1M) or higher dimension vectors, it is beneficial to create an ANN index. See the [ANN indexes](ann_indexes.md) section for more details. - -### Does LanceDB support full-text search? - -Yes, LanceDB supports full-text search (FTS) via [Tantivy](https://github.com/quickwit-oss/tantivy). Our current FTS integration is Python-only, and our goal is to push it down to the Rust level in future versions to enable much more powerful search capabilities available to our Python, JavaScript and Rust clients. Follow along in the [Github issue](https://github.com/lancedb/lance/issues/1195) - -### How can I speed up data inserts? - -It's highly recommend to perform bulk inserts via batches (for e.g., Pandas DataFrames or lists of dicts in Python) to speed up inserts for large datasets. Inserting records one at a time is slow and can result in suboptimal performance because each insert creates a new data fragment on disk. Batching inserts allows LanceDB to create larger fragments (and their associated manifests), which are more efficient to read and write. - -### Do I need to set a refine factor when using an index? - -Yes. LanceDB uses PQ, or Product Quantization, to compress vectors and speed up search when using an ANN index. However, because PQ is a lossy compression algorithm, it tends to reduce recall while also reducing the index size. To address this trade-off, we introduce a process called **refinement**. The normal process computes distances by operating on the compressed PQ vectors. The refinement factor (*rf*) is a multiplier that takes the top-k similar PQ vectors to a given query, fetches `rf * k` *full* vectors and computes the raw vector distances between them and the query vector, reordering the top-k results based on these scores instead. - -For example, if you're retrieving the top 10 results and set `refine_factor` to 25, LanceDB will fetch the 250 most similar vectors (according to PQ), compute the distances again based on the full vectors for those 250 and then re-rank based on their scores. This can significantly improve recall, with a small added latency cost (typically a few milliseconds), so it's recommended you set a `refine_factor` of anywhere between 5-50 and measure its impact on latency prior to deploying your solution. - -### How can I improve IVF-PQ recall while keeping latency low? - -When using an IVF-PQ index, there's a trade-off between recall and latency at query time. You can improve recall by increasing the number of probes and the `refine_factor`. In our benchmark on the GIST-1M dataset, we show that it's possible to achieve >0.95 recall with a latency of under 10 ms on most systems, using ~50 probes and a `refine_factor` of 50. This is, of course, subject to the dataset at hand and a quick sensitivity study can be performed on your own data.

In order to connect to a MinIO instance, you need to: - -- Set the envvar `AWS_ENDPOINT` to the URL of your MinIO API -- Set the envvars `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` with your MinIO credential -- Call `lancedb.connect("s3://minio_bucket_name")` - -### Where can I find benchmarks for LanceDB? - -Refer to this [post](https://blog.lancedb.com/benchmarking-lancedb-92b01032874a) for recent benchmarks. - -### How much data can LanceDB practically manage without effecting performance? - -We target good performance on ~10-50 billion rows and ~10-30 TB of data. - -### Does LanceDB support concurrent operations? - -LanceDB can handle concurrent reads very well, and can scale horizontally.

LanceDB will abort these uploads when it shuts down gracefully, such as when cancelled by keyboard interrupt. However, in the rare case that LanceDB crashes, it is possible that some data will be left lingering in your account. To cleanup this data, we recommend (as AWS themselves do) that you setup a lifecycle rule to delete in-progress uploads after 7 days. See the AWS guide: - - **[Configuring a bucket lifecycle configuration to delete incomplete multipart uploads](https://docs.aws.amazon.com/AmazonS3/latest/userguide/mpu-abort-incomplete-mpu-lifecycle-config.html)** - -#### AWS IAM Permissions - -If a bucket is private, then an IAM policy must be specified to allow access to it. For many development scenarios, using broad permissions such as a PowerUser account is more than sufficient for working with LanceDB. However, in many production scenarios, you may wish to have as narrow as possible permissions. - -For **read and write access**, LanceDB will need a policy such as: - -```json -{ - "Version": "2012-10-17", - "Statement": [ - { - "Effect": "Allow", - "Action": [ - "s3:PutObject", - "s3:GetObject", - "s3:DeleteObject" - ], - "Resource": "arn:aws:s3::://*" - }, - { - "Effect": "Allow", - "Action": [ - "s3:ListBucket", - "s3:GetBucketLocation" - ], - "Resource": "arn:aws:s3:::", - "Condition": { - "StringLike": { - "s3:prefix": [ - "/*" - ] - } - } - } - ] -} -``` - -For **read-only access**, LanceDB will need a policy such as: - -```json -{ - "Version": "2012-10-17", - "Statement": [ - { - "Effect": "Allow", - "Action": [ - "s3:GetObject" - ], - "Resource": "arn:aws:s3::://*" - }, - { - "Effect": "Allow", - "Action": [ - "s3:ListBucket", - "s3:GetBucketLocation" - ], - "Resource": "arn:aws:s3:::", - "Condition": { - "StringLike": { - "s3:prefix": [ - "/*" - ] - } - } - } - ] -} -``` - -#### DynamoDB Commit Store for concurrent writes - -By default, S3 does not support concurrent writes. Having two or more processes -writing to the same table at the same time can lead to data corruption. This is -because S3, unlike other object stores, does not have any atomic put or copy -operation. - -To enable concurrent writes, you can configure LanceDB to use a DynamoDB table -as a commit store. This table will be used to coordinate writes between -different processes. To enable this feature, you must modify your connection -URI to use the `s3+ddb` scheme and add a query parameter `ddbTableName` with the -name of the table to use. - -=== "Python" - - === "Sync API" - - ```python - import lancedb - db = lancedb.connect( - "s3+ddb://bucket/path?ddbTableName=my-dynamodb-table", - ) - ``` - === "Async API" - - ```python - import lancedb - async_db = await lancedb.connect_async( - "s3+ddb://bucket/path?ddbTableName=my-dynamodb-table", - ) - ``` - -=== "JavaScript" - - ```javascript - const lancedb = require("lancedb"); - - const db = await lancedb.connect( - "s3+ddb://bucket/path?ddbTableName=my-dynamodb-table", - ); - ``` - -The DynamoDB table must be created with the following schema: - -- Hash key: `base_uri` (string) -- Range key: `version` (number) - -You can create this programmatically with: - -=== "Python" - - - ```python - import boto3 - - dynamodb = boto3.client("dynamodb") - table = dynamodb.create_table( - TableName=table_name, - KeySchema=[ - {"AttributeName": "base_uri", "KeyType": "HASH"}, - {"AttributeName": "version", "KeyType": "RANGE"}, - ], - AttributeDefinitions=[ - {"AttributeName": "base_uri", "AttributeType": "S"}, - {"AttributeName": "version", "AttributeType": "N"}, - ], - ProvisionedThroughput={"ReadCapacityUnits": 1, "WriteCapacityUnits": 1}, - ) - ``` - -=== "JavaScript" - - - ```javascript - import { - CreateTableCommand, - DynamoDBClient, - } from "@aws-sdk/client-dynamodb"; - - const dynamodb = new DynamoDBClient({ - region: CONFIG.awsRegion, - credentials: { - accessKeyId: CONFIG.awsAccessKeyId, - secretAccessKey: CONFIG.awsSecretAccessKey, - }, - endpoint: CONFIG.awsEndpoint, - }); - const command = new CreateTableCommand({ - TableName: table_name, - AttributeDefinitions: [ - { - AttributeName: "base_uri", - AttributeType: "S", - }, - { - AttributeName: "version", - AttributeType: "N", - }, - ], - KeySchema: [ - { AttributeName: "base_uri", KeyType: "HASH" }, - { AttributeName: "version", KeyType: "RANGE" }, - ], - ProvisionedThroughput: { - ReadCapacityUnits: 1, - WriteCapacityUnits: 1, - }, - }); - await client.send(command); - ``` - - -#### S3-compatible stores - -LanceDB can also connect to S3-compatible stores, such as MinIO.

This setting is suitable for applications where the data does not change during the lifetime of the table reference. -2. **Zero seconds (Strong consistency)**: The database checks for updates on every read. This provides the strongest consistency guarantees, ensuring that all clients see the latest committed data. However, it has the most overhead. This setting is suitable when consistency matters more than having high QPS. -3. **Custom interval (Eventual consistency)**: The database checks for updates at a custom interval, such as every 5 seconds. This provides eventual consistency, allowing for some lag between write and read operations. Performance wise, this is a middle ground between strong consistency and no consistency check. This setting is suitable for applications where immediate consistency is not critical, but clients should see updated data eventually. - -!!! tip "Consistency in LanceDB Cloud" - - This is only tune-able in LanceDB OSS.

- -### Conclusion - -The results show that the reranking methods are able to improve the search results. However, the improvement is not consistent across all rerankers. The choice of reranker depends on the dataset and the application. It is also important to note that the reranking methods are not a replacement for the search methods. They are complementary and should be used together to get the best results. The speed to recall tradeoff is also an important factor to consider when choosing the reranker. diff --git a/docs/src/hybrid_search/hybrid_search.md b/docs/src/hybrid_search/hybrid_search.md deleted file mode 100644 index 89f74fc4d..000000000 --- a/docs/src/hybrid_search/hybrid_search.md +++ /dev/null @@ -1,63 +0,0 @@ -# Hybrid Search - -LanceDB supports both semantic and keyword-based search (also termed full-text search, or FTS).

Supposed to create an index. |`1000`| - -??? Tip "Wonder! What is `Document` class?" - We know that, before storing the data in vectorDB, we need to split the data into smaller chunks upon which embeddings will be created and these embeddings along with the chunks will be stored in vectorDB. When the user queries over the vectorDB, some of these embeddings will be returned as the result based on the semantic similarity with the query. - - When the user queries over vectorDB, the queries are converted into embeddings, and a nearest neighbor search is performed over these query embeddings which returns the embeddings that correspond to most semantically similar chunks(parts of our data) present in vectorDB. - - Here, a “Document” is a class in phidata. Since there is an option to let phidata create and manage embeddings, it splits our data into smaller chunks(as expected). It does not directly create embeddings on it. Instead, it takes each chunk and encapsulates it inside the object of the `Document` class along with various other metadata related to the chunk. Then embeddings are created on these `Document` objects and stored in vectorDB. - - ```python - class Document(BaseModel): - """Model for managing a document""" - - content: str # <--- here data of chunk is stored - id: Optional[str] = None - name: Optional[str] = None - meta_data: Dict[str, Any] = {} - embedder: Optional[Embedder] = None - embedding: Optional[List[float]] = None - usage: Optional[Dict[str, Any]] = None - ``` - -However, using phidata you can load many other types of data in the knowledge base(other than text).

It updates existing records if a document with the same identifier does exist, or inserts new records if no matching record exists. This is useful for maintaining the most current information without manually checking for existence. - -During the Load operation, phidata directly interacts with the LanceDB library and performs the loading of the table with our data in the following steps - - -1. **Creates** and **initializes** the table if it does not exist. - -2. Then it **splits** our data into smaller **chunks**. - - ??? question "How do they create chunks?" - **phidata** provides many types of **Knowledge Bases** based on the type of data. Most of them :material-information-outline:{ title="except LlamaIndexKnowledgeBase and LangChainKnowledgeBase"} has a property method called `document_lists` of type `Iterator[List[Document]]`. During the load operation, this property method is invoked. It traverses on the data provided by us (in this case, a text file(s)) using `reader`. Then it **reads**, **creates chunks**, and **encapsulates** each chunk inside a `Document` object and yields **lists of `Document` objects** that contain our data. - -3. Then **embeddings** are created on these chunks are **inserted** into the LanceDB Table - - ??? question "How do they insert your data as different rows in LanceDB Table?" - The chunks of your data are in the form - **lists of `Document` objects**. It was yielded in the step above. - - for each `Document` in `List[Document]`, it does the following operations: - - - Creates embedding on `Document`. - - Cleans the **content attribute**(chunks of our data is here) of `Document`. - - Prepares data by creating `id` and loading `payload` with the metadata related to this chunk. (1) - { .annotate } - - 1. Three columns will be added to the table - `"id"`, `"vector"`, and `"payload"` (payload contains various metadata including **`content`**) - - - Then add this data to LanceTable. - -4.

A scalar index can speed up scans that contain filter expressions on the indexed column. For example, the following scan will be faster if the column `my_col` has a scalar index: ```ts const con = await lancedb.connect('./.lancedb'); const table = await con.openTable('images'); const results = await table.where('my_col = 7').execute(); ``` Scalar indices can also speed up scans containing a vector search and a prefilter: ```ts const con = await lancedb.connect('././lancedb'); const table = await con.openTable('images'); const results = await table.search([1.0, 2.0]).where('my_col != 7').prefilter(true); ``` Scalar indices can only speed up scans for basic filters using equality, comparison, range (e.g. `my_col BETWEEN 0 AND 100`), and set membership (e.g. `my_col IN (0, 1, 2)`) Scalar indices can be used if the filter contains multiple indexed columns and the filter criteria are AND'd or OR'd together (e.g. `my_col < 0 AND other_col> 100`) Scalar indices may be used if the filter contains non-indexed columns but, depending on the structure of the filter, they may not be usable. For example, if the column `not_indexed` does not have a scalar index then the filter `my_col = 0 OR not_indexed = 1` will not be able to use any scalar index on `my_col`. | - -#### Returns - -`Promise`\<`void`\> - -**`Examples`** - -```ts -const con = await lancedb.connect('././lancedb') -const table = await con.openTable('images') -await table.createScalarIndex('my_col') -``` - -#### Implementation of - -[Table](../interfaces/Table.md).[createScalarIndex](../interfaces/Table.md#createscalarindex) - -#### Defined in - -[index.ts:1011](https://github.com/lancedb/lancedb/blob/92179835/node/src/index.ts#L1011) - -___ - -### delete - -▸ **delete**(`filter`): `Promise`\<`void`\> - -Delete rows from this table. - -#### Parameters - -| Name | Type | Description | -| :------ | :------ | :------ | -| `filter` | `string` | A filter in the same format used by a sql WHERE clause. | - -#### Returns - -`Promise`\<`void`\> - -#### Implementation of - -[Table](../interfaces/Table.md).[delete](../interfaces/Table.md#delete) - -#### Defined in - -[index.ts:1030](https://github.com/lancedb/lancedb/blob/92179835/node/src/index.ts#L1030) - -___ - -### dropColumns - -▸ **dropColumns**(`columnNames`): `Promise`\<`void`\> - -Drop one or more columns from the dataset - -This is a metadata-only operation and does not remove the data from the -underlying storage.

A scalar index can speed up scans that contain filter expressions on the indexed column. For example, the following scan will be faster if the column `my_col` has a scalar index: ```ts const con = await lancedb.connect('./.lancedb'); const table = await con.openTable('images'); const results = await table.where('my_col = 7').execute(); ``` Scalar indices can also speed up scans containing a vector search and a prefilter: ```ts const con = await lancedb.connect('././lancedb'); const table = await con.openTable('images'); const results = await table.search([1.0, 2.0]).where('my_col != 7').prefilter(true); ``` Scalar indices can only speed up scans for basic filters using equality, comparison, range (e.g. `my_col BETWEEN 0 AND 100`), and set membership (e.g. `my_col IN (0, 1, 2)`) Scalar indices can be used if the filter contains multiple indexed columns and the filter criteria are AND'd or OR'd together (e.g. `my_col < 0 AND other_col> 100`) Scalar indices may be used if the filter contains non-indexed columns but, depending on the structure of the filter, they may not be usable. For example, if the column `not_indexed` does not have a scalar index then the filter `my_col = 0 OR not_indexed = 1` will not be able to use any scalar index on `my_col`. | - -##### Returns - -`Promise`\<`void`\> - -**`Examples`** - -```ts -const con = await lancedb.connect('././lancedb') -const table = await con.openTable('images') -await table.createScalarIndex('my_col') -``` - -#### Defined in - -[index.ts:449](https://github.com/lancedb/lancedb/blob/92179835/node/src/index.ts#L449) - -___ - -### delete - -• **delete**: (`filter`: `string`) => `Promise`\<`void`\> - -#### Type declaration - -▸ (`filter`): `Promise`\<`void`\> - -Delete rows from this table. - -This can be used to delete a single row, many rows, all rows, or -sometimes no rows (if your predicate matches nothing). - -##### Parameters - -| Name | Type | Description | -| :------ | :------ | :------ | -| `filter` | `string` | A filter in the same format used by a sql WHERE clause.

I didn't write essays. I wrote what beginning writers were supposed to write then, and probably still are: short stories. My stories were awful. They had hardly any plot, just characters with strong feelings, which I imagined made them deep.\n", - "\n", - "The first programs I tried writing were on the IBM 1401 that our school district used for what was then called \"data processing.\" This was in 9th grade, so I was 13 or 14. The school district's 1401 happened to be in the basement of our junior high school, and my friend Rich Draves and I got permission to use it. It was like a mini Bond villain's lair down there, with all these alien-looking machines — CPU, disk drives, printer, card reader — sitting up on a raised floor under bright fluorescent lights.\n", - "\n", - "The language we used was an early version of Fortran. You had to type programs on punch cards, then stack them in the card reader and press a button to load the program into memory and run it. The result would ordinarily be to print something on the spectacularly loud printer.\n", - "\n", - "I was puzzled by the 1401. I couldn't figure out what to do with it. And in retrospect there's not much I could have done with it. The only form of input to programs was data stored on punched cards, and I didn't have any data stored on punched cards. The only other option was to do things that didn't rely on any input, like calculate approximations of pi, but I didn't know enough math to do anything interesting of that type. So I'm not surprised I can't remember any programs I wrote, because they can't have done much. My clearest memory is of the moment I learned it was possible for programs not to terminate, when one of mine didn't. On a machine without time-sharing, this was a social as well as a technical error, as the data center manager's expression made clear.\n", - "\n", - "With microcomputers, everything changed. Now you could have a computer sitting right in front of you, on a desk, that could respond to your keystrokes as it was running instead of just churning through a stack of punch cards and then stopping. [1]\n", - "\n", - "The first of my friends to get a microcomputer built it himself. It was sold as a kit by Heathkit. I remember vividly how impressed and envious I felt watching him sitting in front of it, typing programs right into the computer.\n", - "\n", - "Computers were expensive in those days and it took me years of nagging before I convinced my father to buy one, a TRS-80, in about 1980. The gold standard then was the Apple II, but a TRS-80 was good enough. This was when I really started programming. I wrote simple games, a program to predict how high my model rockets would fly, and a word processor that my father used to write at least one book. There was only room in memory for about 2 pages of text, so he'd write 2 pages at a time and then print them out, but it was a lot better than a typewriter.\n", - "\n", - "Though I liked programming, I didn't plan to study it in college. In college I was going to study philosophy, which sounded much more powerful. It seemed, to my naive high school self, to be the study of the ultimate truths, compared to which the things studied in other fields would be mere domain knowledge. What I discovered when I got to college was that the other fields took up so much of the space of ideas that there wasn't much left for these supposed ultimate truths. All that seemed left for philosophy were edge cases that people in other fields felt could safely be ignored.\n", - "\n", - "I couldn't have put this into words when I was 18.

They enable interaction with humans through intuitive\\nchat interfaces, which has led to rapid and widespread adoption among the general public.\\nThecapabilitiesofLLMsareremarkableconsideringtheseeminglystraightforwardnatureofthetraining\\nmethodology.

There have been public releases of pretrained LLMs\\n(such as BLOOM (Scao et al., 2022), LLaMa-1 (Touvron et al., 2023), and Falcon (Penedo et al., 2023)) that\\nmatch the performance of closed pretrained competitors like GPT-3 (Brown et al., 2020) and Chinchilla\\n(Hoffmann et al., 2022), but none of these models are suitable substitutes for closed \\u201cproduct\\u201d LLMs, such\\nasChatGPT,BARD,andClaude. TheseclosedproductLLMsareheavilyfine-tunedtoalignwithhuman\\npreferences, which greatly enhances their usability and safety. This step can require significant costs in\\ncomputeandhumanannotation,andisoftennottransparentoreasilyreproducible,limitingprogresswithin\\nthe community to advance AI alignment research.\\nIn this work, we develop and release Llama 2, a family of pretrained and fine-tuned LLMs, Llama 2 and\\nLlama 2-Chat , at scales up to 70B parameters. On the series of helpfulness and safety benchmarks we tested,\\nLlama 2-Chat models generally perform better than existing open-source models. They also appear to\\nbe on par with some of the closed-source models, at least on the human evaluations we performed (see\\nFigures1and3). Wehavetakenmeasurestoincreasethesafetyofthesemodels,usingsafety-specificdata\\nannotation and tuning, as well as conducting red-teaming and employing iterative evaluations. Additionally,\\nthispapercontributesathoroughdescriptionofourfine-tuningmethodologyandapproachtoimproving\\nLLM safety. We hope that this openness will enable the community to reproduce fine-tuned LLMs and\\ncontinue to improve the safety of those models, paving the way for more responsible development of LLMs.\\nWealsosharenovelobservationswemadeduringthedevelopmentof Llama 2 andLlama 2-Chat ,suchas\\nthe emergence of tool usage and temporal organization of knowledge.\\n3\"\n ],\n \"semantic_type\": \"\",\n \"description\": \"\"\n }\n },\n {\n \"column\": \"answer\",\n \"properties\": {\n \"dtype\": \"string\",\n \"num_unique_values\": 220,\n \"samples\": [\n \"Scholars performed a diagnostic analysis to investigate the AI ethics associated with ChatGPT.

This includes employing enhanced safety measures at both the input and output stages of model interaction, as well as carefully tuning the model according to specific use-case requirements to prevent any potential misuse. Additionally, users must comply with the terms set in the Acceptable Use Policy, ensuring their applications do not contravene applicable laws, regulations, and ethical standards.

Anarchism calls for the abolition of the state, which it holds to be unnecessary, undesirable, and harmful. As a historically left-wing movement, placed on the farthest left of the political spectrum, it is usually described alongside communalism and libertarian Marxism as the libertarian wing (libertarian socialism) of the socialist movement, and has a strong historical association with anti-capitalism and socialism.\\n\\nHumans lived in societies without formal hierarchies long before the establishment of formal states, realms, or empires. With the rise of organised hierarchical bodies, scepticism toward authority also rose. Although traces of anarchist thought are found throughout history, modern anarchism emerged from the Enlightenment. During the latter half of the 19th and the first decades of the 20th century, the anarchist movement flourished in most parts of the world and had a significant role in workers\\' struggles for emancipation. Various anarchist schools of thought formed during this period. Anarchists have taken part in several revolutions, most notably in the Paris Commune, the Russian Civil War and the Spanish Civil War, whose end marked the end of the classical era of anarchism. In the last decades of the 20th and into the 21st century, the anarchist movement has been resurgent once more.\\n\\nAnarchism employs a diversity of tactics in order to meet its ideal ends which can be broadly separated into revolutionary and evolutionary tactics; there is significant overlap between the two, which are merely descriptive. Revolutionary tactics aim to bring down authority and state, having taken a violent turn in the past, while evolutionary tactics aim to prefigure what an anarchist society would be like. Anarchist thought, criticism, and praxis have played a part in diverse areas of human society. Criticism of anarchism include claims that it is internally inconsistent, violent, or utopian.\\n\\nEtymology, terminology, and definition \\n\\nThe etymological origin of anarchism is from the Ancient Greek anarkhia, meaning \"without a ruler\", composed of the prefix an- (\"without\") and the word arkhos (\"leader\" or \"ruler\"). The suffix -ism denotes the ideological current that favours anarchy. Anarchism appears in English from 1642 as anarchisme and anarchy from 1539; early English usages emphasised a sense of disorder. Various factions within the French Revolution labelled their opponents as anarchists, although few such accused shared many views with later anarchists. Many revolutionaries of the 19th century such as William Godwin (1756–1836) and Wilhelm Weitling (1808–1871) would contribute to the anarchist doctrines of the next generation but did not use anarchist or anarchism in describing themselves or their beliefs.\\n\\nThe first political philosopher to call himself an anarchist () was Pierre-Joseph Proudhon (1809–1865), marking the formal birth of anarchism in the mid-19th century. Since the 1890s and beginning in France, libertarianism has often been used as a synonym for anarchism and its use as a synonym is still common outside the United States. Some usages of libertarianism refer to individualistic free-market philosophy only, and free-market anarchism in particular is termed libertarian anarchism.\\n\\nWhile the term libertarian has been largely synonymous with anarchism, its meaning has more recently diluted with wider adoption from ideologically disparate groups, including both the New Left and libertarian Marxists, who do not associate themselves with authoritarian socialists or a vanguard party, and extreme cultural liberals, who are primarily concerned with civil liberties. Additionally, some anarchists use libertarian socialist to avoid anarchism\\'s negative connotations and emphasise its connections with socialism. Anarchism is broadly used to describe the anti-authoritarian wing of the socialist movement. Anarchism is contrasted to socialist forms which are state-oriented or from above. Scholars of anarchism generally highlight anarchism\\'s socialist credentials and criticise attempts at creating dichotomies between the two. Some scholars describe anarchism as having many influences from liberalism, and being both liberals and socialists but more so, while most scholars reject anarcho-capitalism as a misunderstanding of anarchist principles.\\n\\nWhile opposition to the state is central to anarchist thought, defining anarchism is not an easy task for scholars, as there is a lot of discussion among scholars and anarchists on the matter, and various currents perceive anarchism slightly differently. Major definitional elements include the will for a non-coercive society, the rejection of the state apparatus, the belief that human nature allows humans to exist in or progress toward such a non-coercive society, and a suggestion on how to act to pursue the ideal of anarchy.\\n\\nHistory\\n\\nPre-modern era \\n\\nBefore the establishment of towns and cities, an established authority did not exist. It was after the creation of institutions of authority that anarchistic ideas espoused as a reaction. The most notable precursors to anarchism in the ancient world were in China and Greece. In China, philosophical anarchism (the discussion on the legitimacy of the state) was delineated by Taoist philosophers Zhuang Zhou and Laozi. Alongside Stoicism, Taoism has been said to have had \"significant anticipations\" of anarchism.\\n \\nAnarchic attitudes were also articulated by tragedians and philosophers in Greece. Aeschylus and Sophocles used the myth of Antigone to illustrate the conflict between rules set by the state and personal autonomy. Socrates questioned Athenian authorities constantly and insisted on the right of individual freedom of conscience. Cynics dismissed human law (nomos) and associated authorities while trying to live according to nature (physis). Stoics were supportive of a society based on unofficial and friendly relations among its citizens without the presence of a state.\\n\\nIn medieval Europe, there was no anarchistic activity except some ascetic religious movements. These, and other Muslim movements, later gave birth to religious anarchism. In the Sasanian Empire, Mazdak called for an egalitarian society and the abolition of monarchy, only to be soon executed by Emperor Kavad I.\\n\\nIn Basra, religious sects preached against the state. In Europe, various sects developed anti-state and libertarian tendencies. Renewed interest in antiquity during the Renaissance and in private judgment during the Reformation restored elements of anti-authoritarian secularism, particularly in France. Enlightenment challenges to intellectual authority (secular and religious) and the revolutions of the 1790s and 1848 all spurred the ideological development of what became the era of classical anarchism.\\n\\nModern era \\nDuring the French Revolution, partisan groups such as the Enragés and the saw a turning point in the fermentation of anti-state and federalist sentiments. The first anarchist currents developed throughout the 18th century as William Godwin espoused philosophical anarchism in England, morally delegitimising the state, Max Stirner\\'s thinking paved the way to individualism and Pierre-Joseph Proudhon\\'s theory of mutualism found fertile soil in France. By the late 1870s, various anarchist schools of thought had become well-defined and a wave of then unprecedented globalisation occurred from 1880 to 1914. This era of classical anarchism lasted until the end of the Spanish Civil War and is considered the golden age of anarchism.\\n\\nDrawing from mutualism, Mikhail Bakunin founded collectivist anarchism and entered the International Workingmen\\'s Association, a class worker union later known as the First International that formed in 1864 to unite diverse revolutionary currents. The International became a significant political force, with Karl Marx being a leading figure and a member of its General Council. Bakunin\\'s faction (the Jura Federation) and Proudhon\\'s followers (the mutualists) opposed state socialism, advocating political abstentionism and small property holdings. After bitter disputes, the Bakuninists were expelled from the International by the Marxists at the 1872 Hague Congress. Anarchists were treated similarly in the Second International, being ultimately expelled in 1896. Bakunin famously predicted that if revolutionaries gained power by Marx\\'s terms, they would end up the new tyrants of workers. In response to their expulsion from the First International, anarchists formed the St. Imier International. Under the influence of Peter Kropotkin, a Russian philosopher and scientist, anarcho-communism overlapped with collectivism. Anarcho-communists, who drew inspiration from the 1871 Paris Commune, advocated for free federation and for the distribution of goods according to one\\'s needs.\\n\\nAt the turn of the century, anarchism had spread all over the world. It was a notable feature of the international syndicalism movement. In China, small groups of students imported the humanistic pro-science version of anarcho-communism. Tokyo was a hotspot for rebellious youth from countries of the far east, travelling to the Japanese capital to study. In Latin America, Argentina was a stronghold for anarcho-syndicalism, where it became the most prominent left-wing ideology. During this time, a minority of anarchists adopted tactics of revolutionary political violence. This strategy became known as propaganda of the deed. The dismemberment of the French socialist movement into many groups and the execution and exile of many Communards to penal colonies following the suppression of the Paris Commune favoured individualist political expression and acts. Even though many anarchists distanced themselves from these terrorist acts, infamy came upon the movement and attempts were made to exclude them from American immigration, including the Immigration Act of 1903, also called the Anarchist Exclusion Act. Illegalism was another strategy which some anarchists adopted during this period.\\n\\nDespite concerns, anarchists enthusiastically participated in the Russian Revolution in opposition to the White movement; however, they met harsh suppression after the Bolshevik government was stabilised. Several anarchists from Petrograd and Moscow fled to Ukraine, notably leading to the Kronstadt rebellion and Nestor Makhno\\'s struggle in the Free Territory. With the anarchists being crushed in Russia, two new antithetical currents emerged, namely platformism and synthesis anarchism. The former sought to create a coherent group that would push for revolution while the latter were against anything that would resemble a political party. Seeing the victories of the Bolsheviks in the October Revolution and the resulting Russian Civil War, many workers and activists turned to communist parties which grew at the expense of anarchism and other socialist movements. In France and the United States, members of major syndicalist movements such as the General Confederation of Labour and the Industrial Workers of the World left their organisations and joined the Communist International.\\n\\nIn the Spanish Civil War of 1936, anarchists and syndicalists (CNT and FAI) once again allied themselves with various currents of leftists. A long tradition of Spanish anarchism led to anarchists playing a pivotal role in the war. In response to the army rebellion, an anarchist-inspired movement of peasants and workers, supported by armed militias, took control of Barcelona and of large areas of rural Spain, where they collectivised the land. The Soviet Union provided some limited assistance at the beginning of the war, but the result was a bitter fight among communists and anarchists at a series of events named May Days as Joseph Stalin tried to seize control of the Republicans.\\n\\nPost-war era \\n\\nAt the end of World War II, the anarchist movement was severely weakened. The 1960s witnessed a revival of anarchism, likely caused by a perceived failure of Marxism–Leninism and tensions built by the Cold War. During this time, anarchism found a presence in other movements critical towards both capitalism and the state such as the anti-nuclear, environmental, and peace movements, the counterculture of the 1960s, and the New Left. It also saw a transition from its previous revolutionary nature to provocative anti-capitalist reformism. Anarchism became associated with punk subculture as exemplified by bands such as Crass and the Sex Pistols. The established feminist tendencies of anarcha-feminism returned with vigour during the second wave of feminism. Black anarchism began to take form at this time and influenced anarchism\\'s move from a Eurocentric demographic. This coincided with its failure to gain traction in Northern Europe and its unprecedented height in Latin America.\\n\\nAround the turn of the 21st century, anarchism grew in popularity and influence within anti-capitalist, anti-war and anti-globalisation movements. Anarchists became known for their involvement in protests against the World Trade Organization (WTO), the Group of Eight and the World Economic Forum. During the protests, ad hoc leaderless anonymous cadres known as black blocs engaged in rioting, property destruction and violent confrontations with the police. Other organisational tactics pioneered in this time include affinity groups, security culture and the use of decentralised technologies such as the Internet. A significant event of this period was the confrontations at the 1999 Seattle WTO conference. Anarchist ideas have been influential in the development of the Zapatistas in Mexico and the Democratic Federation of Northern Syria, more commonly known as Rojava, a de facto autonomous region in northern Syria.\\n\\nThought \\n\\nAnarchist schools of thought have been generally grouped into two main historical traditions, social anarchism and individualist anarchism, owing to their different origins, values and evolution. The individualist current emphasises negative liberty in opposing restraints upon the free individual, while the social current emphasises positive liberty in aiming to achieve the free potential of society through equality and social ownership. In a chronological sense, anarchism can be segmented by the classical currents of the late 19th century and the post-classical currents (anarcha-feminism, green anarchism, and post-anarchism) developed thereafter.\\n\\nBeyond the specific factions of anarchist movements which constitute political anarchism lies philosophical anarchism which holds that the state lacks moral legitimacy, without necessarily accepting the imperative of revolution to eliminate it. A component especially of individualist anarchism, philosophical anarchism may tolerate the existence of a minimal state but claims that citizens have no moral obligation to obey government when it conflicts with individual autonomy. Anarchism pays significant attention to moral arguments since ethics have a central role in anarchist philosophy. Anarchism\\'s emphasis on anti-capitalism, egalitarianism, and for the extension of community and individuality sets it apart from anarcho-capitalism and other types of economic libertarianism.\\n\\nAnarchism is usually placed on the far-left of the political spectrum. Much of its economics and legal philosophy reflect anti-authoritarian, anti-statist, libertarian, and radical interpretations of left-wing and socialist politics such as collectivism, communism, individualism, mutualism, and syndicalism, among other libertarian socialist economic theories. As anarchism does not offer a fixed body of doctrine from a single particular worldview, many anarchist types and traditions exist and varieties of anarchy diverge widely. One reaction against sectarianism within the anarchist milieu was anarchism without adjectives, a call for toleration and unity among anarchists first adopted by Fernando Tarrida del Mármol in 1889 in response to the bitter debates of anarchist theory at the time. Belief in political nihilism has been espoused by anarchists. Despite separation, the various anarchist schools of thought are not seen as distinct entities but rather as tendencies that intermingle and are connected through a set of uniform principles such as individual and local autonomy, mutual aid, network organisation, communal democracy, justified authority and decentralisation.\\n\\nClassical \\n\\nInceptive currents among classical anarchist currents were mutualism and individualism. They were followed by the major currents of social anarchism (collectivist, communist and syndicalist). They differ on organisational and economic aspects of their ideal society.\\n\\nMutualism is an 18th-century economic theory that was developed into anarchist theory by Pierre-Joseph Proudhon. Its aims include reciprocity, free association, voluntary contract, federation and monetary reform of both credit and currency that would be regulated by a bank of the people. Mutualism has been retrospectively characterised as ideologically situated between individualist and collectivist forms of anarchism. In What Is Property? (1840), Proudhon first characterised his goal as a \"third form of society, the synthesis of communism and property.\" Collectivist anarchism is a revolutionary socialist form of anarchism commonly associated with Mikhail Bakunin. Collectivist anarchists advocate collective ownership of the means of production which is theorised to be achieved through violent revolution and that workers be paid according to time worked, rather than goods being distributed according to need as in communism. Collectivist anarchism arose alongside Marxism but rejected the dictatorship of the proletariat despite the stated Marxist goal of a collectivist stateless society.\\n\\nAnarcho-communism is a theory of anarchism that advocates a communist society with common ownership of the means of production, direct democracy and a horizontal network of voluntary associations, workers\\' councils and worker cooperatives, with production and consumption based on the guiding principle \"From each according to his ability, to each according to his need.\" Anarcho-communism developed from radical socialist currents after the French Revolution but was first formulated as such in the Italian section of the First International. It was later expanded upon in the theoretical work of Peter Kropotkin, whose specific style would go onto become the dominating view of anarchists by the late 19th century. Anarcho-syndicalism is a branch of anarchism that views labour syndicates as a potential force for revolutionary social change, replacing capitalism and the state with a new society democratically self-managed by workers. The basic principles of anarcho-syndicalism are direct action, workers\\' solidarity and workers\\' self-management.\\n\\nIndividualist anarchism is a set of several traditions of thought within the anarchist movement that emphasise the individual and their will over any kinds of external determinants. Early influences on individualist forms of anarchism include William Godwin, Max Stirner, and Henry David Thoreau. Through many countries, individualist anarchism attracted a small yet diverse following of Bohemian artists and intellectuals as well as young anarchist outlaws in what became known as illegalism and individual reclamation.\\n\\nPost-classical and contemporary \\n\\nAnarchist principles undergird contemporary radical social movements of the left. Interest in the anarchist movement developed alongside momentum in the anti-globalisation movement, whose leading activist networks were anarchist in orientation. As the movement shaped 21st century radicalism, wider embrace of anarchist principles signaled a revival of interest. Anarchism has continued to generate many philosophies and movements, at times eclectic, drawing upon various sources and combining disparate concepts to create new philosophical approaches. The anti-capitalist tradition of classical anarchism has remained prominent within contemporary currents.\\n\\nContemporary news coverage which emphasizes black bloc demonstrations has reinforced anarchism\\'s historical association with chaos and violence. Its publicity has also led more scholars in fields such as anthropology and history to engage with the anarchist movement, although contemporary anarchism favours actions over academic theory. Various anarchist groups, tendencies, and schools of thought exist today, making it difficult to describe the contemporary anarchist movement. While theorists and activists have established \"relatively stable constellations of anarchist principles\", there is no consensus on which principles are core and commentators describe multiple anarchisms, rather than a singular anarchism, in which common principles are shared between schools of anarchism while each group prioritizes those principles differently. Gender equality can be a common principle, although it ranks as a higher priority to anarcha-feminists than anarcho-communists.\\n\\nAnarchists are generally committed against coercive authority in all forms, namely \"all centralized and hierarchical forms of government (e.g., monarchy, representative democracy, state socialism, etc.), economic class systems (e.g., capitalism, Bolshevism, feudalism, slavery, etc.), autocratic religions (e.g., fundamentalist Islam, Roman Catholicism, etc.), patriarchy, heterosexism, white supremacy, and imperialism.\" Anarchist schools disagree on the methods by which these forms should be opposed. The principle of equal liberty is closer to anarchist political ethics in that it transcends both the liberal and socialist traditions. This entails that liberty and equality cannot be implemented within the state, resulting in the questioning of all forms of domination and hierarchy.\\n\\nTactics \\nAnarchists\\' tactics take various forms but in general serve two major goals, namely to first oppose the Establishment and secondly to promote anarchist ethics and reflect an anarchist vision of society, illustrating the unity of means and ends. A broad categorisation can be made between aims to destroy oppressive states and institutions by revolutionary means on one hand and aims to change society through evolutionary means on the other. Evolutionary tactics embrace nonviolence, reject violence and take a gradual approach to anarchist aims, although there is significant overlap between the two.\\n\\nAnarchist tactics have shifted during the course of the last century. Anarchists during the early 20th century focused more on strikes and militancy while contemporary anarchists use a broader array of approaches.\\n\\nClassical era tactics \\n\\nDuring the classical era, anarchists had a militant tendency. Not only did they confront state armed forces, as in Spain and Ukraine, but some of them also employed terrorism as propaganda of the deed. Assassination attempts were carried out against heads of state, some of which were successful. Anarchists also took part in revolutions. Many anarchists, especially the Galleanists, believed that these attempts would be the impetus for a revolution against capitalism and the state. Many of these attacks were done by individual assailants and the majority took place in the late 1870s, the early 1880s and the 1890s, with some still occurring in the early 1900s. Their decrease in prevalence was the result of further judicial power and targeting and cataloging by state institutions.\\n\\nAnarchist perspectives towards violence have always been controversial. Anarcho-pacifists advocate for non-violence means to achieve their stateless, nonviolent ends. Other anarchist groups advocate direct action, a tactic which can include acts of sabotage or terrorism. This attitude was quite prominent a century ago when seeing the state as a tyrant and some anarchists believing that they had every right to oppose its oppression by any means possible. Emma Goldman and Errico Malatesta, who were proponents of limited use of violence, stated that violence is merely a reaction to state violence as a necessary evil.\\n\\nAnarchists took an active role in strike actions, although they tended to be antipathetic to formal syndicalism, seeing it as reformist. They saw it as a part of the movement which sought to overthrow the state and capitalism. Anarchists also reinforced their propaganda within the arts, some of whom practiced naturism and nudism. Those anarchists also built communities which were based on friendship and were involved in the news media.\\n\\nRevolutionary tactics \\n\\nIn the current era, Italian anarchist Alfredo Bonanno, a proponent of insurrectionary anarchism, has reinstated the debate on violence by rejecting the nonviolence tactic adopted since the late 19th century by Kropotkin and other prominent anarchists afterwards. Both Bonanno and the French group The Invisible Committee advocate for small, informal affiliation groups, where each member is responsible for their own actions but works together to bring down oppression utilizing sabotage and other violent means against state, capitalism, and other enemies. Members of The Invisible Committee were arrested in 2008 on various charges, terrorism included.\\n\\nOverall, contemporary anarchists are much less violent and militant than their ideological ancestors. They mostly engage in confronting the police during demonstrations and riots, especially in countries such as Canada, Greece, and Mexico. Militant black bloc protest groups are known for clashing with the police; however, anarchists not only clash with state operators, they also engage in the struggle against fascists and racists, taking anti-fascist action and mobilizing to prevent hate rallies from happening.\\n\\nEvolutionary tactics \\nAnarchists commonly employ direct action. This can take the form of disrupting and protesting against unjust hierarchy, or the form of self-managing their lives through the creation of counter-institutions such as communes and non-hierarchical collectives. Decision-making is often handled in an anti-authoritarian way, with everyone having equal say in each decision, an approach known as horizontalism. Contemporary-era anarchists have been engaging with various grassroots movements that are more or less based on horizontalism, although not explicitly anarchist, respecting personal autonomy and participating in mass activism such as strikes and demonstrations. In contrast with the big-A anarchism of the classical era, the newly coined term small-a anarchism signals their tendency not to base their thoughts and actions on classical-era anarchism or to refer to classical anarchists such as Peter Kropotkin and Pierre-Joseph Proudhon to justify their opinions. Those anarchists would rather base their thought and praxis on their own experience which they will later theorize.\\n\\nThe decision-making process of small anarchist affinity groups plays a significant tactical role. Anarchists have employed various methods in order to build a rough consensus among members of their group without the need of a leader or a leading group. One way is for an individual from the group to play the role of facilitator to help achieve a consensus without taking part in the discussion themselves or promoting a specific point. Minorities usually accept rough consensus, except when they feel the proposal contradicts anarchist ethics, goals and values. Anarchists usually form small groups (5–20 individuals) to enhance autonomy and friendships among their members. These kinds of groups more often than not interconnect with each other, forming larger networks. Anarchists still support and participate in strikes, especially wildcat strikes as these are leaderless strikes not organised centrally by a syndicate.\\n\\nAs in the past, newspapers and journals are used, and anarchists have gone online in the World Wide Web to spread their message. Anarchists have found it easier to create websites because of distributional and other difficulties, hosting electronic libraries and other portals. Anarchists were also involved in developing various software that are available for free. The way these hacktivists work to develop and distribute resembles the anarchist ideals, especially when it comes to preserving users\\' privacy from state surveillance.\\n\\nAnarchists organize themselves to squat and reclaim public spaces. During important events such as protests and when spaces are being occupied, they are often called Temporary Autonomous Zones (TAZ), spaces where art, poetry, and surrealism are blended to display the anarchist ideal. As seen by anarchists, squatting is a way to regain urban space from the capitalist market, serving pragmatical needs and also being an exemplary direct action. Acquiring space enables anarchists to experiment with their ideas and build social bonds. Adding up these tactics while having in mind that not all anarchists share the same attitudes towards them, along with various forms of protesting at highly symbolic events, make up a carnivalesque atmosphere that is part of contemporary anarchist vividity.\\n\\nKey issues \\n\\nAs anarchism is a philosophy that embodies many diverse attitudes, tendencies, and schools of thought; disagreement over questions of values, ideology, and tactics is common. Its diversity has led to widely different uses of identical terms among different anarchist traditions which has created a number of definitional concerns in anarchist theory. The compatibility of capitalism, nationalism, and religion with anarchism is widely disputed, and anarchism enjoys complex relationships with ideologies such as communism, collectivism, Marxism, and trade unionism. Anarchists may be motivated by humanism, divine authority, enlightened self-interest, veganism, or any number of alternative ethical doctrines. Phenomena such as civilisation, technology (e.g. within anarcho-primitivism), and the democratic process may be sharply criticised within some anarchist tendencies and simultaneously lauded in others.\\n\\nGender, sexuality, and free love \\n\\nAs gender and sexuality carry along them dynamics of hierarchy, many anarchists address, analyse, and oppose the suppression of one\\'s autonomy imposed by gender roles.\\n\\nSexuality was not often discussed by classical anarchists but the few that did felt that an anarchist society would lead to sexuality naturally developing. Sexual violence was a concern for anarchists such as Benjamin Tucker, who opposed age of consent laws, believing they would benefit predatory men. A historical current that arose and flourished during 1890 and 1920 within anarchism was free love. In contemporary anarchism, this current survives as a tendency to support polyamory and queer anarchism. Free love advocates were against marriage, which they saw as a way of men imposing authority over women, largely because marriage law greatly favoured the power of men. The notion of free love was much broader and included a critique of the established order that limited women\\'s sexual freedom and pleasure. Those free love movements contributed to the establishment of communal houses, where large groups of travelers, anarchists and other activists slept in beds together. Free love had roots both in Europe and the United States; however, some anarchists struggled with the jealousy that arose from free love. Anarchist feminists were advocates of free love, against marriage, and pro-choice (utilising a contemporary term), and had a similar agenda. Anarchist and non-anarchist feminists differed on suffrage but were supportive of one another.\\n\\nDuring the second half of the 20th century, anarchism intermingled with the second wave of feminism, radicalising some currents of the feminist movement and being influenced as well. By the latest decades of the 20th century, anarchists and feminists were advocating for the rights and autonomy of women, gays, queers and other marginalised groups, with some feminist thinkers suggesting a fusion of the two currents. With the third wave of feminism, sexual identity and compulsory heterosexuality became a subject of study for anarchists, yielding a post-structuralist critique of sexual normality. Some anarchists distanced themselves from this line of thinking, suggesting that it leaned towards an individualism that was dropping the cause of social liberation.\\n\\nAnarchism and education \\n\\nThe interest of anarchists in education stretches back to the first emergence of classical anarchism. Anarchists consider proper education, one which sets the foundations of the future autonomy of the individual and the society, to be an act of mutual aid. Anarchist writers such as William Godwin (Political Justice) and Max Stirner (\"The False Principle of Our Education\") attacked both state education and private education as another means by which the ruling class replicate their privileges.\\n\\nIn 1901, Catalan anarchist and free thinker Francisco Ferrer established the Escuela Moderna in Barcelona as an opposition to the established education system which was dictated largely by the Catholic Church. Ferrer\\'s approach was secular, rejecting both state and church involvement in the educational process whilst giving pupils large amounts of autonomy in planning their work and attendance. Ferrer aimed to educate the working class and explicitly sought to foster class consciousness among students. The school closed after constant harassment by the state and Ferrer was later arrested. Nonetheless, his ideas formed the inspiration for a series of modern schools around the world. Christian anarchist Leo Tolstoy, who published the essay Education and Culture, also established a similar school with its founding principle being that \"for education to be effective it had to be free.\" In a similar token, A. S. Neill founded what became the Summerhill School in 1921, also declaring being free from coercion.\\n\\nAnarchist education is based largely on the idea that a child\\'s right to develop freely and without manipulation ought to be respected and that rationality would lead children to morally good conclusions; however, there has been little consensus among anarchist figures as to what constitutes manipulation. Ferrer believed that moral indoctrination was necessary and explicitly taught pupils that equality, liberty and social justice were not possible under capitalism, along with other critiques of government and nationalism.\\n\\nLate 20th century and contemporary anarchist writers (Paul Goodman, Herbert Read, and Colin Ward) intensified and expanded the anarchist critique of state education, largely focusing on the need for a system that focuses on children\\'s creativity rather than on their ability to attain a career or participate in consumerism as part of a consumer society. Contemporary anarchists such as Ward claim that state education serves to perpetuate socioeconomic inequality.\\n\\nWhile few anarchist education institutions have survived to the modern-day, major tenets of anarchist schools, among them respect for child autonomy and relying on reasoning rather than indoctrination as a teaching method, have spread among mainstream educational institutions. Judith Suissa names three schools as explicitly anarchists schools, namely the Free Skool Santa Cruz in the United States which is part of a wider American-Canadian network of schools, the Self-Managed Learning College in Brighton, England, and the Paideia School in Spain.\\n\\nAnarchism and the state \\n\\nObjection to the state and its institutions is a sine qua non of anarchism. Anarchists consider the state as a tool of domination and believe it to be illegitimate regardless of its political tendencies. Instead of people being able to control the aspects of their life, major decisions are taken by a small elite. Authority ultimately rests solely on power, regardless of whether that power is open or transparent, as it still has the ability to coerce people. Another anarchist argument against states is that the people constituting a government, even the most altruistic among officials, will unavoidably seek to gain more power, leading to corruption. Anarchists consider the idea that the state is the collective will of the people to be an unachievable fiction due to the fact that the ruling class is distinct from the rest of society.\\n\\nSpecific anarchist attitudes towards the state vary. Robert Paul Wolff believed that the tension between authority and autonomy would mean the state could never be legitimate. Bakunin saw the state as meaning \"coercion, domination by means of coercion, camouflaged if possible but unceremonious and overt if need be.\" A. John Simmons and Leslie Green, who leaned toward philosophical anarchism, believed that the state could be legitimate if it is governed by consensus, although they saw this as highly unlikely. Beliefs on how to abolish the state also differ.\\n\\nAnarchism and the arts \\n\\nThe connection between anarchism and art was quite profound during the classical era of anarchism, especially among artistic currents that were developing during that era such as futurists, surrealists and others. In literature, anarchism was mostly associated with the New Apocalyptics and the neo-romanticism movement. In music, anarchism has been associated with music scenes such as punk. Anarchists such as Leo Tolstoy and Herbert Read stated that the border between the artist and the non-artist, what separates art from a daily act, is a construct produced by the alienation caused by capitalism and it prevents humans from living a joyful life.\\n\\nOther anarchists advocated for or used art as a means to achieve anarchist ends. In his book Breaking the Spell: A History of Anarchist Filmmakers, Videotape Guerrillas, and Digital Ninjas, Chris Robé claims that \"anarchist-inflected practices have increasingly structured movement-based video activism.\" Throughout the 20th century, many prominent anarchists (Peter Kropotkin, Emma Goldman, Gustav Landauer and Camillo Berneri) and publications such as Anarchy wrote about matters pertaining to the arts.\\n\\nThree overlapping properties made art useful to anarchists. It could depict a critique of existing society and hierarchies, serve as a prefigurative tool to reflect the anarchist ideal society and even turn into a means of direct action such as in protests. As it appeals to both emotion and reason, art could appeal to the whole human and have a powerful effect. The 19th-century neo-impressionist movement had an ecological aesthetic and offered an example of an anarchist perception of the road towards socialism. In Les chataigniers a Osny by anarchist painter Camille Pissarro, the blending of aesthetic and social harmony is prefiguring an ideal anarchistic agrarian community.\\n\\nAnalysis \\nThe most common critique of anarchism is that humans cannot self-govern and so a state is necessary for human survival. Philosopher Bertrand Russell supported this critique, stating that \"[p]eace and war, tariffs, regulations of sanitary conditions and the sale of noxious drugs, the preservation of a just system of distribution: these, among others, are functions which could hardly be performed in a community in which there was no central government.\" Another common criticism of anarchism is that it fits a world of isolation in which only the small enough entities can be self-governing; a response would be that major anarchist thinkers advocated anarchist federalism.\\n\\nPhilosophy lecturer Andrew G. Fiala composed a list of common arguments against anarchism which includes critiques such as that anarchism is innately related to violence and destruction, not only in the pragmatic world, such as at protests, but in the world of ethics as well. Secondly, anarchism is evaluated as unfeasible or utopian since the state cannot be defeated practically. This line of arguments most often calls for political action within the system to reform it. The third argument is that anarchism is self-contradictory. While it advocates for no-one to archiei, if accepted by the many, then anarchism would turn into the ruling political theory. In this line of criticism also comes the self-contradiction that anarchism calls for collective action whilst endorsing the autonomy of the individual, hence no collective action can be taken. Lastly, Fiala mentions a critique towards philosophical anarchism of being ineffective (all talk and thoughts) and in the meantime capitalism and bourgeois class remains strong.\\n\\nPhilosophical anarchism has met the criticism of members of academia following the release of pro-anarchist books such as A. John Simmons\\' Moral Principles and Political Obligations. Law professor William A. Edmundson authored an essay to argue against three major philosophical anarchist principles which he finds fallacious. Edmundson says that while the individual does not owe the state a duty of obedience, this does not imply that anarchism is the inevitable conclusion and the state is still morally legitimate. In The Problem of Political Authority, Michael Huemer defends philosophical anarchism, claiming that \"political authority is a moral illusion.\"\\n\\nOne of the earliest criticisms is that anarchism defies and fails to understand the biological inclination to authority. Joseph Raz states that the acceptance of authority implies the belief that following their instructions will afford more success. Raz believes that this argument is true in following both authorities\\' successful and mistaken instruction. Anarchists reject this criticism because challenging or disobeying authority does not entail the disappearance of its advantages by acknowledging authority such as doctors or lawyers as reliable, nor does it involve a complete surrender of independent judgment. Anarchist perception of human nature, rejection of the state, and commitment to social revolution has been criticised by academics as naive, overly simplistic, and unrealistic, respectively. Classical anarchism has been criticised for relying too heavily on the belief that the abolition of the state will lead to human cooperation prospering.\\n\\nFriedrich Engels, considered to be one of the principal founders of Marxism, criticised anarchism\\'s anti-authoritarianism as inherently counter-revolutionary because in his view a revolution is by itself authoritarian. Academic John Molyneux writes in his book Anarchism: A Marxist Criticism that \"anarchism cannot win\", believing that it lacks the ability to properly implement its ideas. The Marxist criticism of anarchism is that it has a utopian character because all individuals should have anarchist views and values. According to the Marxist view, that a social idea would follow directly from this human ideal and out of the free will of every individual formed its essence. Marxists state that this contradiction was responsible for their inability to act. In the anarchist vision, the conflict between liberty and equality was resolved through coexistence and intertwining.\\n\\nSee also \\n\\n Anarchism by country\\n Governance without government\\n List of anarchist political ideologies\\n List of books about anarchism\\n\\nReferences\\n\\nCitations\\n\\nNotes\\n\\nSources\\n\\nPrimary sources\\n\\nSecondary sources\\n\\nTertiary sources\\n\\nFurther reading \\n \\n Criticism of philosophical anarchism.\\n \\n A defence of philosophical anarchism, stating that \"both kinds of \\'anarchism\\' [i.e. philosophical and political anarchism] are philosophical and political claims.\" (p.\\xa0137)\\n Anarchistic popular fiction novel.\\n \\n \\n \\n An argument for philosophical anarchism.\\n\\nExternal links \\n Anarchy Archives.

En 1905, il occupe la chaire de grammaire comparée au Collège de France, où il consacre ses cours à l'histoire et à la structure des langues indo-européennes. Il succéda au linguiste Auguste Carrière à la tête de la chaire d'arménien à l'École des langues orientales.\\n\\nSecrétaire de la Société de linguistique de Paris, il est élu à l'Académie des inscriptions et belles-lettres en 1924.

Antoine Meillet devait diriger la thèse de Jean Paulhan sur la sémantique du proverbe et c'est lui qui découvrit Gustave Guillaume.\\n\\nIl a influencé aussi un certain nombre de linguistes étrangers. Il a également été le premier à identifier le phénomène de la grammaticalisation.\\n\\nSelon le linguiste allemand Walter Porzig, Meillet est un « grand précurseur ». Il montre, par exemple, que, dans les dialectes indo-européens, les groupes indo-européens sont le résultat historique d'une variation diatopique.\\n\\nL’acte de naissance de la sociolinguistique est signé par Antoine Meillet fondateur de la sociolinguistique qui s’est opposé au Cours de linguistique générale de Ferdinand de Saussure dès son apparition en 1916 en le critiquant sur plusieurs plans.\\n\\nÉtudes arméniennes \\n 1890 : une mission de trois mois dans le Caucase lui permet d'apprendre l'arménien moderne.\\n 1902 : il obtient la chaire d'arménien de l'École des langues orientales.\\n 1903 : nouvelle mission en Arménie russe, il publie son Esquisse d'une grammaire comparée de l'arménien classique, qui demeure une référence en linguistique arménienne et indo-européenne jusqu'à ce jour.

The ancestor of many groups also known as the Irish Republican Army, and distinguished from them as the \"Old IRA\", it was descended from the Irish Volunteers, an organisation established on 25 November 1913 that staged the Easter Rising in April 1916. In 1919, the Irish Republic that had been proclaimed during the Easter Rising was formally established by an elected assembly (Dáil Éireann), and the Irish Volunteers were recognised by Dáil Éireann as its legitimate army. Thereafter, the IRA waged a guerrilla campaign against the British occupation of Ireland in the 1919–1921 Irish War of Independence.\n", - "\n", - "Following the signing in 1921 of the Anglo-Irish Treaty, which ended the War of Independence, a split occurred within the IRA. Members who supported the treaty formed the nucleus of the Irish National Army. However, the majority of the IRA was opposed to the treaty. The anti-treaty IRA fought a civil war against the Free State Army in 1922–23, with the intention of creating a fully independent all-Ireland republic. Having lost the civil war, this group remained in existence, with the intention of overthrowing the governments of both the Irish Free State and Northern Ireland and achieving the Irish Republic proclaimed in 1916.\n", - "\n", - "Origins\n", - "\n", - "The Irish Volunteers, founded in 1913, staged the Easter Rising, which aimed at ending British rule in Ireland, in 1916. Following the suppression of the Rising, thousands of Volunteers were imprisoned or interned, leading to the break-up of the organisation. It was reorganised in 1917 following the release of first the internees and then the prisoners. At the army convention held in Dublin in October 1917, Éamon de Valera was elected president, Michael Collins Director for Organisation and Cathal Brugha Chairman of the Resident Executive, which in effect made him Chief of Staff.\n", - "\n", - "Following the success of Sinn Féin in the general election of 1918 and the setting up of the First Dáil (the legislature of the Irish Republic), Volunteers commenced military action against the Royal Irish Constabulary (RIC), the paramilitary police force in Ireland, and subsequently against the British Army. It began with the Soloheadbeg Ambush, when members of the Third Tipperary Brigade led by Séumas Robinson, Seán Treacy, Dan Breen and Seán Hogan, seized a quantity of gelignite, killing two RIC constables in the process.\n", - "\n", - "The Dáil leadership worried that the Volunteers would not accept its authority, given that, under their own constitution, they were bound to obey their own executive and no other body. In August 1919, Brugha proposed to the Dáil that the Volunteers be asked to swear allegiance to the Dáil, but one commentator states that another year passed before the movement took an oath of allegiance to the Irish Republic and its government in \"August 1920\". In sharp contrast, a contemporary in the struggle for Irish independence notes that by late 1919, the term \"Irish Republican Army (IRA)\" was replacing \"Volunteers\" in everyday usage. This change is attributed to the Volunteers, having accepted the authority of the Dáil, being referred to as the \"army of the Irish Republic\", popularly known as the \"Irish Republican Army\".\n", - "\n", - "A power struggle continued between Brugha and Collins, both cabinet ministers, over who had the greater influence. Brugha was nominally the superior as Minister for Defence, but Collins's power base came from his position as Director of Organisation of the IRA and from his membership on the Supreme Council of the Irish Republican Brotherhood (IRB). De Valera resented Collins's clear power and influence, which he saw as coming more from the secretive IRB than from his position as a Teachta Dála (TD) and minister in the Aireacht. Brugha and de Valera both urged the IRA to undertake larger, more conventional military actions for the propaganda effect but were ignored by Collins and Mulcahy. Brugha at one stage proposed the assassination of the entire British cabinet. This was also discounted due to its presumed negative effect on British public opinion. Moreover, many members of the Dáil, notably Arthur Griffith, did not approve of IRA violence and would have preferred a campaign of passive resistance to the British rule. The Dáil belatedly accepted responsibility for IRA actions in April 1921, just three months before the end of the Irish War of Independence.\n", - "\n", - "In practice, the IRA was commanded by Collins, with Richard Mulcahy as second in command. These men were able to issue orders and directives to IRA guerrilla units around the country and at times to send arms and organisers to specific areas. However, because of the localised and irregular character of the war, they were only able to exert limited control over local IRA commanders such as Tom Barry, Liam Lynch in Cork and Seán Mac Eoin in Longford.\n", - "\n", - "The IRA claimed a total strength of 70,000, but only about 3,000 were actively engaged in fighting against the Crown. The IRA distrusted those Irishmen who had fought in the British Army during the First World War as potential informers, but there were a number of exceptions such as Emmet Dalton, Tom Barry and Martin Doyle. The IRA divided its members into three classes, namely \"unreliable\", \"reliable\" and \"active\". The \"unreliable\" members were those who were nominally IRA members but did not do very much for the struggle, \"reliable\" members played a supporting role in the war while occasionally fighting and the \"active\" men those who were engaged in full-time fighting. Of the IRA brigades only about one to two-thirds were considered to be \"reliable\" while those considered \"active\" were even smaller. A disproportionate number of the \"active\" IRA men were teachers, medical students, shoemakers and bootmakers; those engaged in building trades like painters, carpenters and bricklayers; draper's assistants and creamery workers. The Canadian historian Peter Hart wrote \"...the guerrillas were disproportionately skilled, trained and urban\". Farmers and fishermen tended to be underrepresented in the IRA. Those Irishmen engaged in white-collar trades or working as skilled labourers were much more likely to be involved in cultural nationalist groups like the Gaelic League than farmers or fishermen, and thus to have a stronger sense of Irish nationalism. Furthermore, the authority of the Crown tended to be stronger in towns and cities than in the countryside. Thus, those engaged in Irish nationalist activities in urban areas were much more likely to come into conflict with the Crown, leading to a greater chance of radicalisation. Finally, the British tactic of blowing up the homes of IRA members had the effect of discouraging many farmers from joining the struggle as the destruction of the family farm could easily reduce a farmer and his family to destitution. Of the \"active\" IRA members, three-quarters were in their late teens or early 20s and only 5% of the \"active\" men were in the age range of 40 or older. The \"active\" members were overwhelmingly single men with only 4% being married or engaged in a relationship. The life of an \"active\" IRA man with its stress of living on the run and constantly being in hiding tended to attract single men who could adjust to this lifestyle far more easily than a man in a relationship. Furthermore, the IRA preferred to recruit single men as it was found that singles could devote themselves more wholeheartedly to the struggle.\n", - "\n", - "Women were active in the republican movement, but almost no women fought with the IRA whose \"active\" members were almost entirely male. The IRA was not a sectarian group and went out of its way to proclaim it was open to all Irishmen, but its membership was largely Catholic with virtually no Protestants serving as \"active\" IRA men. Hart wrote that in his study of the IRA membership that he found only three Protestants serving as \"active\" IRA men between 1919 and 1921. Of the 917 IRA men convicted by British courts under the Defence of the Realm Act in 1919, only one was a Protestant. The majority of those serving in the IRA were practising Catholics, but there was a large minority of \"pagans\" as atheists or non-practising Catholics were known in Ireland. The majority of the IRA men serving in metropolitan Britain were permanent residents with very few sent over from Ireland. The majority of the IRA men operating in Britain were Irish-born, but there a substantial minority who were British-born, something that made them especially insistent on asserting their Irish identity.\n", - "\n", - "Irish War of Independence\n", - "\n", - "IRA campaign and organisation\n", - "\n", - "The IRA fought a guerrilla war against the Crown forces in Ireland from 1919 to July 1921. The most intense period of the war was from November 1920 onwards. The IRA campaign can broadly be split into three phases. The first, in 1919, involved the re-organisation of the Irish Volunteers as a guerrilla army and only sporadic attacks. Organisers such as Ernie O'Malley were sent around the country to set up viable guerrilla units. On paper, there were 100,000 or so Volunteers enrolled after the conscription crisis of 1918. However, only about 15,000 of these participated in the guerrilla war. In 1919, Collins, the IRA's Director of Intelligence, organised the \"Squad\"—an assassination unit based in Dublin which killed police involved in intelligence work (the Irish playwright Brendan Behan's father Stephen Behan was a member of the Squad). Typical of Collins's sardonic sense of humour, the Squad was often referred to as his \"Twelve Apostles\". In addition, there were some arms raids on RIC barracks. By the end of 1919, four Dublin Metropolitan Police and 11 RIC men had been killed. The RIC abandoned most of their smaller rural barracks in late 1919. Around 400 of these were burned in a co-ordinated IRA operation around the country in April 1920.\n", - "\n", - "The second phase of the IRA campaign, roughly from January to July 1920, involved attacks on the fortified police barracks located in the towns. Between January and June 1920, 16 of these were destroyed and 29 badly damaged. Several events of late 1920 greatly escalated the conflict. Firstly, the British declared martial law in parts of the country—allowing for internment and executions of IRA men. Secondly they deployed paramilitary forces, the Black and Tans and Auxiliary Division, and more British Army personnel into the country. Thus, the third phase of the war (roughly August 1920 – July 1921) involved the IRA taking on a greatly expanded British force, moving away from attacking well-defended barracks and instead using ambush tactics. To this end the IRA was re-organised into \"flying columns\"—permanent guerrilla units, usually about 20 strong, although sometimes larger. In rural areas, the flying columns usually had bases in remote mountainous areas.\n", - "\n", - "The most high-profile violence of the war took place in Dublin in November 1920 and is still known as Bloody Sunday. In the early hours of the morning, Collins' \"Squad\" killed fourteen British spies. In reprisal, that afternoon, British forces opened fire on a football crowd at Croke Park, killing 14 civilians. Towards the end of the day, two prominent Republicans and a friend of theirs were arrested and killed by Crown Forces.\n", - "\n", - "While most areas of the country saw some violence in 1919–1921, the brunt of the war was fought in Dublin and the southern province of Munster. In Munster, the IRA carried out a significant number of successful actions against British troops, for instance, the ambushing and killing of 16 of 18 Auxiliaries by Tom Barry's column at Kilmicheal in West Cork in November 1920, or Liam Lynch's men killing 13 British soldiers near Millstreet early in the next year. At the Crossbarry Ambush in March 1921, 100 or so of Barry's men fought a sizeable engagement with a British column of 1,200, escaping from the British encircling manoeuvre. In Dublin, the \"Squad\" and elements of the IRA Dublin Brigade were amalgamated into the \"Active Service Unit\", under Oscar Traynor, which tried to carry out at least three attacks on British troops a day. Usually, these consisted of shooting or grenade attacks on British patrols. Outside Dublin and Munster, there were only isolated areas of intense activity. For instance, the County Longford IRA under Seán Mac Eoin carried out a number of well-planned ambushes and successfully defended the village of Ballinalee against Black and Tan reprisals in a three-hour gun battle. In County Mayo, large-scale guerrilla action did not break out until spring 1921, when two British forces were ambushed at Carrowkennedy and Tourmakeady. Elsewhere, fighting was more sporadic and less intense.\n", - "\n", - "In Belfast, the war had a character all of its own. The city had a Protestant and unionist majority and IRA actions were responded to with reprisals against the Catholic population, including killings (such as the McMahon killings) and the burning of many homes – as on Belfast's Bloody Sunday. The IRA in Belfast and the North generally, although involved in protecting the Catholic community from loyalists and state forces, undertook a retaliatory arson campaign against factories and commercial premises. The violence in Belfast alone, which continued until October 1922 (long after the truce in the rest of the country), claimed the lives of between 400 and 500 people.\n", - "\n", - "In April 1921, the IRA was again reorganised, in line with the Dáil's endorsement of its actions, along the lines of a regular army. Divisions were created based on region, with commanders being given responsibility, in theory, for large geographical areas. In practice, this had little effect on the localised nature of the guerrilla warfare.\n", - "\n", - "In May 1921, the IRA in Dublin attacked and burned the Custom House. The action was a serious setback as five members were killed and eighty captured.\n", - "\n", - "By the end of the war in July 1921, the IRA was hard-pressed by the deployment of more British troops into the most active areas and a chronic shortage of arms and ammunition. It has been estimated that the IRA had only about 3,000 rifles (mostly captured from the British) during the war, with a larger number of shotguns and pistols. An ambitious plan to buy arms from Italy in 1921 collapsed when the money did not reach the arms dealers. Towards the end of the war, some Thompson submachine guns were imported from the United States; however 450 of these were intercepted by the American authorities and the remainder only reached Ireland shortly before the Truce.\n", - "\n", - "By June 1921, Collins' assessment was that the IRA was within weeks, possibly even days, of collapse. It had few weapons or ammunition left. Moreover, almost 5,000 IRA men had been imprisoned or interned and over 500 killed. Collins and Mulcahy estimated that the number of effective guerrilla fighters was down to 2,000–3,000. However, in the summer of 1921, the war was abruptly ended.\n", - "\n", - "The British recruited hundreds of World War I veterans into the RIC and sent them to Ireland. Because there was initially a shortage of RIC uniforms, the veterans at first wore a combination of dark green RIC uniforms and khaki British Army uniforms, which inspired the nickname \"Black and Tans\". The brutality of the Black and Tans is now well-known, although the greatest violence attributed to the Crown's forces was often that of the Auxiliary Division of the Constabulary. One of the strongest critics of the Black and Tans was King George V who in May 1921 told Lady Margery Greenwood that \"he hated the idea of the Black and Tans.\"\n", - "\n", - "The IRA was also involved in the destruction of many stately homes in Munster. The Church of Ireland Gazette recorded numerous instances of Unionists and Loyalists being shot, burnt or forced from their homes during the early 1920s. In County Cork between 1920 and 1923 the IRA shot over 200 civilians of whom over 70 (or 36%) were Protestants: five times the percentage of Protestants in the civilian population. This was due to the historical inclination of Protestants towards loyalty to the United Kingdom. A convention of Irish Protestant Churches in Dublin in May 1922 signed a resolution placing \"on record\" that \"hostility to Protestants by reason of their religion has been almost, if not wholly, unknown in the twenty-six counties in which Protestants are in the minority.\"\n", - "\n", - "Many historic buildings in Ireland were destroyed during the war, most famously the Custom House in Dublin, which was disastrously attacked on de Valera's insistence, to the horror of the more militarily experienced Collins. As he feared, the destruction proved a pyrrhic victory for the Republic, with so many IRA men killed or captured that the IRA in Dublin suffered a severe blow.\n", - "\n", - "This was also a period of social upheaval in Ireland, with frequent strikes as well as other manifestations of class conflict. In this regard, the IRA acted to a large degree as an agent of social control and stability, driven by the need to preserve cross-class unity in the national struggle, and on occasion being used to break strikes.\n", - "\n", - "Assessments of the effectiveness of the IRA's campaign vary. They were never in a position to engage in conventional warfare. The political, military and financial costs of remaining in Ireland were higher than the British government was prepared to pay and this in a sense forced them into negotiations with the Irish political leaders. According to historian Michael Hopkinson, the guerrilla warfare \"was often courageous and effective\". Historian David Fitzpatrick observes, \"The guerrilla fighters...were vastly outnumbered by the forces of the Crown... The success of the Irish Volunteers in surviving so long is therefore noteworthy.\"\n", - "\n", - "Truce and treaty\n", - "\n", - "David Lloyd George, the British Prime Minister, at the time, found himself under increasing pressure (both internationally and from within the British Isles) to try to salvage something from the situation. This was a complete reversal on his earlier position. He had consistently referred to the IRA as a \"murder gang\" up until then. An unexpected olive branch came from King George V, who, in a speech in Belfast called for reconciliation on all sides, changed the mood and enabled the British and Irish Republican governments to agree to a truce. The Truce was agreed on 11 July 1921. On 8 July, de Valera met General Nevil Macready, the British commander in chief in Ireland and agreed terms. The IRA was to retain its arms and the British Army was to remain in barracks for the duration of peace negotiations. Many IRA officers interpreted the truce only as a temporary break in fighting. They continued to recruit and train volunteers, with the result that the IRA had increased its number to over 72,000 men by early 1922.\n", - "\n", - "Negotiations on an Anglo-Irish Treaty took place in late 1921 in London. The Irish delegation was led by Arthur Griffith and Michael Collins.\n", - "\n", - "The most contentious areas of the Treaty for the IRA were abolition of the Irish Republic declared in 1919, the status of the Irish Free State as a dominion in the British Commonwealth and the British retention of the so-called Treaty Ports on Ireland's south coast. These issues were the cause of a split in the IRA and ultimately, the Irish Civil War.\n", - "\n", - "Under the Government of Ireland Act 1920, Ireland was partitioned, creating Northern Ireland and Southern Ireland. Under the terms of the Anglo-Irish agreement of 6 December 1921, which ended the war (1919–21), Northern Ireland was given the option of withdrawing from the new state, the Irish Free State, and remaining part of the United Kingdom. The Northern Ireland parliament chose to do that. An Irish Boundary Commission was then set up to review the border.\n", - "\n", - "Irish leaders expected that it would so reduce Northern Ireland's size, by transferring nationalist areas to the Irish Free State, as to make it economically unviable. Partition was not by itself the key breaking point between pro- and anti-Treaty campaigners; both sides expected the Boundary Commission to greatly reduce Northern Ireland. Moreover, Michael Collins was planning a clandestine guerrilla campaign against the Northern state using the IRA. In early 1922, he sent IRA units to the border areas and sent arms to northern units. It was only afterwards, when partition was confirmed, that a united Ireland became the preserve of anti-Treaty Republicans.\n", - "\n", - "IRA and the Anglo-Irish Treaty\n", - "\n", - "The IRA leadership was deeply divided over the decision by the Dáil to ratify the Treaty. Despite the fact that Michael Collins – the de facto leader of the IRA – had negotiated the Treaty, many IRA officers were against it. Of the General Headquarters (GHQ) staff, nine members were in favour of the Treaty while four opposed it. The majority of the IRA rank-and-file were against the Treaty; in January–June 1922, their discontent developed into open defiance of the elected civilian Provisional government of Ireland.\n", - "\n", - "Both sides agreed that the IRA's allegiance was to the (elected) Dáil of the Irish Republic, but the anti-Treaty side argued that the decision of the Dáil to accept the Treaty (and set aside the Irish Republic) meant that the IRA no longer owed that body its allegiance. They called for the IRA to withdraw from the authority of the Dáil and to entrust the IRA Executive with control over the army. On 16 January, the first IRA division – the 2nd Southern Division led by Ernie O'Malley – repudiated the authority of the GHQ. A month later, on 18 February, Liam Forde, O/C of the IRA Mid-Limerick Brigade, issued a proclamation stating that: \"We no longer recognise the authority of the present head of the army, and renew our allegiance to the existing Irish Republic\". This was the first unit of the IRA to break with the pro-Treaty government.\n", - "\n", - "On 22 March, Rory O'Connor held what was to become an infamous press conference and declared that the IRA would no longer obey the Dáil as (he said) it had violated its Oath to uphold the Irish Republic. He went on to say that \"we repudiate the Dáil ... We will set up an Executive which will issue orders to the IRA all over the country.\" In reply to the question on whether this meant they intended to create a military dictatorship, O'Connor said: \"You can take it that way if you like.\"\n", - "\n", - "On 28 March, the (anti-Treaty) IRA Executive issued statement stating that Minister of Defence (Richard Mulcahy) and the Chief-of-Staff (Eoin O'Duffy) no longer exercised any control over the IRA. In addition, it ordered an end to the recruitment to the new military and police forces of the Provisional Government. Furthermore, it instructed all IRA units to reaffirm their allegiance to the Irish Republic on 2 April.\n", - "The stage was set for civil war over the Treaty.\n", - "\n", - "Civil War\n", - "\n", - "The pro-treaty IRA soon became the nucleus of the new (regular) Irish National Army created by Collins and Richard Mulcahy. British pressure, and tensions between the pro- and anti-Treaty factions of the IRA, led to a bloody civil war, ending in the defeat of the anti-Treaty faction. On 24 May 1923, Frank Aiken, the (anti-treaty) IRA Chief-of-Staff, called a cease-fire. Many left political activity altogether, but a minority continued to insist that the new Irish Free State, created by the \"illegitimate\" Treaty, was an illegitimate state. They asserted that their \"IRA Army Executive\" was the real government of a still-existing Irish Republic.

The CIRA is smaller and less active than the Real IRA, and there have been a number of splits within the organisation since the mid-2000s.\n", - "\n", - "Origins\n", - "The Continuity IRA has its origins in a split in the Provisional IRA. In September 1986, the Provisional IRA held a General Army Convention (GAC), the organisation's supreme decision-making body. It was the first GAC in 16 years. The meeting, which like all such meetings was secret, was convened to discuss among other resolutions, the articles of the Provisional IRA constitution which dealt with abstentionism, specifically its opposition to the taking of seats in Dáil Éireann (the parliament of the Republic of Ireland). The GAC passed motions (by the necessary two-thirds majority) allowing members of the Provisional IRA to discuss and debate the taking of parliamentary seats, and the removal of the ban on members of the organisation from supporting any successful republican candidate who took their seat in Dáil Éireann.\n", - "\n", - "The Provisional IRA convention delegates opposed to the change in the constitution claimed that the convention was gerrymandered \"by the creation of new IRA organisational structures for the convention, including the combinations of Sligo-Roscommon-Longford and Wicklow-Wexford-Waterford.\" The only IRA body that supported this viewpoint was the outgoing IRA Executive. Those members of the outgoing Executive who opposed the change comprised a quorum. They met, dismissed those in favour of the change, and set up a new Executive. They contacted Tom Maguire, who was a commander in the old IRA and had supported the Provisionals against the Official IRA (see Irish republican legitimatism), and asked him for support. Maguire had also been contacted by supporters of Gerry Adams, then president of Sinn Féin, and a supporter of the change in the Provisional IRA constitution.\n", - "\n", - "Maguire rejected Adams' supporters, supported the IRA Executive members opposed to the change, and named the new organisers the Continuity Army Council. In a 1986 statement, he rejected \"the legitimacy of an Army Council styling itself the Council of the Irish Republican Army which lends support to any person or organisation styling itself as Sinn Féin and prepared to enter the partition parliament of Leinster House.\" In 1987, Maguire described the \"Continuity Executive\" as the \"lawful Executive of the Irish Republican Army.\"\n", - "\n", - "Campaign\n", - "\n", - "Initially, the Continuity IRA did not reveal its existence, either in the form of press statements or paramilitary activity. Although the Garda Síochána had suspicions that the organisation existed, they were unsure of its name, labelling it the \"Irish National Republican Army\". On 21 January 1994, on the 75th anniversary of the First Dáil Éireann, Continuity IRA volunteers offered a \"final salute\" to Tom Maguire by firing over his grave, and a public statement and a photo were published in Saoirse Irish Freedom. In February 1994 it was reported that in previous months Gardaí had found arms dumps along the Cooley Peninsula in County Louth that did not belong to the Provisional IRA, and forensics tests determined had been used for firing practice recently.\n", - "\n", - "It was only after the Provisional IRA declared a ceasefire in 1994 that the Continuity IRA became active, announcing its intention to continue the campaign against British rule. The CIRA continues to oppose the Good Friday Agreement and, unlike the Provisional IRA (and the Real IRA in 1998), the CIRA has not announced a ceasefire or agreed to participate in weapons decommissioning—nor is there any evidence that it will. In the 18th Independent Monitoring Commission's report, the RIRA, the CIRA and the Irish National Liberation Army (INLA) were deemed a potential future threat. The CIRA was labelled \"active, dangerous and committed and... capable of a greater level of violent and other crime\". Like the RIRA and RIRA splinter group Óglaigh na hÉireann, it too sought funds for expansion. It is also known to have worked with the INLA.\n", - "\n", - "The CIRA has been involved in a number of bombing and shooting incidents. Targets of the CIRA have included the British military, the Northern Ireland police (both the Royal Ulster Constabulary and its successor the Police Service of Northern Ireland). Since the Good Friday Agreement in 1998 the CIRA, along with other paramilitaries opposing the ceasefire, have been involved with a countless number of punishment shootings and beatings. By 2005 the CIRA was believed to be an established presence on the island of Great Britain with the capability of launching attacks. A bomb defused in Dublin in December 2005 was believed to have been the work of the CIRA. In February 2006, the Independent Monitoring Commission (IMC) blamed the CIRA for planting four bombs in Northern Ireland during the final quarter of 2005, as well as several hoax bomb warnings. The IMC also blamed the CIRA for the killings of two former CIRA members in Belfast, who had stolen CIRA weapons and established a rival organisation.\n", - "\n", - "The CIRA continued to be active in both planning and undertaking attacks on the PSNI. The IMC said they tried to lure police into ambushes, while they have also taken to stoning and using petrol bombs. In addition, other assaults, robbery, tiger kidnapping, extortion, fuel laundering and smuggling were undertaken by the group. The CIRA also actively took part in recruiting and training members, including disgruntled former Provisional IRA members. As a result of this continued activity the IMC said the group remained \"a very serious threat\".\n", - "\n", - "On 10 March 2009 the CIRA claimed responsibility for the fatal shooting of a PSNI officer in Craigavon, County Armagh—the first police fatality in Northern Ireland since 1998. The officer was fatally shot by a sniper as he and a colleague investigated \"suspicious activity\" at a house nearby when a window was smashed by youths causing the occupant to phone the police. The PSNI officers responded to the emergency call, giving a CIRA sniper the chance to shoot and kill officer Stephen Carroll. Carroll was killed two days after the Real IRA's 2009 Massereene Barracks shooting at Massereene Barracks in Antrim. In a press interview with Republican Sinn Féin some days later, regarded by some to be the political wing of the Continuity IRA, Richard Walsh described the attacks as \"acts of war\".\n", - "\n", - "In 2013, the Continuity IRA's 'South Down Brigade' threatened a Traveller family in Newry and published a statement in the local newspaper. There were negotiations with community representatives and the CIRA announced the threat was lifted. It was believed the threat was issued after a Traveller feud which resulted in a pipe bomb attack in Bessbrook, near Newry. The Continuity IRA is believed to be strongest in the County Fermanagh – North County Armagh area (Craigavon, Armagh and Lurgan). It is believed to be behind a number of attacks such as pipe bombings, rocket attacks, gun attacks, and the PSNI claimed it orchestrated riots a number of times to lure police officers into areas such as Kilwilkie in Lurgan and Drumbeg in Craigavon in order to attack them. It also claimed the group orchestrated a riot during a security alert in Lurgan. The alert turned out to be a hoax.\n", - "\n", - "On Easter 2016, the Continuity IRA marched in paramilitary uniforms through North Lurgan, Co Armagh, without any hindrance from the PSNI who monitored the parade from a police helicopter.\n", - "\n", - "In July and August 2019 the CIRA carried out attempted bomb attacks on the PSNI in Craigavon, County Armagh and Wattlebridge, County Fermanagh.\n", - "\n", - "On 5 February 2020, a bomb planted by the CIRA was found by the PSNI in a lorry in Lurgan. The CIRA believed the lorry was going to be put on a North Channel ferry to Scotland in January 2020.\n", - "\n", - "Claim to legitimacy\n", - " Similar to the claim put forward by the Provisional IRA after its split from the Official IRA in 1969, the Continuity IRA claims to be the legitimate continuation of the original Irish Republican Army or Óglaigh na hÉireann. This argument is based on the view that the surviving anti-Treaty members of the Second Dáil delegated their \"authority\" to the IRA Army Council in 1938. As further justification for this claim, Tom Maguire, one of those anti-Treaty members of the Second Dáil, issued a statement in favour of the Continuity IRA, just as he had done in 1969 in favour of the Provisionals. J. Bowyer Bell, in his The Irish Troubles, describes Maguire's opinion in 1986: \"abstentionism was a basic tenet of republicanism, a moral issue of principle. Abstentionism gave the movement legitimacy, the right to wage war, to speak for a Republic all but established in the hearts of the people\". Maguire's stature was such that a delegation from Gerry Adams sought his support in 1986, but was rejected.Robert W. White, Ruairí Ó Brádaigh, The Life and Politics of an Irish Revolutionary, 2006, p. 310.\n", - "\n", - "Relationship to other organisations\n", - "These changes within the IRA were accompanied by changes on the political side and at the 1986 Sinn Féin Ard Fheis (party conference), which followed the IRA Convention, the party's policy of abstentionism, which forbade Sinn Féin elected representatives from taking seats in the Oireachtas, the parliament of the Republic, was dropped. On 2 November, the 628 delegates present cast their votes, the result being 429 to 161. The traditionalists, having lost at both conventions, walked out of the Mansion House, met that evening at the West County Hotel, and reformed as Republican Sinn Féin (RSF).\n", - "\n", - "According to a report in the Cork Examiner, the Continuity IRA's first chief of staff was Dáithí Ó Conaill, who also served as the first chairman of RSF from 1986 to 1987. The Continuity IRA and RSF perceive themselves as forming a \"true\" Republican Movement.\n", - "\n", - "Structure and status\n", - "The leadership of the Continuity IRA is believed to be based in the provinces of Munster and Ulster. It was alleged that its chief of staff was a Limerick man and that a number of other key members were from that county, until their expulsion. Dáithí Ó Conaill was the first chief of staff until 1991. In 2004 the United States (US) government believed the Continuity IRA consisted of fewer than fifty hardcore activists. In 2005, Irish Minister for Justice, Equality and Law Reform Michael McDowell told Dáil Éireann that the organisation had a maximum of 150 members.\n", - "\n", - "The CIRA is an illegal organisation under UK (section 11(1) of the Terrorism Act 2000) and ROI law due to the use of 'IRA' in the group's name, in a situation analogous to that of the Real Irish Republican Army (RIRA). Membership of the organisation is punishable by a sentence of up to ten years imprisonment under UK law. On 31 May 2001 Dermot Gannon became the first person to be convicted of membership of the CIRA solely on the word of a Garda Síochána chief superintendent. On 13 July 2004, the US government designated the CIRA as a 'Foreign Terrorist Organization'. This made it illegal for Americans to provide material support to the CIRA, requires US financial institutions to block the group's assets and denies alleged CIRA members visas into the US.\n", - "\n", - "External aid and arsenal\n", - "The US government suspects the Continuity IRA of having received funds and arms from supporters in the United States. Security sources in Ireland have expressed the suspicion that, in co-operation with the RIRA, the Continuity IRA may have acquired arms and materiel from the Balkans. They also suspect that the Continuity IRA arsenal contains some weapons that were taken from Provisional IRA arms dumps, including a few dozen rifles, machine guns, and pistols; a small amount of the explosive Semtex; and a few dozen detonators.\n", - "\n", - "Internal tension and splits\n", - "In 2005, several members of the CIRA, who were serving prison sentences in Portlaoise Prison for paramilitary activity, left the organisation. Some transferred to the INLA landing of the prison, but the majority of those who left are now independent and on E4 landing. The remaining CIRA prisoners have moved to D Wing. Supporters of the Continuity IRA leadership claim that this resulted from an internal disagreement, which although brought to a conclusion, was followed by some people leaving the organisation anyway. Supporters of the disaffected members established the Concerned Group for Republican Prisoners. Most of those who had left went back to the CIRA, or dissociated themselves from the CGRP, which is now defunct.\n", - "\n", - "In February 2006, the Independent Monitoring Commission claimed in a report on paramilitary activity that two groups, styling themselves as \"Óglaigh na hÉireann\" and \"Saoirse na hÉireann\", had been formed after a split in the Continuity IRA either in early 2006 or late 2005. The Óglaigh na hÉireann group was responsible for a number of pipe bomb attacks on the PSNI, bomb hoaxes, and robberies, the IMC also claimed the organisation was responsible for the killing of Andrew Burns on 12 February 2008 and was seeking to recruit former members of the RIRA. The Saoirse na hÉireann (SNH) group was composed of \"disaffected and largely young republicans\" and was responsible for a number of bomb hoaxes, two of which took place in September 2006. It was thought to have operated largely in republican areas of Belfast . The groups had apparently ceased operations by early 2009.\n", - "\n", - "In 2007, the Continuity IRA was responsible for shooting dead two of its members who had left and attempted to create their own organisation. Upon leaving the CIRA, they had allegedly taken a number of guns with them. The Continuity IRA is believed by Gardaí to have been involved in a number of gangland killings in Dublin and Limerick.\n", - "\n", - "In July 2010, members of a \"militant Northern-based faction within the CIRA\" led by a well-known member from south Londonderry claimed to have overthrown the leadership of the organisation. They also claimed that an Army Convention representing \"95 per cent of volunteers\" had unanimously elected a new 12-member Army Executive, which in turn appointed a new seven-member Army Council. The moves came as a result of dissatisfication with the southern-based leadership and the apparent winding-down of military operations. A senior source from RSF said: \"We would see them [the purported new leadership] as just another splinter group that has broken away.\" This organisation is referred to as the Real CIRA.\n", - "\n", - "In June 2011 CIRA member Liam Kenny was murdered, allegedly by drug dealers, at his home in Clondalkin, West Dublin. On 28 November 2011 an innocent man was mistakenly shot dead in retaliation for the murder of Liam Kenny. Limerick Real IRA volunteer Rose Lynch pleaded guilty to this murder at the Special Criminal Court and was sentenced to life imprisonment.\n", - "\n", - "In July 2012 the CIRA announced it had a new leadership after expelling members who had been working against the organisation.\n", - "\n", - "In April 2014 a former leading member of the Belfast Continuity IRA who had been expelled from the organisation, Tommy Crossan, was shot dead.\n", - "\n", - "In popular culture\n", - "The CIRA are depicted in RTÉ's TV series crime drama Love/Hate''.\n", - "\n", - "Notes\n", - "\n", - "References\n", - "\n", - " \n", - "Irish republican militant groups\n", - "Organised crime groups in Ireland\n", - "1986 establishments in Ireland \n", - "\n" - ] - } - ], - "source": [ - "for r in rs:\n", - " print(f\" **TEXT id-{r['id']}** \\n {r['text']} \\n\")\n", - "#" - ] - }, - { - "cell_type": "markdown", - "metadata": {}, - "source": [ - "As you can see in the above result, the closest match is the text itself that we used to search.

Each LanceDB +Enterprise API key corresponds to a unique principal, and each OpenID user has +a unique principal. + +All principals have an immutable ID which never changes, and is safe to include +in log files. For example, the API key +`sk_AAAQEAYEAUDAOCAJBIFQYDIOB4IBCEQTCQKRMFYYDENBWHA5DYPQ====` maps to the +principal ID `pk_aaaqeayeaudaocajbifqydiob4`. APIs such as `list_acls` will +return the principal ID, never the API key. + +OpenID principals also typically have a human-readable name associated with +them. For example, a principal might be named `bob@example.com` and might have +a principal ID of `8a004400-9443-4fab-9997-b9372a7ca8fd`. Whenever +possible, APIs will return the principal name for convenience. However, +principal names are mutable and can be changed by the identity provider. + +Here is an example of getting information about an API key: +```python +from lancedb.authz import Subject + +catalog = lancedb.connect_catalog("https://catalog.example.com", api_key=api_key) +principal = catalog.authz.get_principal(Subject.principal_api_key(api_key)) +print(f"Found principal {principal.principal_id}") +``` + +OpenID principals can be members of groups. Like principals, groups also have +IDs and human-readable names. It is not possible to modify group membership via +this API; it is managed by the OpenID identity provider. + +Here is an example of getting information about a group based on its name: +```python +from lancedb.authz import Subject + +catalog = lancedb.connect_catalog("https://catalog.example.com", api_key=api_key) +group = catalog.authz.get_group(Subject.group_name("Engineering")) +print(f"Found group {group.group_id} with name {group.group_name}") +``` + +Roles can contain either principals or groups. Unlike groups, they are managed +by the catalog, not the identity provider. Roles can also contain API key +principals. + +Here is an example of managing the `reader` role: +```python +from lancedb.authz import Subject + +catalog = lancedb.connect_catalog("https://catalog.example.com", api_key=api_key) +catalog.authz.add_role_binding(subject=Subject.principal_name("Alice"), role="reader") +``` +It may take a few milliseconds for changes to role bindings to become visible +to all clients. + +More subject types may be added in the future. + +### Objects + +An object is any resource in the system that we can attach authorization rules to. +The Python builders and Rust client share resource validation and wire encoding. +Methods also accept literal strings such as `table:tenant/db:public$events`; +malformed names for known resource types raise `ValueError` locally before a +request is sent. Unknown resource types are preserved for compatibility with +newer servers. + +Object types include: + +The System object, a singleton which represents the entire system. You can +refer to it as `Object.system()`. + +Database objects which represents specific databases. For example, +`Object.database("analytics")` represents the "analytics" database. + +Table objects which represent specific tables. For example, +`Object.table(database="analytics", name="events")` represents the "events" +table inside the "analytics" database. Tables are in the default namespace (which +is named "public") unless a specific namespace is given. + +Similarly, View objects represent specific views. For example, +`Object.view(database="analytics", name="recent_events")` represents the +"recent_events" view inside the "analytics" database. Views are in the default +namespace (which is named "public") unless a specific namespace is given. + +Secret objects identify named credentials, for example, +`Object.secret(database="analytics", name="api-key")`. Function objects identify +registered functions, for example, +`Object.function(database="analytics", name="caption")`. Both default to the +`public` namespace. Pass `namespace_path=["platform", "ml"]` to select a nested +namespace. These objects identify resources for ACL operations; a secret object +contains the credential's name, not its value. + +More object types may be added in the future. + +### Access control lists + +An access control list attaches a specific set of privileges to a specific +(subject, object) pair. So, for example, we might have an access control list +that gives `bob@example.com` the ability to read the foo table, that looks like +this: + +```python +from lancedb.authz import Object, Subject, Privilege + +catalog = lancedb.connect_catalog("https://catalog.example.com", api_key=api_key) +catalog.authz.add_acl( + object=Object.table(database="analytics", name="foo"), + subject=Subject.principal_name("bob@example.com"), + privilege=Privilege.SELECT, +) +``` + +Reading a table generally requires USAGE on its database and namespace, plus +SELECT on the table. Each object has at most one owner. + +OWNERSHIP is a special privilege which grants all the other privileges. By +default, the principal who created an object owns it. Only one subject can own +an object; granting OWNERSHIP to a new subject removes it from the previous +owner. OWNERSHIP cannot be deleted. + +To delegate secret or function creation, grant `CREATE_SECRET` or +`CREATE_FUNCTION` on the containing namespace. This preserves namespace ownership: + +```python +for privilege in [Privilege.CREATE_SECRET, Privilege.CREATE_FUNCTION]: + catalog.authz.add_acl( + object=Object.namespace(database="analytics", namespace_path=["public"]), + subject=Subject.role("developer"), + privilege=privilege, + ) +``` + +Both privileges also accept their string names in synchronous and asynchronous +ACL methods. + +By default, the `list_acls` function lists all the access control entries in +the system. By adding a function parameter, the output is filtered to just ACLs +matching that parameter. For example, this code lists all the ACLs for the +"reader" role: + +```python +from lancedb.authz import Subject + +catalog = lancedb.connect_catalog("https://catalog.example.com", api_key=api_key) +for entry in catalog.authz.list_acls(subject=Subject.role("reader")): + print(entry) +``` + +Or, when using the async API: +```python +catalog = await lancedb.connect_catalog_async(endpoint, api_key=api_key) +async for entry in catalog.authz.list_acls(subject=Subject.role("reader")): + print(entry) +``` + +## Remote SQL + +Submit SQL against a remote LanceDB database through the connection. +The connected database and `default_namespace_path=["public"]` are used for +unqualified tables. Fully qualified references can still query other databases +and namespaces available to the same deployment. `execute_query` returns a +reader as soon as its initial result stream is available. `execute_query_async` +returns a query handle immediately; use it to inspect progress, open a reader, +or cancel the query. The SQL client is initialized by the first query and +retained for the lifetime of the remote connection. Query ids are random, +connection-scoped references rather than encoded SQL or durable resume tokens: + +```python +import lancedb + +db = lancedb.connect( + "db://analytics", + api_key="ldb_...", + host_override="https://api.example.com", + sql_host_override="grpc+tls://sql.example.com:10026", +) +reader = db.execute_query( + """ + SELECT events.id, accounts.name + FROM analytics.public.events AS events + JOIN users.public.accounts AS accounts ON events.user_id = accounts.id + """, + default_namespace_path=["public"], +) +for batch in reader: + print(batch.num_rows) + +query = db.execute_query_async("SELECT * FROM events") +print(query.id) +print(query.describe().status) +for batch in query.reader(): + print(batch.num_rows) + +# Values bind to $1 / $name placeholders and travel as Arrow, so a float32 +# stays a float32 and a vector stays a compact fixed-size list: +import numpy as np + +reader = db.execute_query( + "SELECT id FROM docs ORDER BY distance(vector, $vector) LIMIT $k", + parameters={"vector": np.random.rand(768).astype(np.float32), "k": 10}, +) + +# The async connection exposes the same lifecycle without blocking: +# async_db = await lancedb.connect_async( +# "db://analytics", +# api_key="ldb_...", +# host_override="https://api.example.com", +# sql_host_override="grpc+tls://sql.example.com:10026", +# ) +# reader = await async_db.execute_query("SELECT * FROM events") +# query = await async_db.execute_query_async("SELECT * FROM events") +# description = await async_db.describe_query(query.id) +# async for batch in await query.reader(): +# print(batch.num_rows) +# await query.cancel() +``` + +## Namespaces (Synchronous) + +A namespace-backed connection resolves tables through a +[Lance namespace](https://lance-format.github.io/lance-namespace/) service instead of +listing a storage directory. + +::: lancedb.connect_namespace + +::: lancedb.namespace.LanceNamespaceDBConnection + ## Tables (Synchronous) ::: lancedb.table.Table +::: lancedb.table.FragmentStatistics + +::: lancedb.table.FragmentSummaryStats + +::: lancedb.table.TableStatistics + +::: lancedb.table.Tags + +::: lancedb.table.Branches + +::: lancedb.RTEWriteSpec + +## Functions and Jobs + +::: lancedb.functions.FunctionArtifact + +::: lancedb.functions.FunctionParameter + +::: lancedb.functions.FunctionResultField + +::: lancedb.functions.FunctionOutput + +::: lancedb.functions.FunctionSignature + +::: lancedb.functions.PythonEnvironmentSpec + +::: lancedb.functions.udf + +::: lancedb.functions.UdfDefinition + +::: lancedb.secrets.EnvVarSecret + +::: lancedb.secrets.SecretInfo + +::: lancedb.functions.FunctionRegistrationRequest + +::: lancedb.functions.FunctionArtifactRequest + +::: lancedb.functions.FunctionArtifactContent + +::: lancedb.functions.PythonAdapterSpec + +::: lancedb.functions.FunctionImage + +::: lancedb.functions.FunctionVersion + +::: lancedb.functions.PythonRuntimeSpec + +::: lancedb.functions.FunctionVersionRef + +::: lancedb.functions.ApplicationInput + +::: lancedb.functions.FunctionApplication + +::: lancedb.functions.InputBinding + +::: lancedb.functions.OutputMapping + +::: lancedb.functions.AssignmentMapping + +::: lancedb.functions.FunctionBinding + +::: lancedb.functions.RefreshColumnResult + +::: lancedb.FunctionErrors + +::: lancedb.FunctionErrorRecord + +::: lancedb.FunctionErrorFragment + +::: lancedb.job.Job + +::: lancedb.job.AsyncJob + +::: lancedb.job.JobInfo + +::: lancedb.job.JobDescription + +::: lancedb.job.JobFailureInfo + +::: lancedb.sql.Query + +::: lancedb.sql.AsyncQuery + +::: lancedb.sql.QueryDescription + +::: lancedb.sql.QueryParameters + +## Materialized Views (Synchronous) + +On Cloud and Enterprise, creation accepts `auto_refresh_enabled` and +`auto_refresh_interval_seconds`: + +```python +view = db.create_materialized_view( + "recent_orders", + "orders", + auto_refresh_enabled=True, + auto_refresh_interval_seconds=300, +) +``` + +Omit `auto_refresh_interval_seconds` to let the server determine when to refresh. +These options also apply to asynchronous creation and creation jobs.

Some of the rerankers that are available in LanceDB are: - -| Reranker | Description | Supported Query Types | -| --- | --- | --- | -| `LinearCombinationReranker` | Reranks search results based on a linear combination of FTS and vector search scores | Hybrid | -| `CohereReranker` | Uses cohere Reranker API to rerank results | Vector, FTS, Hybrid | -| `CrossEncoderReranker` | Uses a cross-encoder model to rerank search results | Vector, FTS, Hybrid | -| `ColbertReranker` | Uses a colbert model to rerank search results | Vector, FTS, Hybrid | -| `OpenaiReranker`(Experimental) | Uses OpenAI's chat model to rerank search results | Vector, FTS, Hybrid | -| `VoyageAIReranker` | Uses voyageai Reranker API to rerank results | Vector, FTS, Hybrid | - - -## Using a Reranker -Using rerankers is optional for vector and FTS. However, for hybrid search, rerankers are required. To use a reranker, you need to create an instance of the reranker and pass it to the `rerank` method of the query builder: - -```python -import lancedb -from lancedb.embeddings import get_registry -from lancedb.pydantic import LanceModel, Vector -from lancedb.rerankers import CohereReranker - -embedder = get_registry().get("sentence-transformers").create() -db = lancedb.connect("~/.lancedb") - -class Schema(LanceModel): - text: str = embedder.SourceField() - vector: Vector(embedder.ndims()) = embedder.VectorField() - -data = [ - {"text": "hello world"}, - {"text": "goodbye world"} - ] -tbl = db.create_table("test", data) -reranker = CohereReranker(api_key="your_api_key") - -# Run vector search with a reranker -result = tbl.search("hello").rerank(reranker).to_list() - -# Run FTS search with a reranker -result = tbl.search("hello", query_type="fts").rerank(reranker).to_list() - -# Run hybrid search with a reranker -tbl.create_fts_index("text") -result = tbl.search("hello", query_type="hybrid").rerank(reranker).to_list() -``` - -### Multi-vector reranking -Most rerankers support reranking based on multiple vectors. To rerank based on multiple vectors, you can pass a list of vectors to the `rerank` method. Here's an example of how to rerank based on multiple vector columns using the `CrossEncoderReranker`: - -```python -from lancedb.rerankers import CrossEncoderReranker - -reranker = CrossEncoderReranker() - -query = "hello" - -res1 = table.search(query, vector_column_name="vector").limit(3) -res2 = table.search(query, vector_column_name="text_vector").limit(3) -res3 = table.search(query, vector_column_name="meta_vector").limit(3) - -reranked = reranker.rerank_multivector([res1, res2, res3], deduplicate=True) -``` - -## Available Rerankers -LanceDB comes with the following built-in rerankers: - -- [Cohere Reranker](./cohere.md) -- [Cross Encoder Reranker](./cross_encoder.md) -- [ColBERT Reranker](./colbert.md) -- [OpenAI Reranker](./openai.md) -- [Linear Combination Reranker](./linear_combination.md) -- [Jina Reranker](./jina.md) -- [AnswerDotAI Rerankers](./answerdotai.md) -- [Reciprocal Rank Fusion Reranker](./rrf.md) -- [VoyageAI Reranker](./voyageai.md) - -## Creating Custom Rerankers - -LanceDB also you to create custom rerankers by extending the base `Reranker` class. The custom reranker should implement the `rerank` method that takes a list of search results and returns a reranked list of search results.

Download the multimodal dataset {#1-download-the-multimodal-dataset} + +From a new project directory, download the JSON file and portraits: + +```bash +mkdir -p data/img + +BASE_URL="https://docs.lancedb.com/static/assets/tutorials/build-with-ai-agents/camelot/data" +curl -fsSL "$BASE_URL/camelot.json" -o data/camelot.json + +for image in \ + arthur.jpg \ + guinevere.jpg \ + merlin.jpg \ + mordred.jpg \ + sir_galahad.jpg \ + sir_gawain.jpg \ + sir_lancelot.jpg \ + sir_percival.jpg +do + curl -fsSL "$BASE_URL/img/$image" -o "data/img/$image" +done +``` + +Each JSON record has this shape: + +```json +{ + "id": 2, + "name": "Merlin", + "role": "Wizard and Advisor", + "description": "A powerful wizard and prophet who mentors Arthur.", + "stats": { + "strength": 2, + "courage": 4, + "magic": 5, + "wisdom": 5 + }, + "img": "data/img/merlin.jpg" +} +``` + +JSON input may have missing fields, unexpected fields, or values of the wrong +type. The LanceDB plugin tells the agent to validate each record with strict +Pydantic models before writing it. + +After the agent writes the pipeline, inspect the schema, batching, and write +path rather than assuming it followed the plugin's guidance correctly. + +### 2\. Prompt your agent to build the pipeline {#2-prompt-your-agent-to-build-the-pipeline} + +Install the Python packages used by the example: + +```bash icon="terminal" +uv init +uv add lancedb pyarrow pydantic +``` + +If you're using LanceDB Enterprise, ask the agent to ingest into an Enterprise table, +provide the relevant environment variables for connecting to your Enterprise deployment +in a local `.env` file, and point the agent to it. + +```text .env +LANCEDB_URI=db://your_project_name +LANCEDB_API_KEY=your_api_key_here +LANCEDB_REGION=us-east-1 +LANCEDB_HOST_OVERRIDE=https://your-enterprise-endpoint.com +``` + +If you're using LanceDB OSS, no connection settings are required, as it runs as an +embedded retrieval library. A simple prompt like this should work: + +```text Agent prompt +# If using OSS +Use the lancedb plugin to ingest the dataset in `data/` into a LanceDB +OSS table. + +# If using enterprise +Use the lancedb plugin to ingest the dataset in `data/` into a LanceDB +Enterprise table using the connection information in `.env`. +``` + +Because the plugin is registered with the agent's own plugin system, the agent +should pick it up on its own once you restart the session. If it does not, +simply ask it to use the `lancedb` plugin in the prompt, as shown above. + +That should be enough! The agent will create `ingest_multimodal.py`, or similar. +The following sections inspect the script to verify that it follows the plugin's guidance. + +#### Data validation {#data-validation} + +The plugin encourages the agent to validate each record with Pydantic before writing it. +The agent should ideally define a schema for the table and a nested schema for the +`stats` field. + + + {PyCamelotSchema} + + +In this case, our agent correctly defined `Character` and `Stats` Pydantic models +and validated the JSON before adding it to the table. + +#### Batched ingestion {#batched-ingestion} + +Naively calling `table.add()` once per row is slow, and is considered an anti-pattern +in LanceDB. The plugin encourages the agent to collect incoming rows into batches and +write them with a single `table.add()` call. When you use the plugin, the agent should +produce something like this: + + + {PyCamelotBatches} + + +The script calls `Character.model_validate(...)` before adding a record to the +batch. If validation fails, that batch is never written. The function yields up +to `batch_size` rows at a time, providing an iterable of batches for the ingestion step, +shown next. + +#### Table maintenance {#table-maintenance} +For LanceDB OSS, the plugin instructs the agent to call +`table.optimize()` after the ingestion loop. This compacts small fragments, cleans up +old versions according to the retention policy, and incorporates new data into indexes. + + + {PyCamelotOssIngestion} + + +If you're using LanceDB Enterprise, the plugin mentions that this step is not needed +because LanceDB Enterprise handles maintenance automatically. + + + +This example dataset has only eight rows, so the default batch size writes it in +one call. Larger inputs should still avoid single-row write commits. + + +### 3\. Run the OSS pipeline {#3-run-the-oss-pipeline} + +```bash +uv run python ingest_multimodal.py +``` + +The table now contains the validated character records and their JPEG bytes. +Here are the first three rows: + +| Image | Character | Role | +| --- | --- | --- | +| King Arthur | King Arthur | King of Camelot | +| Merlin | Merlin | Wizard and Advisor | +| Queen Guinevere | Queen Guinevere | Queen of Camelot | + +Once your pipeline works, you can [run experiments on branches](/agent-branch-experiments) +to try new embedding models, parsers, or search settings without touching `main`. + +### Takeaways {#takeaways} + +The example in this tutorial was small, but similar ideas apply to other workflows, too. +Give the agent the data source, the constraints it must respect, and the +artifacts it should return. + +The plugin supplies LanceDB-specific guidance, but it's the user's responsibility to +ensure the output makes sense for the application. + +### Try the plugin with your own dataset {#try-the-plugin-with-your-own-dataset} + +The plugin shown in this tutorial should generalize reasonably well to other use cases. +If you find any issues, open [an issue](https://github.com/lancedb/lancedb-agent-plugins/issues) +on GitHub, clearly describing the intended behavior. + +You can choose OSS or Enterprise based on how the work will run: + +Start with [LanceDB OSS](/quickstart) during the early stages of a project +when an agent is helping you prototype, +explore a dataset, or run small workflows on a subset of the data. The application owns +the storage and lifecycle work, so ask the agent to validate inputs, write in +batches, and it will include table maintenance operations such as `optimize()` +where appropriate. + +Choose [LanceDB Enterprise](/enterprise) when the resulting table becomes +shared production infrastructure, and the workload needs distributed capacity, +private deployment, or platform-managed operations. The data format and the core +table API stay the same, so the pipeline's table and search code carries over: +the agent connects to a remote `db://` table, leaves maintenance to the +deployment instead of calling `optimize()`, and submits long-running work as +jobs. See [Moving to LanceDB Enterprise](/basics/sdk#moving-to-enterprise). + +## What agents are good at here {#workflows} + +The walkthrough above is one pattern. The other has its own tutorial. + + + + Isolate agent-driven experiments on a branch, evaluate them on a fixed test + set, and promote only the winner. + + + +It is the more interesting pattern. [Branches](/management/table#versioning) +give an agent somewhere to be wrong safely: it can rewrite a schema, recompute a +column, or try three embedding models without touching `main`, and you keep only +what measured better. diff --git a/docs/web/basics/catalog.mdx b/docs/web/basics/catalog.mdx new file mode 100644 index 000000000..c6950b9de --- /dev/null +++ b/docs/web/basics/catalog.mdx @@ -0,0 +1,66 @@ +--- +title: "Lance Catalog" +sidebarTitle: "Lance Catalog" +description: "Organize, find and control access to your data in LanceDB." +icon: sitemap +keywords: ["catalog", "namespace", "hierarchy", "governance", "database", "table", "view"] +--- + +## Catalog overview {#catalog} + +A catalog keeps track of named data objects, such as tables and views, so +applications can discover and access them.

Use this guide to pick the right fit for your workload. + +## Choosing a backend {#choosing} + +![](/static/assets/images/storage/lancedb_storage_tradeoffs.png) + +When architecting your system, ask yourself: + +- **Latency**: How fast do I need results? What do the p50 and p95 look like? +- **Scalability**: Can I scale data volume and QPS easily? +- **Cost**: What is the all-in cost of storage plus serving? +- **Reliability/Availability**: How will replication and disaster recovery work? + +### Comparison {#comparison} + +Below is a high-level comparison ordered from lowest cost to lowest latency. + +### 1\. Object storage (S3, GCS, Azure Blob) {#1-object-storage-s3-gcs-azure-blob} +- **Latency**: Highest; expect hundreds of milliseconds and higher p95. +- **Scalability**: Effectively unlimited storage; QPS bound by concurrency limits. +- **Cost**: Lowest overall. +- **Reliability/Availability**: Highly available, backed by cloud SLAs. + +LanceDB separates storage and compute and writes immutable fragments, making it a strong fit for stateless, horizontally scalable deployments. + + +**Concurrent writers on S3** + +S3 and S3 Express now support atomic writes natively, so LanceDB handles concurrent writers against the same table out-of-the-box: no external commit coordinator is required. Bucket-level [server-side encryption with KMS](/storage/configuration#server-side-encryption-with-kms) and [S3 Express One Zone](/storage/configuration#s3-express) are also supported on this tier. + + +### 2\. File storage (EFS, GCS Filestore, Azure File) {#2-file-storage-efs-gcs-filestore-azure-file} +- **Latency**: Better than object storage; p95 under ~<100ms is typical. +- **Scalability**: High, but limited by provisioned IOPS per volume. +- **Cost**: More than object storage but cheaper than in-memory options; cold data can tier down automatically. +- **Reliability/Availability**: Highly available; replication/backup must be managed separately. + +Keep a copy of data in object storage for disaster recovery. If zero downtime is required, provision a second network file system with replicated data. + +### 3\. Third-party storage (e.g., MinIO, WekaFS) {#3-third-party-storage-e-g--minio-wekafs} + +- **Latency**: Similar to EFS; typically under <100ms. +- **Scalability**: Determined by the chosen vendor’s cluster sizing. +- **Cost**: Higher than S3; may edge above EFS at larger scales. +- **Reliability/Availability**: Shareable across many nodes; replication depends on vendor capabilities. + +### 4\. Block storage (EBS, GCP Persistent Disk, Azure Managed Disk) {#4-block-storage-ebs-gcp-persistent-disk-azure-managed-disk} +- **Latency**: Near-local performance; often <30ms. +- **Scalability**: Not shareable across instances; shard or copy data when scaling. +- **Cost**: Higher than networked file systems, plus potential I/O charges. +- **Reliability/Availability**: Persists through instance restarts; backups and sharding must be managed. + +### 5\. Local storage (SSD, NVMe) {#5-local-storage-ssd-nvme} +- **Latency**: Fastest; p95 often under <10ms. +- **Scalability**: Hard to scale in cloud environments; requires sharding or additional copies for higher QPS. +- **Cost**: Highest; tightly coupling compute and storage makes horizontal scaling difficult. +- **Reliability/Availability**: Data is tied to the instance; backups must be rigorous. + +Use local disk only when you need extremely low latency and are comfortable owning the operational overhead. + +### File-format choices that interact with the backend {#file-format-choices} + +A few `storage_options` keys shape new tables in ways that depend on the backend you picked above.

The position of an embedding in vector space captures the semantics of +the data, so vectors that are close to each other are considered similar. + +LanceDB provides an embedding function registry in OSS as well as its Enterprise versions +([see below](#embeddings-in-lancedb-enterprise)) +that automatically generates vector embeddings during data ingestion. Query text is embedded +automatically too, in the client, for local and Enterprise tables alike, with SDK-specific query +ergonomics. The API abstracts +embedding generation, allowing you to focus on your application logic. + +## Embedding Registry {#embedding-registry} + +You can get a supported embedding function from the registry, and then use it in your table schema. +Once configured, the embedding function will automatically generate embeddings when you insert data +into the table. Query-time behavior depends on SDK: Python/TypeScript can query with text directly, +while Rust examples typically compute query embeddings explicitly before vector search. + +In the Rust examples, replace `your-openai-api-key` with your OpenAI API key. In +application code, load credentials from environment variables or a secrets manager. + + + + {PyOpenaiEmbeddings} + + + + {TsOpenaiEmbeddings} + + + + {RsOpenaiEmbeddings} + + + +### Using an embedding function {#using-an-embedding-function} + +Create an embedding function before you attach it to table or schema metadata. Python and TypeScript fetch +provider implementations from the embedding registry, while Rust constructs the provider embedding function +directly and registers it on the connection before using it in an `EmbeddingDefinition`. + + + + {PyCreateEmbeddingFunction} + + + + {TsCreateEmbeddingFunction} + + + + {RsCreateEmbeddingFunction} + + + +Provider configuration is SDK-specific, so copy the option names from the provider page for the SDK you use. +For example, the OpenAI model is selected with `name` in Python, `model` in TypeScript, and the model argument +to `OpenAIEmbeddingFunction::new_with_model` in Rust. + +| Concept | Python | TypeScript | Rust | +| --- | --- | --- | --- | +| Model | `name="text-embedding-3-small"` | `{ model: "text-embedding-3-small" }` | `new_with_model(api_key, "text-embedding-3-small")` | +| Retry count | `max_retries=7` | Provider/client-specific | Provider/client-specific | +| API key | `api_key="..."`, environment variables, or `$var:` | `apiKey: "..."`, environment variables, or `$var:` | Constructor argument or environment variable | +| Device | Provider-specific, for example `device="cuda"` | Provider-specific | Provider-specific | + +When ingesting data with an embedding definition, LanceDB only computes the vector column if that +column is missing from the incoming batch or present but entirely null. If you provide any non-null +values in the vector column, LanceDB treats the column as user-supplied and does not backfill the +remaining rows in that batch. + +For reusable runtime configuration, the registry also supports `$var:` placeholders in embedding-function config. +This is useful for provider secrets and environment-specific settings in Python and TypeScript. + +- Python uses `registry.set_var(...)`. +- TypeScript uses `registry.setVar(...)`. +- You can provide a fallback with `$var:name:default`. +- Sensitive values such as API keys should be passed through registry variables instead of hardcoding them in config. + + + + {PyRegisterSecret} + + + + {TsRegisterSecret} + + + +For non-sensitive settings such as inference device selection, you can also use a default fallback: + + + + {PyRegisterDevice} + + + + {TsRegisterModelFallback} + + + +Find the full list of arguments for each provider in the [integrations](/integrations/embedding) section. + +### Trusting remote code and custom endpoints {#trusting-remote-code-and-custom-endpoints} + +In Python, the embedding definition is stored in the table, so anyone who can write to the table can change it. +To keep a table from running code or sending data where you didn't intend, two kinds of settings are only honored +when this process has approved them: + +- `trust_remote_code=True`, which runs code from the model's Hugging Face repository. +- Custom endpoints such as OpenAI `base_url`, Ollama `host`, or watsonx `url`, which receive your data and API keys. + +Embedding functions you create in the current process are approved automatically. When you open a table in a new +process, approve these settings explicitly before computing embeddings: + +```python +from lancedb.embeddings import get_registry + +registry = get_registry() +# Pinning a commit hash is recommended, since the code at a branch can change. +registry.allow_remote_code("nomic-ai/nomic-embed-text-v1.5", revision="") +registry.allow_endpoint("http://my-ollama-host:11434") +``` + +Until then, computing embeddings raises `UntrustedEmbeddingConfigError`. Other operations on the table still work. + +## Multiple embedding columns {#multiple-embedding-columns} + +A single table can include more than one embedding definition when you want to store multiple semantic views +of the same data, or generate embeddings from different source columns. In practice, each embedding definition +maps one source column to one vector column, and the table schema can contain multiple such pairs. + +The exact setup differs by SDK, but the underlying pattern is the same: define a distinct source/vector pair +for each embedding function you want applied during ingest. + +In TypeScript, automatic query embedding currently uses the first embedding function stored in the +table metadata. If a table has multiple embedding definitions and you need to query a specific vector +column, compute the query embedding explicitly and pass the vector to the search builder. + +## Embedding model providers {#embedding-model-providers} + +LanceDB supports most popular embedding providers. + +### Text embeddings {#text-embeddings} + +| Provider | Model ID | Default Model | +|----------|----------|---------------| +| OpenAI | `openai` | `text-embedding-ada-002` | +| Sentence Transformers | `sentence-transformers` | `all-MiniLM-L6-v2` | +| Hugging Face | `huggingface` | `colbert-ir/colbertv2.0` | +| Cohere | `cohere` | `embed-english-v3.0` | +| ... | ... | ... | + +### Multimodal embedding {#multimodal-embedding} + +| Provider | Model ID | Supported Inputs | +|----------|----------|------------------| +| OpenCLIP | `open-clip` | Text, Images | +| ImageBind | `imagebind` | Text, Images, Audio, Video | +| ... | ... | ... | + +You can find all supported embedding models in the [integrations](/integrations/embedding) section. + +## Embeddings in LanceDB Enterprise {#embeddings-in-lancedb-enterprise} +Enterprise + +In LanceDB Enterprise, embedding generation during data ingestion is client-side and the resulting vectors are +stored on the remote table. + + +The Enterprise server does not currently generate embeddings from query text on its own. Any automatic +query-time embedding happens on the client side. + + +### How string queries are interpreted {#how-string-queries-are-interpreted} + +For the Python remote client, `table.search("hello")` can take two different paths: + +- If the selected vector column has embedding metadata + (i.e., the table schema stores the source-column, vector-column, and + embedding-function mapping created from fields like `SourceField()` and + `VectorField()` during table creation), then the embeddings are computed in the Python client process. + The client uses the same local LanceDB embedding registry used by OSS tables to + reconstruct the embedding function from schema metadata, compute the query vector in + the client process, and send that vector to Enterprise for search. + ```python + result = table.search("hello").limit(1).to_list() + # The Python client computes the query embedding locally, then sends a vector search. + ``` +- If the table does not have embedding metadata for that search, `table.search("hello")` in `auto` mode is + treated as an FTS query instead. + ```python + result = table.search("hello").limit(5).to_list() + # In auto mode this is treated as an FTS query, not a vector query. + ``` + +If you want explicit vector or hybrid behavior and the client cannot resolve an embedding function from the +table metadata, generate the query embedding yourself and pass the vector directly. + +TypeScript has a similar string-query distinction in `auto` mode: if no embedding providers have been +registered in the process, `search("text")` falls back to FTS. Once an embedding provider has been +imported and registered, the client expects table embedding metadata for automatic vector search and +raises an error if the table has none. + +The manual query-embedding flow below works across Enterprise SDKs and is an explicit path you can use when you +want full control over query-time behavior. + + + + {PyManualQuerySearch} + + + + {TsManualQuerySearch} + + + + {RsManualQuerySearch} + + + +## Custom Embedding Functions {#custom-embedding-functions} + +You can always implement your own embedding function: +- Python/TypeScript: subclass `TextEmbeddingFunction` (text) or `EmbeddingFunction` (multimodal). +- Rust: implement the `EmbeddingFunction` trait. + + + + {PyEmbeddingFunction} + + + + {TsEmbeddingFunction} + + + + {RsEmbeddingFunction} + + diff --git a/docs/web/embedding/quickstart.mdx b/docs/web/embedding/quickstart.mdx new file mode 100644 index 000000000..bcaf90f6f --- /dev/null +++ b/docs/web/embedding/quickstart.mdx @@ -0,0 +1,155 @@ +--- +title: "Embeddings: Quickstart" +sidebarTitle: "Quickstart" +description: "Quickstart guide for generating and working with embeddings." +icon: "rocket" +--- + +import { + TsQuickstartConnect, + TsQuickstartCreateTable, + TsQuickstartImports, + TsQuickstartInitModel, + TsQuickstartQuery, + TsQuickstartSchema, +} from '/snippets/sentence-transformers.mdx'; + +LanceDB will automatically vectorize the data both at ingestion and query time.

It +leaves the rest alone, so calling it twice is not twice the work, and appending +rows means the next refresh handles only the new ones. + +**Computed values update when you refresh.** If a column derives from `price` and a row's +`price` is later updated, the derived value keeps its old value until the next +refresh recomputes it.

Lance looks under the default platform data directory for `lance/language_models`, or you can set `LANCE_LANGUAGE_MODEL_HOME` to point to another model root. For example, `jieba/default` is resolved under `/jieba/default/...`. For a table in LanceDB Enterprise, the files must be present where the deployment builds and queries the index, so ask its administrator whether they are installed. + +`language` is used by token filters, not by the base tokenizer. Stemming and language-specific stop-word removal support Arabic, Danish, Dutch, English, Finnish, French, German, Greek, Hungarian, Italian, Norwegian, Portuguese, Romanian, Russian, Spanish, Swedish, Tamil, and Turkish. The ICU tokenizer uses a combined multilingual stop-word list.

In filtered workloads, HNSW-backed IVF indexes such as `IVF_HNSW_FLAT` and `IVF_HNSW_SQ` can show higher latency variance. + + +## Understanding Vector Indexes + +LanceDB offers two vector indexes, which can be created on any numeric Lance dataset: +**Inverted File (IVF)** and **Hierarchical Navigable Small World (HNSW)**. + +### IVF + +The **Inverted File Index (IVF)** accelerates ANN searches by drastically reducing the search space. The index consists of +a small set of *centroids* corresponding to an approximate solution to the +[$k$-means clustering](https://en.wikipedia.org/wiki/K-means_clustering) problem. +Each vector remembers its nearest centroid, and each centroid remembers its associated set of vectors, +called its *partition*. + + IVF vector-space partitioning + + +At query time, we can compare the queried vector to the smaller set of *centroids* (as opposed to the entire dataset) +for a closest match, then run a brute-force comparison against its resulting partition. This technique quickly prunes a large search space, +giving an approximate ANN result. + +However, observe that a queried vector may lie near the boundary of $2$ or more partitions; thus, the true nearest neighbors are scattered across several different partitions. + To address this, LanceDB exposes the `nprobes` parameter, which specifies the number of partitions searched. +A high `nprobes` parameter will yield more accurate results at slightly higher runtime. + + + IVF vector-space partitioning + + +### HNSW +**Hierarchical Navigable Small World (HNSW)** constructs a layered graph hierarchy on the vector set, with edges representing distances. +We can visualize an HNSW index as a vertical stack of graphs, with the top layer having very few edges and +each other layer having a multiplicative factor more edges than the layer above it. + +High layers of a HNSW hierarchy represent sparse, higher-distance networks, and lower layers represent finer, lower-distance networks. +To query a vector $q$, the index proceeds iteratively through layers, first finding $q$'s nearest neighbor in the graph, then proceeding recursively +through the induced subhierarchy until the lowest layer is reached. + + + HNSW layered graph hierarchy + + +To visualize this process, imagine that you must drive your car from San Francisco to a specific house in Boston. Initially, you must first drive thousands of miles +on the interstate freeway I-90 E. Eventually, you merge onto the Massachusetts Turnpike, the center +of the greater Boston highway system. From there, you use a series of increasingly smaller, narrower roads within the city (Charles River Bridge, St. Paul St, +Thatcher St) before finally reaching the house. + +A key observation is that you must initially travel far distances through long-distance road networks +(the interstate freeway system), before proceeding to finer and finer road networks (greater Boston highway system, central Brookline neighborhood connectors) before finally reaching +your destination. This iterative series of road networks mimics the layered graph traversals performed by a HNSW query. + +**IVF + HNSW** + +In LanceDB, HNSW is not exposed as a top-level vector index. Instead, it's available as a substructure which +further indexes the selected vectors inside each IVF partition. +This combines the scalability of IVF with the high recall of HNSW. +LanceDB supports IVF-HNSW-based quantized indexes `IVF_HNSW_FLAT`, `IVF_HNSW_PQ`, and `IVF_HNSW_SQ`; a deployment builds only `IVF_HNSW_SQ`. + + + +## Using Vector Indexes +Learn how to configure, build, and search LanceDB vector indexes, including build and search time parameters, asynchronous objects, and several examples. + +### Configuration + +#### Build-time Parameters + +| Parameter | Description | +| :--- | :--- | +| `distance_type` | Default is `l2`, others available are `cosine` and `dot`. +| `num_partitions` | The number of IVF partitions constructed (corresponds to the $k$ in $k$-means clustering). This takes precedence over `target_partition_size` if both are set. | +| `target_partition_size` | An alternative IVF sizing knob that derives the partition count by setting the number of rows per partition. `num_partitions` takes precedence over `target_partition_size` if both are set. If neither is set the number of partitions is automatically calculated based on the number of rows and the index type. | +| `num_sub_vectors` | Applies to `IVF_PQ`; defaults to `dimension // 16` (or `dimension // 8` if not a multiple of 16). Larger values produce better recall and slower search. | +| `max_iterations` | Maximum number of k-means training iterations, for every IVF/HNSW index type. Default `50`. Increase for larger datasets or to improve training quality. | +| `sample_rate` | Number of k-means training samples per partition, for every IVF/HNSW index type. Default `256`. Higher values increase both accuracy and training time. | + +#### Search-time Parameters + +| Parameter | Description | +| :--- | :--- | +| `limit` | Number of results to return (the `k` in `k-ANN`). | +| `nprobes` | Sets both `minimum_nprobes` and `maximum_nprobes` to the same value in Lance. Leave unset to use Lance's adaptive defaults. At very high scales you will likely need to experiment to find your preferred recall / latency balance. | +| `minimum_nprobes` | Minimum number of partitions scanned. Leave unset to use Lance's default. | +| `maximum_nprobes` | Maximum number of partitions scanned. Only scans more than `minimum_nprobes` if an initial pass does not return enough results, which is useful for narrow filters. Leave unset, or set to `0`, to remove the cap. | +| `ef` | HNSW search-time exploration factor. Start around `1.5 * k` and increase up to `10 * k` for higher recall. | +| `refine_factor` | Reads and reranks additional candidates in memory to recover recall lost to quantization. Start between `5` and `50` (a factor of `25` reads and reranks the top `25 * k` candidates) and measure the latency cost, typically a few milliseconds, against the recall gained. | +| `distance_range(lower_bound, upper_bound)` | Return only rows whose distance falls within `[lower_bound, upper_bound)`. Either bound is optional. Useful for near-duplicate detection or "close-enough" matching. | +| `bypass_vector_index()` | Ignore the ANN index entirely and perform an exact (flat) scan. Can be used to measure ANN `recall@k`, or to query with a metric the index was not built for (e.g., a non-cosine query on a multivector column). | + + +The `distance_type` can be specified at search time in addition to build time. If +you do this, set it to the same value used to build the vector index. If the search +metric does not match the index metric, LanceDB cannot use the index and falls +back to a costly flat search. On LanceDB Cloud, the brute-force KNN safety limit +can reject that search on a large table instead of executing it. An Enterprise +deployment applies the same limit only when it is configured to. + +When the search metric is omitted, current SDKs use the index metric if an index +is available. Some older SDK versions sent `l2` when it was omitted, so explicitly +set the matching metric or upgrade the SDK when querying a non-`l2` index with an +older client. + + +**Recommended `nprobes` behavior by index type:** + +| Index type | Guidance | +| :--- | :--- | +| `IVF_HNSW_FLAT`, `IVF_HNSW_SQ` | Leave the probe settings unset, then tune `ef` first. Expect higher latency variance under filtered search. | +| `IVF_RQ`, `IVF_PQ` | Leave the probe settings unset and configure them only when recall is insufficient. If using a selective filter you may need to increase `maximum_nprobes` if you do not receive enough results. | + + + +**Filtered queries and adaptive `nprobes`.** When a `where(...)` filter is active, LanceDB initially scans `minimum_nprobes` +partitions and uses a wider scan if too few rows are found. +Set `minimum_nprobes == maximum_nprobes` or call `nprobes(n)` to instead fix the partition count. +Whether a deployment widens the scan this way depends on its version; one that does not scans exactly +`minimum_nprobes` partitions. + + +Here is an example of a vector search exercising several of the above parameters. + + + + {VectorIndexNprobes} + + + + +LanceDB also supports advanced search-time controls for thresholded retrieval, recall measurement, and working around index-level metric constraints. + +**Thresholding with `distance_range`:** + + + + {VectorIndexDistanceRange} + + + +**Using `bypass_vector_index`:** + +Use `bypass_vector_index` to compute an exact **kNN** result. Note that exact queries may be prohibitively slow on production scales. + + + + {VectorIndexBypassRecall} + + + + +Multivector indexing currently requires `distance_type="cosine"`. Use `bypass_vector_index()` for non-`cosine` queries on a multivector column. See [Multivector Search](/search/vector-search) for the full rules. + + +#### Async API and Config Objects + +Create vector indexes asynchronously with `await table.create_index("vector", config=...)`. The `config` object +admits the same build-time parameters described above. Pass an instance of a Python config class from the table in [Choosing the Right Index](#choosing-the-right-index): + + + + {VectorIndexAsyncConfig} + + + +### IVF Indexes + +This example creates and queries an `IVF_PQ` index for a table of vectors with respect to `cosine` similarity. +Specify `vector_column_name` if you have multiple vector columns or non-default names. + + + + {VectorIndexBuildIvf + VectorIndexQueryIvf} + + + + +TypeScript currently doesn't support `IvfSq` (IVF with Scalar Quantization). + + +For a vector field nested inside a struct, pass its full dotted path as `vector_column_name` (e.g. `image.embedding`). The same path is used at query time and is what `list_indices()` reports under `columns`. See [Selecting the vector column](/search/vector-search#selecting-the-vector-column) for the full path syntax. + + + + {VectorIndexNestedField} + + + +### IVF-HNSW Indexes + +Beyond the general build-time parameters above, two additional parameters are specific to IVF-HNSW indexes: + +| Parameter | Description | +| :--- | :--- | +| `m` | The number of neighbors to select for each vector in the HNSW graph. | +| `ef_construction` | The number of candidates to evaluate during the construction of the HNSW graph. Start at `150`; increase for better recall, decrease for faster indexing. | + +Partition sizing follows the general `num_partitions`/`target_partition_size` guidance above. +The snippet below builds and queries an `IVF_HNSW_SQ` index. + + + + {VectorIndexBuildHnsw + VectorIndexQueryHnsw} + + + +### Managing Vector Indexes + + Enterprise-only +In LanceDB Enterprise, vector indexes are managed **automatically**. The system asynchronously updates and optimizes indexes as a background process: +- Automatically manages indexing parameters and storage +- Can build an `IVF_PQ` index automatically on a vector column the deployment is configured to index +- GPU-based `IVF_PQ` builds are available on request. [Contact support](/deployment/support) to enable them for your deployment. Build time depends on dataset size, dimensions and GPU resources. + + Open-Source + LanceDB OSS users can manually create vector indexes by calling `table.create_index()`. + See the above sections for guidance on manually tuning index parameters as data changes. + + +In LanceDB Enterprise, `create_index()` returns immediately and the vector index builds asynchronously. +To wait until all data is indexed, specify the `wait_timeout` parameter, or call `wait_for_index(...)` afterward. +It waits for the named index to exist and for `index_stats(...)` to report `num_unindexed_rows == 0`. +In the embedded library the index is built before `create_index()` returns. + + + +Rows appended after an initial index build remain outside the index until refreshed manually (OSS) or automatically (Enterprise). Normal +search still checks those unindexed rows with a slower fallback path; `fast_search()` skips that +fallback and searches only indexed rows. + + + +**Operational checks** + +In the embedded library, use `optimize()` after appends or other writes to fold new rows into existing indexes. +A deployment does this in the background, and `optimize()` is not available there. + +#### Check Index Status + +In LanceDB Enterprise, vector index creation runs in the background and may take some time to complete. +While it is ongoing, you can check its status through the API or the **LanceDB Enterprise UI**. + +In the LanceDB Enterprise UI, navigate to your table page - the "Index" column reflects each column's index status: it is blank when no index exists, shows an "in progress" label while the index is being built, and shows the index type once the build completes. + +To check status programmatically, use `list_indices()` and `index_stats()`. **By default**, the index name is formed by appending `_idx` to the column name (e.g., a `keywords_embeddings` column produces `keywords_embeddings_idx`). Note that `list_indices()` only returns information after the index is fully built. + +Each entry returned by `list_indices()` also carries detailed per-index metadata, so you can inspect an index without a follow-up `index_stats()` call. Node.js exposes the same fields in camelCase (`num_indexed_rows` → `numIndexedRows`): + +| Parameter | Description | +| :--- | :--- | +| `num_indexed_rows`, `num_unindexed_rows` | Index coverage over the table | +| `size_bytes` | Total size of the index files on disk | +| `num_segments`, `index_version` | On-disk layout and format version | +| `created_at` | Creation time (ms since the Unix epoch in Node.js) | +| `index_uuid`, `type_url` | Internal identifiers for the index segment | +| `index_details` | Type-specific details (e.g. IVF partition counts or quantization settings) | + + + + + {VectorIndexCheckStatus} + + + + + +These fields are populated for local tables. In LanceDB Enterprise, `list_indices()` returns them except `num_unindexed_rows`; use `index_stats()` for index coverage. + +#### Custom Index Names + +The `{column}_idx` suffix is the default naming convention. +Pass `name=...` to `create_index()` to override it. Once set, the custom name will be reflected in `list_indices()`, `index_stats(name)`, and `wait_for_index([name])`. + + + + {VectorIndexCustomName} + + + +## Quantization {#quantization} + +**Quantization** is used in LanceDB to efficiently compress and store vector indexes. We discuss only the quantization techniques here; +discussion of LanceDB vector indexes and quantized vector indexes can be found [here](/indexing/vector-index). + +### Quantization Techniques +LanceDB provides $3$ distinct quantization techniques: Product Quantization (PQ), RaBitQ Quantization (RQ), and Scalar Quantization (SQ). +Recall that all quantizations perform **lossy** compression, in that they irreversibly lose some degree of precision to +compactly store an index. + +#### Product Quantization (PQ) +To visualize PQ, assume a vector dataset has $d$ dimensions, with a **chunk** of a vector denoting a contiguous block of entries. Imagine that each vector has + $m$ disjoint chunks of $d/m$ entries each, where the first chunk contains entries $0$ through $d/m-1$, the second contains +entries $d/m$ through $2d/m-1$, and so on. + +Now, for each $i$, let $S_i$ represent the set containing chunk $i$ of each vector (entries $(i-1)d/m$ to $id/m-1$). +For each $S_i$ independently, a small set of **centroids** is computed corresponding to an approximate solution to the $k$-means clustering problem. + +For each original vector in the dataset, every chunk is associated to its nearest centroid; thus, the vector itself is associated with the concatenation of $m$ centroids. +We then gather all our centroids (from all chunks) into a single lookup table, and for each vector, we store the concatenation of IDs of its corresponding centroids. +At query time, we need only to compare each chunk of the queried vector with our set of centroids. + + + IVF vector-space partitioning + + +In the above example, the original vector is split into chunks (subvectors), each of which is associated to a centroid. The stored quantization code for this vector +is the concatenation $2 || 1 || 4 || 3$. The original vector required $128$ dimensions $\times 32$-bit floats $ =4096$ bits total, +which has been compressed to $4$ chunks $\times 8$-bit integers $= 32$ bits of quantized storage. + +#### RaBitQ Quantization (RQ) + +RaBitQ is an advanced quantization technique that outperforms PQ in several ways. +It needs no codebook to train, estimates distances very quickly at query-time, +and crucially, quantizes each vector in (with some small overhead) just **one bit per dimension!** +In practice, RaBitQ compresses a $1024$-dimensional `float32` vector into just a few thousand bits, while maintaining good recall. + +The inner workings of RaBitQ quantization are rather mathematically dense. It generates a quantization codebook by +applying a uniformly random, approximately distance-preserving orthogonal transformation of the vertices of the $d$-dimensional hypercube, +where $d$ is the dimensionality of the dataset. We defer the details, and an elegant theoretical error bound, to [the original paper.](https://arxiv.org/pdf/2405.12497) + +##### Using RaBitQ +Use RaBitQ quantization by selecting quantized index types ending in the suffix `RQ`. For example, call `create_index` with `index_type="IVF_RQ"`. +Note that when using `IVF_RQ`, the dimension of the dataset must be a multiple of `8`. + +`num_bits` determines how many bits are used to quantize each dimension. +`1` is the standard RaBitQ setting. Increase to `2`, `4`, or `8` bits to achieve better recall for additional storage and query-time compute. + + +RaBitQ-quantized indexes computed with `num_bits >= 2` use a newer on-disk layout, and cannot be read by some older LanceDB versions. + + +See this [blog post](https://lancedb.com/blog/feature-rabitq-quantization/) for further discussion and benchmarking of LanceDB's RaBitQ implementation. + +#### Scalar Quantization (SQ) +Scalar quantization quantizes each entry of a vector independently, by simply replacing it with the closest of a pre-defined set of values. +In practice, it often uses $8$ bits per dimension of a vector, and supports very fast encoding and decoding. + +For example, suppose we know all vector entries across our dataset lie in the range $[-128 \times 10^5, 127 \times 10^5]$. +In this case, we could quantize a given value $v$ as an $8$-bit representation of the integer $j$, where $j \times 10^5$ is the closest value to $v$ +among all integral multiples $\{j \times 10^5: -128 \leq j \leq 127 \}$. + +### Quantization API Reference + + +| Parameter | Description | +| :--- | :--- | +| `num_bits` | Bits per dimension for quantization. Only applies to `IVF_PQ`/`IVF_HNSW_PQ` (default `8`) and `IVF_RQ` (default `1`, RaBitQ); not used by `IVF_FLAT`/`IVF_SQ`/`IVF_HNSW_FLAT`/`IVF_HNSW_SQ`. Higher values improve accuracy at the cost of additional storage. | + +`max_iterations` and `sample_rate` also affect quantizer training, but since they apply to every IVF/HNSW index type (not just quantized ones), they're documented as general [Build-time Parameters](/indexing/vector-index#build-time-parameters) instead.

Any data supplied to the create call is ignored +when the table already exists. + +Inspect the returned table's schema if your code depends on specific columns +or types.

Choose this only when +you intend to replace its previous contents. + +The following Python program demonstrates both choices: + + + {CreateTableConflictHandling} + + + + + + +`exist_ok` / `existOk` does not append the provided data to an existing table. Use +[`table.add()`](/ingestion/insert) for that. If you need to ensure a table exists *and* +contains specific rows, choose an explicit [merge policy](/ingestion/merge-insert). Creating an empty table +and repeatedly appending the same batch does not deduplicate it. + + +### From a custom schema {#from-a-custom-schema} + +You can define a custom Arrow schema for the table.

If later writes omit a +non-nullable column, or provide actual nulls for it, ingestion fails; nullable columns can be +omitted or written with null values. Without an explicit schema, Python infers list-like vector +values as fixed-size `float32` vector fields from the observed dimension. + +For Python ingest, malformed vector values fail by default. If you expect occasional wrong-length, +null, or NaN vectors, choose an `on_bad_vectors` policy: `"drop"` removes those rows, `"fill"` writes +`fill_value`, and `"null"` writes nulls. + +### From an Arrow Table {#from-an-arrow-table} +You can also create LanceDB tables directly from Arrow tables. +Rust uses an Arrow `RecordBatchReader` for the same Arrow-native ingest flow. + + + + {CreateTableFromArrow} + + + + {TsCreateTableFromArrow} + + + + {RsCreateTableFromArrow} + + + + +### From a Pandas DataFrame {#from-a-pandas-dataframe} +Python Only + + + + {CreateTableFromPandas} + + + + +Data is converted to Arrow before being written to disk.

Install `polars` for this example; the +conversion preserves the table structure through Arrow. + + + + {CreateTableFromPolars} + + + +### From Pydantic Models {#from-pydantic-models} +Python Only + +When you create an empty table without data, you must specify the table schema. +LanceDB supports creating tables by specifying a PyArrow schema or a specialized +Pydantic model called `LanceModel`. + +For example, the following Content model specifies a table with 5 columns: +`movie_id`, `vector`, `genres`, `title`, and `imdb_id`. When you create a table, you can +pass the class as the value of the `schema` parameter to `create_table`. +The `vector` column is a `Vector` type, which is a specialized Pydantic type that +can be configured with the vector dimensions. It is also important to note that +LanceDB only understands subclasses of `lancedb.pydantic.LanceModel` +(which itself derives from `pydantic.BaseModel`). + + + + {CreateTableFromPydantic} + + + +#### Nested schemas {#nested-schemas} + +Sometimes your data model may contain nested objects. For example, you may want to store the document string and the document source name as a nested Document object: + + + + {TablesDocumentModel} + + + +This can be used as the type of a LanceDB table column: + + + + {CreateTableNestedSchema} + + + +This creates a struct column called "document" that has two subfields +called "content" and "source": + +```bash +In [28]: tbl.schema +Out[28]: +id: string not null +vector: fixed_size_list[1536] not null + child 0, item: float +document: struct not null + child 0, content: string not null + child 1, source: string not null +``` + +#### Validators {#validators} + +Because `LanceModel` inherits from Pydantic's `BaseModel`, you can combine them with Pydantic's +[field validators](https://docs.pydantic.dev/latest/concepts/validators). The example +below shows how to add a validator to ensure that only valid timezone-aware datetime objects are used +for a `created_at` field. + + + + {TablesTzValidator} + + + +The example catches a `ValidationError` for the timestamp with a different +timezone. A validator runs when the Pydantic model is constructed; declaring a +model as the table schema does not make every later write run that validator. + + +Datasets too large to pass to `create_table` at once are covered separately; +see [Insert data](/ingestion/insert#large-datasets) for batches, file-backed +input and write parallelism. + + +## Create empty table {#create-empty-table} +You can create an empty table for scenarios where you want to add data to the table later. +An example would be when you want to collect data from a stream/external file and then add it to a table in +batches. + +An empty table can be initialized via an Arrow schema. + + + + {CreateEmptyTable} + + + + {TsCreateEmptyTable} + + + + {RsCreateEmptyTable} + + + +Alternatively, define the schema with `LanceModel`, a Pydantic model class +provided by `lancedb.pydantic`. Its `Vector` type declares a fixed vector dimension. + + + + {CreateEmptyTablePydantic} + + + +Once the empty table has been created, you can append to it or modify its contents, +as explained in [Ingesting data](/ingestion). + +## Open an existing table {#open-an-existing-table} + +You can open an existing table by specifying the name of the table to the `open_table` / `openTable` method. +If you forget the name of your table, you can always get a listing of all table names. + + + + {OpenExistingTable} + + + + {TsOpenExistingTable} + + + + {RsOpenExistingTable} + + + +## Drop a table {#drop-a-table} + +Use the `drop_table()` method on the database to remove a table. + + + + {DropTable} + + + + {TsDropTable} + + + + {RsDropTable} + + + +Dropping a table removes the table object. Deleting rows keeps the table and +changes its contents; retained versions and cleanup are described in +[Cleanup](/maintenance/cleanup). +On a local database, dropping a table that does not exist raises an error; in +Python, pass `ignore_missing=True` to suppress it. A deployment may report +success instead, depending on how it stores its catalog, so do not rely on the +error to tell you a table was missing.

A partitioned write goes up as a multipart write: the client cuts each partition into one or more `insert` parts and uploads them under a single upload id. Each part is streamed. Its size and duration still affect resource use and +timeouts: it has to finish within the client read timeout while the server writes it to object storage, so on very large ingests an oversized part can run past that timeout and surface as: + +```text +lancedb.remote.errors.HttpError: operation timed out +``` + +Two environment variables control how a multipart write's parts are cut. Both are picked up automatically by the Python and TypeScript clients, for clients that support these settings: + +| Variable | Default | What it controls | +|----------|---------|------------------| +| `LANCE_CLIENT_MAX_BYTES_PER_REQUEST` | 8 GiB | Maximum size of a single insert part, in LZ4-compressed Arrow IPC bytes. Set to `0` to disable splitting and send one request per partition. | +| `LANCE_CLIENT_MAX_REQUEST_DURATION` | Half the read timeout | Maximum wall-clock time, in whole seconds, that any one insert part may stay open. Set to `0` to disable the time-based cut. | + +A part is cut after the input batch that reaches either limit, so cuts fall between batches. Lower the byte budget, with smaller input batches, when large ingests hit the read timeout; lower the duration when uploads are slow or throttled and the byte budget isn't the limiting factor. + +```bash +export LANCE_CLIENT_MAX_BYTES_PER_REQUEST=1073741824 # 1 GiB +export LANCE_CLIENT_MAX_REQUEST_DURATION=120 # 2 minutes +``` + +Splitting into more parts does not change the final table. The server stages the parts under their shared upload ID before committing +the write.

Returns matching facts with scores and provenance. | +| `lancedb_remember` | Stores a durable fact when you explicitly ask. Deduplicated by content hash, so remembering the same thing twice doesn't pile up rows. | +| `lancedb_read` | Fetches a single memory by ID, optionally with the original conversation messages it was distilled from. | +| `lancedb_forget` | Deletes safely: previews candidates first, then deletes by exact ID, so nothing disappears by accident. | + +Beyond these tools, the plugin also captures durable facts from your conversations +automatically: an auxiliary model distills them before context is compressed and again when a +session ends, so insights survive even when the raw messages are summarized away. + +## Walkthrough {#walkthrough} + +"_Teach it your project preferences_" + +Let's make this concrete with the pain we opened on: re-explaining your setup to the agent every session. +We'll save a convention once and then prove a brand-new session can recall it. This example will touch all four +tools along the way. + +### Remember {#remember} + +Ask Hermes to commit a convention to long-term memory. Saying "remember in long-term memory" +makes sure it lands in the LanceDB store, which shows up as the `⚡ lancedb_r` (`lancedb_remember`) +line below: + +```text +● Remember in long-term memory: for this project I only use uv, never pip, and I always add type hints to Python functions. + + ┊ 🧠 memory +memory: "For this project, the user only uses uv for Python package management, never pip, and always adds type hints to Python functions." + ┊ ⚡ lancedb_r 0.0s + ─ ⚕ Hermes ──────────────────────────────────────────────────────────────── + + Remembered. I've stored that project convention: use uv only, never pip, and always add type hints to Python functions. +``` + +### Recall {#recall} + +First, take Hermes' built-in notes out of the picture so recall can *only* come from LanceDB +(the two layers run side by side otherwise, and either could answer): + +```bash +hermes config set memory.memory_enabled false +``` + +Now start a fresh session (`/new`) and ask for the convention back, worded completely +differently from how you saved it: + +```text +● /new +● Look through your long-term memory for my Python project preferences. + + ─ ⚕ Hermes ──────────────────────────────────────────────────────────────── + + I found one durable memory about Python project preferences: + + - Project Python tooling preference is uv; pip is not used; type hints are required. +``` + +This is the whole point in one exchange. You asked about your *preferences* using none of the +words you stored the fact with (no *uv*, no *pip*, no *type hints*), yet a fresh session, with +none of the earlier conversation in context, pulls it straight back. Semantic search matches on +meaning rather than exact wording, which is precisely where keyword search falls short. + + +Turn the built-in layer back on for everyday use with `hermes config set memory.memory_enabled true`. +The two memory layers happily coexist. We only disabled it here to prove the recall came from +LanceDB. + + +### Read {#read} + +You can also ask where a fact came from. Hermes attributes the answer to its stored memory +rather than guessing from a file in the repo (under the hood, `lancedb_read` can also return +the exact source messages a fact was distilled from): + +```text +● Where did that uv preference come from? + + ─ ⚕ Hermes ──────────────────────────────────────────────────────────────── + + It came from the project's persistent memory, not from a codebase file I inspected. + + Specifically, the recalled memory says: + - "For this project, the user only uses uv for Python package management, never pip, and always adds type hints to Python functions." +``` + +### Forget {#forget} + +When a preference changes, ask Hermes to drop the old fact. The tool calls tell the whole +story: the two `⚡ lancedb_f` (`lancedb_forget`) lines are it previewing matches and then +deleting, and the trailing `⚡ lancedb_r` is it saving the replacement in the same breath: + +```text +● I've switched from uv to pixi. Forget the uv preference. + + ┊ ⚡ lancedb_f uv preference python package management never pip type hints 0.3s + ┊ ⚡ lancedb_f 0.0s + ┊ ⚡ lancedb_r 0.2s + ─ ⚕ Hermes ──────────────────────────────────────────────────────────────── + + Done — I removed the uv preference from memory and replaced it with: + + - This project uses pixi for Python package management + - Type hints on Python functions are still preferred +``` + +Remember, recall, read, forget: four small operations that between them cover the entire +lifecycle of a durable memory. + +## Retrieval modes {#retrieval-modes} + +Recall ships in `vector` mode by default: pure semantic search, which is what survives the +paraphrasing you saw above. If you also need exact name or jargon matching, switch to `hybrid` +(vector + BM25) and choose how the two legs are fused: RRF, a vector-biased linear blend, or a +cross-encoder reranker. Mode is set per call; fusion is a config setting. + +```yaml +# ~/.hermes/config.yaml +plugins: + lancedb: + retrieval: + mode: hybrid # vector (default) | hybrid + reranker: + type: rrf # how the vector + BM25 legs are fused + # Swap RRF for a reranking pass (pulls in sentence-transformers + torch): + # type: cross-encoder + # model: cross-encoder/ettin-reranker-17m-v1 + # rerank_top_n: 50 +``` + +The cross-encoder is the one path that pulls in a local ML stack, so it stays opt-in. It +defaults to the compact 17M-parameter [ettin reranker](https://huggingface.co/cross-encoder/ettin-reranker-17m-v1). + +## Inspect the store {#inspect-the-store} + +Everything lives in one table named `memories` at `~/.hermes/lancedb/memories.lance`. Because +it's a plain LanceDB table, you can open it directly and see exactly what the agent has stored. +A `kind` column separates extracted `fact` rows from the raw `turn` rows they were drawn +from: + +```python +import lancedb + +db = lancedb.connect("~/.hermes/lancedb") +tbl = db.open_table("memories") +print(tbl.to_pandas()[["kind", "category", "content"]].head()) +``` + +## Configuration {#configuration} + +The plugin runs on sensible defaults once activated: you don't have to configure anything. +`~/.hermes/config.yaml` is purely for overrides. Two common ones: + +Use a cheaper model for the auxiliary fact-extraction calls: + +```yaml +# ~/.hermes/config.yaml +auxiliary: + lancedb_extraction: + provider: openrouter + model: google/gemini-3-flash +``` + +Point embeddings at a fully local endpoint (for example, Ollama) so nothing leaves your +machine: + +```yaml +# ~/.hermes/config.yaml +plugins: + lancedb: + embedding: + model: nomic-embed-text + base_url: http://localhost:11434/v1 + api_key_env: OLLAMA_API_KEY # any value works for local Ollama +``` + + +Changing the embedding model (or its dimension) against an existing store requires recreating +the table. The plugin fails loudly on a dimension mismatch rather than silently returning +nothing. Every option is documented in the plugin's [`default_config.yaml`](https://github.com/lancedb/hermes-agent-memory/blob/main/src/default_config.yaml). + + +## Benchmark {#benchmark} + +On [LongMemEval-S](https://huggingface.co/datasets/xiaowu0162/longmemeval-cleaned), a +long-conversation QA benchmark, LanceDB's semantic recall clearly beat Hermes' built-in lexical +search (0.66 vs. 0.53 answer accuracy) by finding the right messages even when the question was +worded differently from the original conversation.

Note that there's an image embedding column that's +a fixed-size list of 768-dimensional floats, and a binary column containing the raw JPEG bytes of the image. +``` +image_path: string +caption: string +NSFW: string +similarity: double +LICENSE: string +url: string +key: string +status: string +error_message: null +width: int64 +height: int64 +original_width: int64 +original_height: int64 +exif: string +md5: string +img_emb: fixed_size_list[768] + child 0, item: float +image: binary +``` + +When inspecting Lance datasets from Hugging Face, it's also a good idea to check whether the dataset author included +any pre-built indexes that you can use for search. You can check the available indexes with: + +```python +print(table.list_indices()) +``` +``` +[ + Index(IvfPq, columns=["img_emb"], name="img_emb_idx"), + Index(FTS, columns=["caption"], name="caption_idx") +] +``` + +In this case, we see that we have an IVF_PQ vector index on the `img_emb` column, and an FTS index on the `caption` +column, which means we can directly do vector search on the image embeddings and keyword search on the captions +without needing to build the indexes ourselves! + + +If you see an empty list, it may be because the dataset author did not include the index files when uploading +to Hugging Face. You can download the dataset locally, and build the indexes yourself. See the [indexing guide](/indexing/) +for instructions on building different types of indexes with LanceDB. + + +## Projection scan {#projection-scan} + +Run a simple scan by projecting relevant columns to get a feel for the dataset. For example, we +can run a search without any filters or input parameters to get a small subset of the data: + +```python +rows = ( + table.search() + .select(["caption", "url", "similarity"]) + .limit(3) + .to_list() +) + +for i, row in enumerate(rows, start=1): + print(f"{i}. {row['caption']}") + print(f" url={row['url']}") + print(f" similarity={row['similarity']}") +``` + +We get the first three rows and their metadata printed out, which look like this: +``` +1.

Upload your local directory to the Hub {#1-upload-your-local-directory-to-the-hub} + +Upload the full local directory to a specified repository on the Hugging Face Hub. The command below uploads the contents of your local LanceDB directory at `/path/to/your_local_dir` to a new repository named `your_hf_org/repo_name` under your Hugging Face account. + +```bash bash icon="code" +hf upload-large-folder /path/to/your_local_dir your_hf_org/repo_name \ + --repo-type dataset \ + --revision main +``` + + +The `upload-large-folder` command is designed for [uploading large datasets](https://huggingface.co/docs/huggingface_hub/en/guides/upload) (potentially terabytes in size) and will handle multipart uploads, retries, and resuming interrupted uploads. + + +### 2\. Inspect dataset versions {#2-inspect-dataset-versions} + +Because you can query your remote dataset directly from Hugging Face with `hf://` URIs in LanceDB, you can easily inspect the dataset versions and updates on the Hub without needing to download the data locally. This is very useful to keep track of changes to the dataset and iterate on your data collection and curation process. + +```python Python icon="python" +import lancedb + +db = lancedb.connect("hf://datasets/your_hf_org/repo_name") +table = db.open_table("table_name") + +versions = table.list_versions() +print(versions) +``` +This will print out the list of versions available for the dataset on the Hub, along with their metadata such as creation date and description. + +### 3\. Add a dataset card {#3-add-a-dataset-card} + +The Hub dataset card allows you to communicate the schema and usage of the dataset to other developers. It sits at the repo's root in a file named `README.md` on the Hub. +This project keeps the source card text in `HF_DATASET_CARD.md`, so you can publish updates +to the dataset there and upload it as `README.md` using the following command on the HF CLI: +this requires a regular `hf upload` because it is a single-file upload to a specific target path (a custom commit message can be added if you wish). + +```bash +hf upload lancedb/magical_kingdom HF_DATASET_CARD.md README.md \ + --repo-type dataset \ + --commit-message "Update dataset card" +``` + +### 4\. Update the dataset {#4-update-the-dataset} + +Over time, you may want to add new rows (append) or columns (backfill) to your dataset as your needs evolve. You can make the necessary updates to your local dataset using LanceDB, and then upload the updated version back to the Hub with the same `hf upload-large-folder` command. + +```bash bash icon="code" +hf upload-large-folder /path/to/your_local_dir your_hf_org/repo_name \ + --repo-type dataset \ + --revision main +``` +The CLI will only upload the new data that has changed since the last upload, avoiding wasted I/O while making it easy to keep your dataset up-to-date on the Hub. + +That's it! Your dataset is now updated on the Hub with the new data and schema changes, and other users can query the latest version of the dataset directly from Hugging Face with `hf://` URIs in LanceDB. + +## Explore more Lance datasets on Hugging Face {#explore-more-lance-datasets-on-hugging-face} + +The LanceDB team is actively uploading useful and interesting datasets in Lance format to the Hugging Face Hub +under the [lance-format](https://huggingface.co/lance-format) organization.

If you +already use [Geneva](/geneva), it remains available; see +[Geneva and Functions](/geneva#functions) for how its concepts map onto these. + +The steps below take a column of numbers to a filled column of their doubles. + +## Define a function {#define} + +`@udf` packages a scalar Python callable.

A scalar +output must be non-nullable, because a physical NULL is what marks a +computed-column row as unfilled. A named-struct output may declare nullable +fields: whether a row has a result at all is the struct's own validity, which +Enterprise keeps in a separate internal column when it expands the result into +sibling columns, so a null field is a value rather than a missing row. + +## Connect and create a table {#table} + +The remaining steps run against your Enterprise deployment. Replace the database +URI, API key, region and endpoint below with your deployment details. In application +code, load credentials from environment variables or a secrets manager: + + +{FunctionConnect} + + +For an ordinary stored input column, the Arrow type must match the parameter. +A nullable column requires a nullable parameter, such as `Optional[float]`; +a non-nullable column can bind to either. This example uses `value: float`, +so the table declares `value` non-nullable. + +Computed-column inputs depend on the Enterprise server version. Where supported, +they bind to non-nullable parameters even though the physical column is +nullable: refresh skips rows whose computed input is still null. Check your +deployment's support before using another computed column as an input. + + +{FunctionCreateTable} + + +## Register it {#register} + +Registration returns a job; the immutable version exists once the job succeeds. + + +{FunctionRegister} + + +`create_function` is the blocking equivalent. A registered version is fetched +with `db.get_function(name, version=...)`. + + +**Enterprise job type:** `create_function`. Registration returns a job because +the function is baked into an image before the version becomes usable. + + +## Apply it as a column {#apply} + +Calling the registered version binds each parameter, by name, to a column with +`col(...)`. `add_columns` declares the result as a new column: + + +{FunctionApply} + + +The column is declared empty; the function has not run yet. A mapping with one +function application keeps its scalar or named-struct result in the named +column. A bare named-struct application expands its result fields as one atomic +binding, with aliases from `rename(columns=...)`. + +## Fill the column {#refresh} + +A refresh runs the function on the cluster as a [job](/basics/jobs). `wait()` +blocks until the job finishes and returns its result, including how many rows +it filled: + + +{FunctionRefresh} + + +The filled values are read like any other column: + + +{FunctionInspect} + + +Filling then works as it does for a SQL computed column: a later refresh fills +rows added since the last one and recomputes rows whose inputs changed, and +leaves filled rows with unchanged inputs alone. See +[Refresh a column](/feature-engineering/refresh-column). + +## Read and produce blobs {#blobs} + +A Function can bind a [Blob v2 column](/management/table#managed-blobs) and +return another blob. In row mode, a top-level blob parameter arrives as Python +`bytes`, or `None` for a nullable input. The worker reads the payload before +calling your function. Return bytes and let the destination table store the +Managed payload and descriptor. + +Declare blob inputs and outputs explicitly. This example reverses the bytes +to demonstrate the round trip without requiring an image library. Here `db` +is an Enterprise database and `table` contains an `image` Blob v2 column +with table schema metadata `lance.blob.managed=true`, as in the +[table creation example](/management/table#managed-blobs-read-write): + +```python +from datetime import timedelta + +import lancedb +from lancedb import col +from lancedb.functions import udf +import pyarrow as pa + +@udf( + name="reverse_image", + python_version="3.12", + pip=["pyarrow==26.0.0"], + input_schema=pa.schema([lancedb.blob("image")]), + output_schema=lancedb.blob("reversed", nullable=False), +) +def reverse_image(image): + return b"missing" if image is None else image[::-1] + +function = db.create_function_async(reverse_image).wait( + timeout=timedelta(minutes=15) +) +table.add_columns({"reversed": function(image=col("image"))}) +result = table.refresh_column_async("reversed").wait( + timeout=timedelta(minutes=15) +) +assert result.rows_failed == 0 + +hits = table.search().select(["id", "reversed"]).with_row_id(True).to_arrow() +values = table.fetch_blobs("reversed", hits).to_pylist() +``` + +An empty byte string is a filled result. A scalar output cannot be nullable, +because a physical NULL marks an unfilled computed row. To return a nullable +blob as a value, use a named-struct output schema with a nullable blob field; +the struct itself records whether the result has been filled. Read a nested +blob with `table.fetch_blobs("payload.image", hits)`. + +On deployments that support computed-column inputs, another Function can bind +to `col("reversed")`. Refresh the producer first, then the consumer. Once +outputs are current, a later refresh fills appended rows. A filtered refresh +preserves payload references for unselected Managed outputs. An unfiltered +refresh can recompute a whole fragment when it cannot establish that the +fragment's outputs are current. + +Function output blobs follow the same compaction and cleanup lifecycle as +ingested Managed blobs.

Changing a dependency +produces a new version rather than altering the one already registered, so a +column filled by version 1 is unaffected by version 2. + +Declaring them is not optional bookkeeping. If the worker environment differs +from the one the function was written against, the failures are among the +hardest to diagnose in the system, because the error rarely names the cause. + +### Symptoms of an environment mismatch {#mismatch-symptoms} + +| Symptom | Likely cause | +| --- | --- | +| `TypeError: Enum.__new__() missing 1 required positional argument` | `attrs` version mismatch | +| `TypeError: Can't instantiate abstract class` | package structure differs between versions | +| `ArrowInvalid: cannot cast`, or serialization errors | NumPy 1.x against 2.x | +| `ModuleNotFoundError` on the worker | package installed locally but not declared | +| Model loading failures | PyTorch version mismatch | +| Permission denied | an API key present locally but absent from `env` | + +The packages worth pinning explicitly, because a mismatch in them produces the +errors above rather than a clear one: **numpy, torch, pyarrow, attrs, +pydantic**. + + +The client version defaults `python_version`, so a function registered from a +3.11 environment runs on 3.11 unless you say otherwise. That default is usually +right and occasionally surprising. Pin it when the function is sensitive to it. + + +## Failure handling {#failures} + +A function that raises fails the job. There is no per-row retry or skip policy +in the function definition: `@udf` takes no error-handling parameter, so a +function that calls a flaky external service should handle that itself, inside +the function body. + +Letting the job fail is the other option: fix the cause and refresh again. The +next refresh [skips rows that are filled and current](/feature-engineering/refresh-column#idempotent), +but how much of the failed job's work was kept is not guaranteed, so do not +count on the retry costing only the rows that did not complete. + +## What gets packaged {#packaging} + + +The artifact is a **snapshot**: the function source, plus exactly the +module-level names it references (modules as imports, importable classes and +functions as imports, literals inlined). + +Code that reaches the module namespace another way is rejected where it can be +seen and unsupported where it cannot: `globals()`, `eval`, `sys.modules`, +`builtins`. Closures and a non-standard `__builtins__` are rejected outright. + + +In practice this means a function should be self-contained: take its inputs as +arguments, import what it needs at module level, and avoid capturing state from +the surrounding scope. + +## Drop it {#drop} + +`db.drop_function(name, version=...)` drops the function's name and the object +it is bound to; `version` must be a version that exists. It returns `False` if +the name was already gone. Deleting the object's content can finish after the +call returns, as a [background job](/maintenance/background-jobs). +`drop_function_async` returns that job with the result, so you can wait for it. + +A deployment refuses the drop unless it also allows changes to a function's +lifecycle, which is a separate setting, off by default even where Functions are +enabled. + +## What to read next {#next} + + + + Refresh semantics, and the SQL alternative. + + + Built-in embedding providers, which need no registration. + + diff --git a/docs/web/management/index.mdx b/docs/web/management/index.mdx new file mode 100644 index 000000000..21222f418 --- /dev/null +++ b/docs/web/management/index.mdx @@ -0,0 +1,160 @@ +--- +title: "Management" +sidebarTitle: "Overview" +description: "Create, list, and drop the objects in a catalog, from Python, TypeScript, or SQL." +icon: folder-tree +keywords: ["ddl", "create", "drop", "list", "catalog", "management"] +--- + +Use the SDKs or SQL to manage [catalog objects](/basics/catalog), including +tables, namespaces and views.

[Naming rules](/basics/naming) has the lengths and the other limits. + +## Directory namespaces {#directory-namespaces} + +The simplest namespace model in LanceDB is a single root namespace, often represented by one +directory. Namespaces can nest inside it, as in this hierarchy: + +```bash +./local_lancedb (root) +└── prod + └── search + └── user (table) + └── data (table) +``` + +The hierarchy is logical, not a tree of folders: a directory namespace records it in a +`__manifest` table in the root directory, and stores each table in a directory of its own there. + +As a user of LanceDB OSS, you might never notice namespaces at first, because a plain connection +uses only the root namespace, which is implicit.

For loading records, see [Ingestion](/ingestion). For changes to +columns, see [Schema evolution](/management/table#schema). + + +In LanceDB Enterprise, tables are also created and dropped in SQL with [`CREATE TABLE` and `DROP TABLE`](/sql/ddl/table). + + +## Table structure and metadata {#carries} + +| | | +| --- | --- | +| **Columns** | including vectors, blobs, and [computed](/feature-engineering/add-computed-column) columns | +| **Versions** | every write commits one, so reads can [travel back](/management/table#versioning) | +| **Indexes** | vector, full-text and scalar, built over its columns | +| **Branches** | isolated lines of change you can [merge or discard](/tables/branching) | + +## Create a table {#create} + + +```python Python icon="python" +tbl = db.create_table("documents", data) +tbl = db.create_table("documents", schema=schema) # empty, typed +``` + +```typescript TypeScript icon="square-js" +const tbl = await db.createTable("documents", data); +const tbl = await db.createEmptyTable("documents", schema); +``` + +```sql SQL +CREATE TABLE documents (id BIGINT, title VARCHAR) +``` + + +`data` can be a list of objects, an Arrow table or reader, a pandas or polars +frame, or Pydantic models. [Ingesting data](/ingestion) covers each, plus +`exist_ok` and `mode="overwrite"` for re-runnable scripts. + + +An explicit schema is where nullability is decided. In the embedded library, +creation is also the only point at which a table can be given **stable row +ids**; in LanceDB Enterprise, whether a new table gets them is the deployment's +setting. See [Limits](/basics/limits#schema). + + +## Open and list tables {#open} + + +```python Python icon="python" +tbl = db.open_table("documents") +db.table_names() +``` + +```typescript TypeScript icon="square-js" +const tbl = await db.openTable("documents"); +await db.tableNames(); +``` + + + +Each accepts `namespace_path` to act inside a [namespace](/management/namespace) +rather than at the database root. + +To find out whether a table exists, open it and handle the error, or look for +its name in a listing. A missing table raises `ValueError` on a local directory +or a deployment, and `lance_namespace.TableNotFoundError` on a connection from +`connect_namespace`. A listing returns one page of names at a time, so check +every page. Python's `table_exists` is no substitute: a local directory or a +deployment raises `NotImplementedError` for it, and on a connection from +`connect_namespace("dir", ...)` or `connect_namespace("rest", ...)` it fails with +an `AttributeError`. TypeScript has no `tableExists`. + +## Rename and clone tables {#rename-clone} + +```python +db.rename_table("documents", "docs") + +db.clone_table( + "docs_snapshot", + source_uri="s3://bucket/db/documents.lance", + source_version=42, # or source_tag="release-1" + is_shallow=True, +) +``` + +Renaming is not supported on a local directory connection. In LanceDB Enterprise, +whether a table can be renamed or cloned at all depends on how the deployment +stores its catalog. + +A **shallow** clone (the default) references the source's data files rather +than copying them, so it is fast and cheap regardless of table size. It is the +practical way to branch an experiment off a known version, or to pin a training +set to the exact version a model saw. + + +A shallow clone depends on the source's files continuing to exist. If the source +is [compacted](/maintenance/compaction) past the retention window, the version +the clone points at can be pruned. Local OSS connections support shallow clones +only; `is_shallow=False` is not implemented. If the copy must outlive the +source's history, copy its data into an independent table instead. A deployment +that supports cloning also makes shallow clones only, and one whose catalog +does not support it refuses every clone. + + + +**Enterprise job type:** on an Enterprise cluster that drops tables in the background, +the teardown runs as a job: `drop_table`, which fences the table's directory +with a marker and deletes its content, or `drop_object`, depending on how the +deployment stores its catalog. See +[Background jobs](/maintenance/background-jobs#teardown). + + +## Drop a table {#drop} + + +```python Python icon="python" +db.drop_table("documents") +job = db.drop_table_async("documents") +db.drop_all_tables() +``` + +```typescript TypeScript icon="square-js" +await db.dropTable("documents"); +const job = await db.dropTableAsync("documents"); +await db.dropAllTables(); +``` + +```sql SQL +DROP TABLE documents +``` + + + +Dropping removes the table and **every version of it**. +[Versioning](/management/table#versioning) does not survive a drop, and neither +`drop_all_tables` nor `drop_database` asks for confirmation. Both work only on +a local database; on an Enterprise connection the SDK raises instead. + + +On a large table the drop can take a while, so `drop_table_async` returns a +[job](/basics/jobs) rather than blocking when the deployment drops tables in the +background. In the embedded library, and on an Enterprise cluster that drops inline, the +returned job has already finished. + +## Table management APIs {#surface} + +| | Python | TypeScript | SQL | +| --- | --- | --- | --- | +| create | `create_table` | `createTable` | `CREATE TABLE` | +| create empty | `create_table(schema=)` | `createEmptyTable` | `CREATE TABLE` | +| open | `open_table` | `openTable` | -- | +| list | `table_names`, `list_tables` | `tableNames`, `listTables` | -- | +| exists | `table_exists` | -- | -- | +| rename | `rename_table` | `renameTable` | -- | +| clone | `clone_table` | `cloneTable` | -- | +| drop | `drop_table`, `drop_table_async` | `dropTable`, `dropTableAsync` | `DROP TABLE` | +| drop all | `drop_all_tables` | `dropAllTables` | -- | + +## Data types {#data-types} + +A table's schema is an **Arrow schema**: there is no separate LanceDB type +system mapped onto storage, so a column is the same object to the query engine +as it is to the format. + +| Category | Types | +| --- | --- | +| Numeric | `int8`-`int64` and unsigned, `float16`, `float32`, `float64` | +| String and binary | `utf8`, `large_utf8`, `binary`, `large_binary`, `fixed_size_binary(n)` | +| Date and time | `date32`, `date64`, `time32`, `time64`, `timestamp`, `duration` | +| Nested | `struct`, `list`, `large_list`, `fixed_size_list`, `map` | +| Lance extensions | vectors, [JSON](/sql/data-types#json), [blobs](#multimodal), bfloat16 | + +A vector column is a `fixed_size_list`, an ordinary Arrow type, +which is why it is selectable and joinable but why arithmetic over it is list +arithmetic rather than scalar. + +See [SQL data types](/sql/data-types) for the full reference, including the +extension types and pseudo-columns. + +## Multimodal data {#multimodal} + +Binary data (images, audio, video, model artifacts) lives in the table +beside the structured columns and embeddings that describe it, and is governed +by the same versioning and search. + +Small values go in an ordinary `binary` column. Large ones go in a **blob** +column, stored out of line so a scan over the other columns stays fast. See +[Data types](/sql/data-types#blobs) for how the two differ to a reader. + +### Store binary data {#multimodal-store-binary-data} + +To store binary data, define a binary Arrow field in your schema (`pa.binary()` in Python, `Binary` in TypeScript, and `DataType::Binary` in Rust). + +#### 1\. Setup and imports {#multimodal-1-setup-and-imports} + +First, import the necessary libraries for LanceDB and Arrow in your SDK. + + + + {MultimodalImports} + + + + {TsMultimodalImports} + + + + {RsMultimodalImports} + + + +#### 2\. Prepare data {#multimodal-2-prepare-data} + +For this example, we'll create some dummy in-memory images. In a real application, you would read these from files or an API. The key is to convert your data (image, audio, etc.) into a raw `bytes` object. + + + + {CreateDummyData} + + + + {TsCreateDummyData} + + + + {RsCreateDummyData} + + + +#### 3\. Define the schema {#multimodal-3-define-the-schema} + +When creating the table, it is **highly recommended** to define the schema explicitly. This ensures that your binary data is correctly interpreted as a `binary` type by Arrow/LanceDB and not as a generic string or list. + + + + {DefineSchema} + + + + {TsDefineSchema} + + + + {RsDefineSchema} + + + +#### 4\. Ingest data {#multimodal-4-ingest-data} + +Now, create the table using the data and the defined schema. + + + + {IngestData} + + + + {TsIngestData} + + + + {RsIngestData} + + + +### Retrieve and use blobs {#multimodal-retrieve-and-use-blobs} + +When you search your LanceDB table, you can retrieve the binary column just like any other metadata. + + + + {SearchData} + + + + {TsSearchData} + + + + {RsSearchData} + + + +#### Convert bytes back to objects {#multimodal-convert-bytes-back-to-objects} + +Once you have the bytes back from the search result, you can decode them into the original format (for example, an image object or audio buffer). + + + + {ProcessResults} + + + + {TsProcessResults} + + + + {RsProcessResults} + + + +### Managed blobs (Blob v2) {#managed-blobs} + +Use `lancedb.blob()` for images, audio, videos, and other binary values whose +payloads should load separately from the rest of a row. Write Python `bytes` +normally. Set the table schema metadata `lance.blob.managed` to `true` to +store small values inline and larger values in managed objects under the table's `_blobs/` directory. Medium values can share a packed +object; large values use a dedicated object. + +The table owns these objects. You do not upload them separately, keep an object +catalog, or delete their files yourself. A descriptor records where to read the +bytes. Compaction preserves the descriptor and its payload object, so merging +table fragments does not rewrite the blob payloads. + + +Use an SDK and Enterprise deployment that support Blob v2 Managed storage. +Upgrade every reader, writer, and maintenance worker before activating Managed +blobs on a table, and reopen existing table handles after the upgrade. Older +clients cannot safely maintain a table containing Managed blobs. + + +#### Write and read blobs {#managed-blobs-read-write} + +This example uses a local connection. The same schema, `add`, query, and +`fetch_blobs` calls work with an Enterprise database connection: + +```python +import lancedb +import pyarrow as pa + +db = lancedb.connect("./media") +table = db.create_table( + "images", + schema=pa.schema([ + pa.field("id", pa.int64(), nullable=False), + lancedb.blob("image"), + ], metadata={"lance.blob.managed": "true"}), +) +table.add([ + {"id": 1, "image": b""}, + {"id": 2, "image": bytes(range(256)) * 400}, + {"id": 3, "image": None}, +]) + +# Query descriptors first, then fetch only the selected rows' payloads. +hits = ( + table.search() + .where("id <= 2") + .select(["id", "image"]) + .with_row_id(True) + .to_arrow() +) +images = table.fetch_blobs("image", hits).to_pylist() +by_id = dict(zip(hits["id"].to_pylist(), images, strict=True)) +assert by_id[1] == b"" +assert len(by_id[2]) == 102400 +``` + +`None` is a null value; `b""` is a present, empty blob. `fetch_blobs` returns +bytes in the order of the supplied row IDs. It materializes the selected +payloads, so fetch bounded batches when blobs are large. Row IDs belong to +their table; fetch them from the same table and snapshot that produced the +query result. + +Keep descriptors opaque in application code. Their representation can differ +between inline values, Managed objects, and externally referenced blobs. For +streaming and range reads, see the +[Lance blob guide](https://lance.org/guide/blob/). + +#### Derived blobs and maintenance {#managed-blobs-lifecycle} + +Enterprise Functions can consume blob columns and +return new blobs. Their output payloads are managed by the destination table. +Local tables can also derive blob columns with +[SQL computed columns](/feature-engineering/add-computed-column). + +Deleting a row or replacing its blob does not immediately remove the old +payload: retained table versions may still reference it. [Cleanup](/maintenance/cleanup#managed-blobs) +reclaims objects after those references expire. A packed object remains while +any of its contained blobs is still referenced. + +### Legacy large-binary blobs {#multimodal-large-blobs-blob-api} + +The schema below describes the earlier large-binary Blob API. It is distinct +from the `lancedb.blob()` schema above; changing the field's metadata alone does +not migrate an existing column to Blob v2. + +For larger files like high-resolution images or videos, Lance provides a specialized **Blob API**. By using a large-binary Arrow type (`pa.large_binary()` in Python, `LargeBinary` in TypeScript, and `DataType::LargeBinary` in Rust) and specific metadata, you enable **lazy loading** and optimized encoding. This allows you to work with massive datasets without loading all binary data into memory upfront. + +#### 1\. Define a blob schema {#multimodal-1-define-a-blob-schema} + +To use the Blob API, you must mark the column with `{"lance-encoding:blob": "true"}` metadata. + + + + {BlobApiSchema} + + + + {TsBlobApiSchema} + + + + {RsBlobApiSchema} + + + +#### 2\. Ingest large blobs {#multimodal-2-ingest-large-blobs} + +You can then ingest data normally, and Lance will handle the optimized storage. + + + + {BlobApiIngest} + + + + {TsBlobApiIngest} + + + + {RsBlobApiIngest} + + + + +For more advanced usage, including random access and file-like reading of blobs, see the +Lance format's [blob API documentation](https://lance.org/guide/blob/). + + +#### 3\. Convert blob tables to pandas {#multimodal-3-convert-blob-tables-to-pandas} + +When you call `to_pandas()` on a local LanceDB table that contains Blob API columns, the `blob_mode` argument controls how those columns materialize. This is available in the Python SDK on local tables; remote tables raise `NotImplementedError`. + +`blob_mode` accepts: + +- `"lazy"` (default): returns blob columns as lazy `BlobFile` objects without eagerly materializing their payloads. Use this when you want to stream blob bytes on demand or only inspect a subset of rows. Namespace-backed local tables also use the Lance native blob-aware pandas conversion for lazy blobs; in-memory datasets fall back to the standard PyArrow `to_pandas()` path. +- `"bytes"`: eagerly materializes each blob as `bytes`. Use this when you need the raw payload in the DataFrame, for example to decode an image or audio clip in-process. +- `"descriptions"`: returns blob descriptors (offsets, sizes, and positions) instead of the data itself. Use this when you want to plan I/O without paying the cost of loading every blob. + +`"bytes"` is not supported on in-memory tables. + +Extra keyword arguments are forwarded to the underlying PyArrow / Lance pandas conversion, so you can also pass options like `split_blocks` or `self_destruct`: + + + + {BlobApiToPandas} + + + +Query builders also accept `blob_mode` on their `to_pandas()` method: + +- Plain scans support `"lazy"`, `"bytes"`, and `"descriptions"` with filters, projections, aliases, `limit`, and `offset`. +- Vector, FTS, hybrid, and ordered queries can't materialize blob columns through `to_pandas()`; omit blob columns from the projection for those query shapes. +- This works on both sync and async query builders. Extra PyArrow kwargs like `split_blocks` and `self_destruct` are still forwarded. + + + + {QueryToPandasKwargs} + + + +### Other modalities {#multimodal-other-modalities} + +The `pa.binary()` and `pa.large_binary()` types are universal. You can use this same pattern for other types of multimodal data: + +- **Audio:** Read `.wav` or `.mp3` files as bytes. +- **Video:** Store video transitions or full clips using the Blob API. +- **PDFs/Documents:** Store the raw file content for document search. + +### bfloat16 {#multimodal-bfloat16} + +Sixteen-bit floats in the bfloat16 layout, stored as `fixed_size_binary(2)`. +Useful as a vector element type when halving the memory matters more than the +precision does. + +## Schema evolution {#schema} + +Schema evolution enables non-breaking modifications to a database table's structure (such as adding columns, altering data types, or dropping fields) to adapt to evolving data requirements without service interruptions. +LanceDB supports ACID-compliant schema evolution through granular operations (add/alter/drop columns), allowing you to: + +* Iterate Safely: Modify schemas in production with versioned datasets and backward compatibility +* Scale Seamlessly: Handle ML model iterations, regulatory changes, or feature additions +* Optimize Continuously: Remove unused fields or enforce new constraints without downtime + + +In SQL, schema changes are [`ALTER TABLE`](/sql/ddl/table#alter). + + +### Schema evolution operations {#schema-schema-evolution-operations} + +LanceDB supports four primary schema evolution operations: + +1. **Adding new columns**: Extend your table with additional attributes +2. **Altering existing columns**: Change column names, data types, or nullability +3. **Updating field metadata**: Attach or change per-column Arrow metadata +4. **Dropping columns**: Remove unnecessary columns from your schema + + + +Schema evolution operations are applied immediately but do not typically require rewriting all data. However, data type changes may involve more substantial operations. + + +Each schema evolution operation commits a new table version and returns status metadata such as +the committed `version`. Run these operations from a mutable table handle; if you checked out an +older version for reads, call `checkout_latest` / `checkoutLatest` before modifying the schema. + +### Add new columns {#schema-add-new-columns} + +You can add new columns to a table with the [`add_columns`](https://lancedb.github.io/lancedb/python/python/#lancedb.table.Table.add_columns) +method in Python, [`addColumns`](https://lancedb.github.io/lancedb/js/classes/Table/#addcolumns) in TypeScript/JavaScript, or `add_columns` in Rust. +New columns are populated based on SQL expressions you provide. + + +#### Set up the example table {#schema-set-up-the-example-table} + +First, let's create a sample table with product data to demonstrate schema evolution: + + + + {PySchemaAddSetup} + + + + {TsSchemaAddSetup} + + + + {RsSchemaAddSetup} + + + + +Columns derived from existing data (SQL expressions over other columns) are +covered in [Data evolution](/feature-engineering/data-evolution), because +deriving values is a feature-engineering job rather than a schema one. + + +#### Add columns with default values {#schema-add-columns-with-default-values} + +Add boolean columns with default values for status tracking: + + + + {AddColumnsDefaultValues} + + + + {TsAddColumnsDefaultValues} + + + + {RsAddColumnsDefaultValues} + + + +#### Add nullable columns {#schema-add-nullable-columns} + +Add timestamp columns that can contain NULL values: + + + + {AddColumnsNullable} + + + + {TsAddColumnsNullable} + + + + {RsAddColumnsNullable} + + + + +When adding columns that should contain NULL values, be sure to cast the NULL to the appropriate type, e.g., `cast(NULL as timestamp)`. + + +### Alter existing columns {#schema-alter-existing-columns} + +You can alter columns using the [`alter_columns`](https://lancedb.github.io/lancedb/python/python/#lancedb.table.Table.alter_columns) +method in Python, [`alterColumns`](https://lancedb.github.io/lancedb/js/classes/Table/#altercolumns) in TypeScript/JavaScript, or `alter_columns` in Rust. This allows you to: + +- Rename a column +- Change a column's data type +- Modify nullability (whether a column can contain NULL values) + + +#### Set up the example table {#schema-set-up-the-example-table-2} + +Create a table with a custom schema to demonstrate column alterations: + + + + {SchemaAlterSetup} + + + + {TsSchemaAlterSetup} + + + + {RsSchemaAlterSetup} + + + +#### Rename columns {#schema-rename-columns} + +Change column names to better reflect their purpose: + + + + {AlterColumnsRename} + + + + {TsAlterColumnsRename} + + + + {RsAlterColumnsRename} + + + +#### Change data types {#schema-change-data-types} + +Convert column data types for better performance or compatibility: + + + + {AlterColumnsDataType} + + + + {TsAlterColumnsDataType} + + + + {RsAlterColumnsDataType} + + + +#### Make columns nullable {#schema-make-columns-nullable} + +You can alter columns to contain NULL values: + + + + {AlterColumnsNullable} + + + + {TsAlterColumnsNullable} + + + + {RsAlterColumnsNullable} + + + +Changing a column to nullable affects future writes and merges too: missing values are accepted +only when the target column is nullable. + +#### Multiple changes at once {#schema-multiple-changes-at-once} + +Apply several alterations in a single operation: + + + + {AlterColumnsMultiple} + + + + {TsAlterColumnsMultiple} + + + + {RsAlterColumnsMultiple} + + + +#### Expression-based type changes {#schema-expression-based-type-changes} + +For transformations that are not simple casts (for example, converting `"$100"` to an integer), use a SQL-expression column add, then drop and rename: + + + + {AlterColumnsWithExpression} + + + + {TsAlterColumnsWithExpression} + + + + {RsAlterColumnsWithExpression} + + + +#### Alter embedding types and dimensions {#schema-alter-embedding-types-and-dimensions} + +It's quite common to need to change an embedding column's schema, in case a new model becomes available with a different embedding dimension. +- In Python, the example shows an in-place type update when the cast is compatible. +- In TypeScript and Rust, the example shows a dimension change (`384 -> 1024`), which cannot be cast in-place. + +For dimension changes, use this 3-step pattern: add a new column with the target type, drop the old column, then rename the new column to the original name. + + + + {AlterVectorColumn} + + + + {TsAlterVectorColumn} + + + + {RsAlterVectorColumn} + + + + +**`FixedSizeList` Dimension Changes in TypeScript and Rust** + +`alterColumns` / `alter_columns` can cast between compatible types, but changing `FixedSizeList` dimensions (for example `384 -> 1024`) is not a compatible cast. +For such cases, use `addColumns` / `add_columns` (with `arrow_cast`), then `dropColumns` / `drop_columns`, then rename the replacement column. + + + +Changing data types requires rewriting the column data and may be resource-intensive for large tables. Renaming columns or changing nullability is more efficient as it only updates metadata. + + +### Update field metadata {#schema-update-field-metadata} + +Each column in a LanceDB table can carry a small key/value map of Arrow field metadata, which is useful +for annotating columns with units, provenance, PII flags, embedding model versions, or any other +schema-level context your application needs. + +Use [`update_field_metadata`](https://lancedb.github.io/lancedb/python/python/#lancedb.table.Table.update_field_metadata) +in Python, [`updateFieldMetadata`](https://lancedb.github.io/lancedb/js/classes/Table/#updatefieldmetadata) +in TypeScript/JavaScript, or `update_field_metadata` in Rust to add, change, or remove these +key/value pairs without rewriting the column data. Each call commits a new table version and returns +the new `version`. + +Each update targets one field by **dot-path**: top-level columns are addressed by name (for +example `"embedding"`), and nested fields by their full path (for example `"address.zip"`). By +default, the keys you pass are **merged** into the field's existing metadata: keys you do not +mention are preserved, and passing `None` (Python) or `null` (TypeScript) deletes a key. Set +`replace: true` to swap the field's entire metadata map instead of merging. + + + + {SchemaFieldMetadataMerge} + + + + {TsSchemaFieldMetadataMerge} + + + + {RsSchemaFieldMetadataMerge} + + + +To overwrite a field's metadata entirely instead of merging, set `replace` to `true`: + + + + {SchemaFieldMetadataReplace} + + + + {TsSchemaFieldMetadataReplace} + + + + {RsSchemaFieldMetadataReplace} + + + + +You can pass multiple updates in a single call to change metadata on several fields at once. +Each call commits a single new table version. + + +#### Canonical metadata keys {#schema-canonical-metadata-keys} + +You can use any string as a metadata key. By convention, LanceDB treats keys prefixed with +`lancedb:` as canonical. LanceDB Enterprise displays these keys in the UI, and agents can rely +on finding this information in a consistent place. Use them when they fit your use case: + +| Key | Purpose | Example | +| --- | --- | --- | +| `lancedb:description` | Human-readable description of the field. | `"CLIP embedding of the product image"` | +| `lancedb:tag:` | User-defined key/value tag, where the suffix names the tag category. | `"lancedb:tag:model": "clip"` | +| `lancedb:logical-column` | Groups related columns into one logical column. For example, `feature_v1` and `feature_v2` might belong to the same logical column. | `"lancedb:logical-column": "feature"` | +| `lancedb:status` | Life cycle state of the column: `production`, `candidate`, `deprecated`, or `archived`. | `"lancedb:status": "production"` | + + +These keys are conventions, not enforced constraints. LanceDB does not validate their values, +but following the conventions keeps your tables consistent with Enterprise tooling. + + +### Drop columns {#schema-drop-columns} + +You can remove columns using the [`drop_columns`](https://lancedb.github.io/lancedb/python/python/#lancedb.table.Table.drop_columns) + method in Python, [`dropColumns`](https://lancedb.github.io/lancedb/js/classes/Table/#dropcolumns) in TypeScript/JavaScript, or `drop_columns` in Rust. + + +#### Set Up the example table {#schema-set-up-the-example-table-3} + +Create a table with temporary columns that we'll remove: + + + + {SchemaDropSetup} + + + + {TsSchemaDropSetup} + + + + {RsSchemaDropSetup} + + + +#### Drop single columns {#schema-drop-single-columns} + +Remove individual columns that are no longer needed: + + + + {DropColumnsSingle} + + + + {TsDropColumnsSingle} + + + + {RsDropColumnsSingle} + + + +#### Drop multiple columns {#schema-drop-multiple-columns} + +Remove several columns at once for efficiency: + + + + {DropColumnsMultiple} + + + + {TsDropColumnsMultiple} + + + + {RsDropColumnsMultiple} + + + + +Dropping a column changes the latest version only. Until +[cleanup](/maintenance/cleanup) prunes the versions from before the drop, +[restoring](#versioning) one of them brings the column and its values back, +along with the rest of the table as it was then. Once those versions are +pruned, the drop cannot be undone, so check before dropping a column you may +need. + + +## Versioning {#versioning} + +This page shows the core table-versioning APIs used in the code snippets for Python, TypeScript, and Rust. +Each operation below maps directly to methods shown in the examples. + +### Basic Versioning Example {#versioning-basic-versioning-example} + +Let's create a table with sample data to demonstrate LanceDB's versioning capabilities: + +#### Set Up the Table {#versioning-set-up-the-table} + +First, let's create a table with some sample data: + + + + {VersioningBasicSetup} + + + + {TsVersioningBasicSetup} + + + + {RsVersioningBasicSetup} + + + + + + + {RsVersioningMakeQuotesReader} + + + + +#### Check Initial Version {#versioning-check-initial-version} + +After creating the table, let's check the initial version information: + + + + {VersioningCheckInitialVersion} + + + + {TsVersioningCheckInitialVersion} + + + + {RsVersioningCheckInitialVersion} + + + +### Modify Data {#versioning-modify-data} + +When you modify data through operations like update or delete, LanceDB automatically creates new versions. + +#### Update Existing Data {#versioning-update-existing-data} + +Let's update some existing records to see versioning in action: + + + + {VersioningUpdateData} + + + + {TsVersioningUpdateData} + + + + {RsVersioningUpdateData} + + + +#### Add New Data {#versioning-add-new-data} + +Now let's add more records to the table: + + + + {VersioningAddData} + + + + {TsVersioningAddData} + + + + {RsVersioningAddData} + + + +#### Check Version Changes {#versioning-check-version-changes} + +Let's see how the versions have changed after our modifications: + + + + {VersioningCheckVersionsAfterMod} + + + + {TsVersioningCheckVersionsAfterMod} + + + + {RsVersioningCheckVersionsAfterMod} + + + +### Rollback to Previous Versions {#versioning-rollback-to-previous-versions} + +LanceDB supports fast rollbacks to any previous version without data duplication. + +#### View All Versions {#versioning-view-all-versions} + +First, let's see all the versions we've created: + + + + {VersioningListAllVersions} + + + + {TsVersioningListAllVersions} + + + + {RsVersioningListAllVersions} + + + +#### Restore a Version Snapshot {#versioning-restore-a-version-snapshot} + +Now let's restore a captured version snapshot: + + + + {VersioningRollback} + + + + {TsVersioningRollback} + + + + {RsVersioningRollback} + + + +### Tag-Based Versioning {#versioning-tag-based-versioning} + +Numeric table versions like `v3` or `v17` are precise but hard to remember. Tags +let you attach human-readable labels (e.g., `"prod"`, `"baseline"`, +`"q3-evaluation"`) to specific versions and check those out by name. They are +conceptually similar to git tags, and unlike numeric versions, **tagged versions +are never pruned**. A tagged version that is older than the retention window and +is not the latest stops cleanup instead (see the cleanup note at the bottom of this +page). + +The tags API supports the standard CRUD operations (create, list, update, delete), +plus checking out by tag name. + + + + {VersioningTags} + + + + {TsVersioningTags} + + + + {RsVersioningTags} + + + + +Deleting a tag only removes the label, not the version it points to. After +deletion, the underlying table version becomes eligible for cleanup again. + + +### Branches {#versioning-branches} + +Beyond linear history, LanceDB also supports **branches**: isolated, writable +lines of history forked from `main` (or a specific version). Whereas tags and +`checkout` give you read-only views of existing versions, a branch has its own +writable history, making it ideal for experiments, backfills, and migrations +that you want to keep separate from production reads on `main`. + +Branches are covered in their own guide: see [Branches](/tables/branching). + +### Delete Data From the Table {#versioning-delete-data-from-the-table} + +Let's demonstrate how deletions also create new versions: + +#### Go Back to Latest Version {#versioning-go-back-to-latest-version} + +First, let's return to the latest version: + + + + {VersioningCheckoutLatest} + + + + {TsVersioningCheckoutLatest} + + + + {RsVersioningCheckoutLatest} + + + +#### Delete Data {#versioning-delete-data} + +Now let's delete some data to see how it affects versioning: + + + + {VersioningDeleteData} + + + + {TsVersioningDeleteData} + + + + {RsVersioningDeleteData} + + + +#### Version History and Operations {#versioning-version-history-and-operations} + +On a fresh table, the snippets in this guide produce this version sequence: + +1. `v1`: create table (`create_table` / `createTable` / `create_table`) +2. `v2`: update rows (`update`) +3. `v3`: add rows (`add`) +4. `v4`: restore snapshot (`restore`) from `version_after_mod`/`versionAfterMod` +5. `v5`: delete rows (`delete`) + +Read-only and checkout operations shown here (`list_versions`/`listVersions`, `version`, `checkout`, `checkout_latest`/`checkoutLatest`) do not create new versions. + +The version metadata fields can differ by backend. Direct table-backed version listing exposes a +timestamp, while namespace-backed listing may expose fields such as `manifest_path`, +`manifest_size`, `e_tag`, and `timestamp_millis`. In deployments that use managed versioning, +prefer the table version APIs exposed by LanceDB Enterprise or the namespace service instead of +mixing in lower-level Lance file operations. + + +**System Operations** + +System operations like `optimize()`, index updates, and table compaction also increment table version numbers. +In LanceDB OSS, `optimize()` can prune older versions based on its retention setting (`cleanup_older_than`, 7 days by default), +which is when old-version files are removed and disk space is reclaimed. A deployment prunes them in the background +when its configuration enables [cleanup](/maintenance/cleanup); `optimize()` is not available there. + +**Tagged versions are never pruned.** A version with a tag pointing at it is +retained regardless of age. When a tagged version is older than the retention window and +is not the latest, cleanup refuses to run instead of pruning around it: `optimize()` raises +an error naming the tag and prunes nothing. A tag on the latest version does not cause +this, but `optimize()` compacts before it prunes, and compacting commits a new version +whenever it merges files, so a tag on what was the latest version can become an older +one by the time cleanup runs; the error then comes after compacting, and the index +update does not run. To let cleanup proceed, [move the tag](#versioning-tag-based-versioning) +to a version inside the retention window, delete it, or widen the window. + diff --git a/docs/web/management/view.mdx b/docs/web/management/view.mdx new file mode 100644 index 000000000..de6cd38a5 --- /dev/null +++ b/docs/web/management/view.mdx @@ -0,0 +1,34 @@ +--- +title: "Views" +sidebarTitle: "View" +description: "A saved query, evaluated when read.

Hosted rerankers need +provider credentials and make API calls. See [reranking integrations](/integrations/reranking) +for provider setup and model selection; specify a model supported by your provider. + +Rerankers add `_relevance_score` and return rows ordered by descending relevance. Python rerankers +accept a `return_score` option; use `"all"` where supported to keep the +original vector distance or FTS score columns for debugging. Model-based rerankers read from +`column="text"` by default, so either return that column in the search results or pass a different +column. + +`refine_factor` expands the vector index's internal candidate pool and rescores +those candidates using full vectors before keeping the requested limit. It +can improve the candidates available for reranking, but it does not multiply +the final result count. Compare retrieval recall and total query latency. + + +**SDK coverage differs across languages** + +The provider-specific rerankers in the table above +(`CohereReranker`, `CrossEncoderReranker`, `ColbertReranker`, and others under `lancedb.rerankers`) +are currently **Python-only**. The TypeScript and Rust SDKs currently expose hybrid reranking through +the generic `Reranker` interface (`rerankHybrid` / `rerank_hybrid`) and the built-in `RRFReranker`. +In TypeScript, create the built-in RRF reranker with `await RRFReranker.create(k)`. To use a +model-based reranker from TypeScript or Rust, you must implement the hybrid reranker interface +yourself. + + + +### Multi-vector reranking {#multi-vector-reranking} +Use `rerank_multivector()` to combine result sets from several vector queries. +The example below assumes `table` has three vector columns with embedding +metadata and uses a cross encoder to rerank their candidates. + + +```python Python icon="python" +from lancedb.rerankers import CrossEncoderReranker + +reranker = CrossEncoderReranker() + +query = "hello" + +# `deduplicate=True` requires `_rowid` on every input result set, +# so call `.with_row_id(True)` on each search before passing it in. +res1 = table.search(query, vector_column_name="vector").limit(3).with_row_id(True) +res2 = table.search(query, vector_column_name="text_vector").limit(3).with_row_id(True) +res3 = table.search(query, vector_column_name="meta_vector").limit(3).with_row_id(True) + +reranked = reranker.rerank_multivector([res1, res2, res3], deduplicate=True) +``` + + +- Passing `deduplicate=True` to `rerank_multivector(...)` raises a `ValueError` if any of the +input result sets is missing the `_rowid` column. Therefore, it's recommended to add `.with_row_id(True)` to every +`table.search(...)` call before reranking, or omit `deduplicate=True` if you don't need it. +- `RRFReranker.rerank_multivector(...)` always requires `_rowid` on its inputs, regardless of +the `deduplicate` flag. + +## Implement a custom ranking policy {#creating-custom-rerankers} + +Python custom rerankers implement `rerank_hybrid()` and can optionally implement +`rerank_vector()` and `rerank_fts()`. TypeScript and Rust expose hybrid reranking +interfaces. See [the interface requirements](#custom) before implementing one. + +## Algorithm options + +The following sections describe the Python constructor options and examples. +Provider and local-model examples require their additional packages and model +or credential setup. They are separate programs, not steps to concatenate. + +## Reciprocal rank fusion {#rrf} + + + + + + +**Reciprocal Rank Fusion (RRF)** is a model-free way to merge several ranked result lists into a +single ordering. Rather than comparing raw similarity scores (which aren't directly comparable +across, say, a vector search and a full-text search), RRF looks only at each document's *rank +position* in each list. It scores every document with the formula `1 / (rank + K)`, sums those +contributions across the lists, and re-sorts by the total. Documents that rank highly in more than +one search rise to the top. Because there's no model to load or call, it's fast and cheap, which is +why it's the default reranker for LanceDB hybrid search. The implementation follows the +[Cormack et al. paper](https://plg.uwaterloo.ca/~gvcormac/cormacksigir09-rrf.pdf). + +> **Supported query types:** hybrid search and [multi-vector reranking](/reranking#multi-vector-reranking). +> Because RRF fuses two or more ranked lists, it can't rerank a single vector or full-text result set +> on its own. Calling `rerank_vector` or `rerank_fts` on an `RRFReranker` raises `NotImplementedError`. + + + + + {PyRerankingRrfUsage} + + + +### Python arguments {#rrf-accepted-arguments} +| Argument | Type | Default | Description | +| --- | --- | --- | --- | +| `K` | `int` | `60` | A constant used in the RRF formula (default is 60). Larger values reduce the difference in contribution between nearby rank positions. | +| `return_score` | `str` | `"relevance"` | Options are "relevance" or "all". The type of score to return. If "relevance", will return only the `_relevance_score`. If "all", will return all scores from the vector and FTS search along with the relevance score. | + +`K` must be greater than `0`. In TypeScript, construct the built-in reranker with +`await RRFReranker.create(k)` before passing it to `.rerank(...)`. + +### Multi-vector reranking {#rrf-multi-vector-reranking} + +`RRFReranker` can also fuse the results of several vector searches with `rerank_multivector`, applying +the same rank-fusion algorithm across more than two lists. Every input result set must include the +`_rowid` column, so add `.with_row_id(True)` to each `table.search(...)` call before reranking, +otherwise the call raises a `ValueError`. See [multi-vector reranking](/reranking#multi-vector-reranking) +for a full example. + +### Supported Scores for each query type {#rrf-supported-scores-for-each-query-type} +You can specify the type of scores you want the reranker to return. The following are the supported scores for each query type: + +#### Hybrid Search {#rrf-hybrid-search} +|`return_score`| Status | Description | +| --- | --- | --- | +| `relevance` | ✅ Supported | Keeps `_relevance_score` as the score column alongside the selected data columns. | +| `all` | ✅ Supported | Returned rows have vector(`_distance`) and FTS(`_score`) along with Hybrid Search score(`_relevance_score`). | + + + + +## Linear combination {#linear-combination} + + + + + + +> **Note:** This reranker is deprecated.

At a +minimum, you need to implement `rerank_hybrid()`, which is the logic that combines vector and +full-text search results. Beyond that, you can optionally implement `rerank_vector()` and +`rerank_fts()` if you want your reranker to also handle pure vector or pure full-text searches. + +Implement the hooks your query paths call. The base class raises +`NotImplementedError` for vector-only or FTS-only reranking unless you +implement those methods. + +The Python base class exposes hybrid, vector-only, and FTS-only rerank hooks. TypeScript and Rust +currently expose the custom reranker interface for hybrid reranking. In Rust, a custom reranker must +also satisfy the trait bounds `Debug + Send + Sync`. + +### Interface {#custom-interface} + +The `Reranker` base interface comes with a `merge_results()` method that can be used to combine the +results of semantic and full-text search. This is a vanilla merging algorithm that simply concatenates +the results and removes the duplicates without taking the scores into consideration. It only keeps the +first copy of the row encountered. This works well in cases that don't require the scores of semantic +and full-text search to combine the results. If you want to use the scores or want to support +`return_score="all"`, you'll need to implement your own merging algorithm. The base +`return_score` option accepts only `"relevance"` and `"all"`. + +Whichever methods you override, your reranker has one job on the way out: attach a +`_relevance_score` column with the most relevant rows at the top. LanceDB will reject the result +if that column is missing, and downstream `.limit(...)` calls trust the order you return, so +sort descending before handing the table back. + +For vector-only reranking in Python, pass a text query to `.rerank(..., query_string="...")`. +The vector query itself may be numeric, but `rerank_vector(query, vector_results)` still receives +a string query so your reranker can score each candidate against the user's text intent. + +The method contract is: + +| Method | Input | Required output | +|:-------|:------|:----------------| +| `rerank_hybrid` | Query text, vector results and FTS results | A merged Arrow table ordered by descending `_relevance_score` | +| `rerank_vector` | Query text and vector results | An Arrow table ordered by descending `_relevance_score` | +| `rerank_fts` | Query text and FTS results | An Arrow table ordered by descending `_relevance_score` | + +Implement only the single-search hooks your application uses. The base class +raises `NotImplementedError` for those hooks until they are implemented. + +### Extend an existing reranker {#custom-example} + +This class definition extends `CohereReranker` to exclude text patterns after +reranking. It requires the Cohere package and credentials when instantiated. +It can return fewer results because exclusions happen after retrieval; use a +query predicate instead when a metadata filter expresses the same restriction. + + +```python Python icon="python" +from typing import List, Union +import pyarrow as pa +from lancedb.rerankers import CohereReranker + +class ModifiedCohereReranker(CohereReranker): + def __init__(self, filters: Union[str, List[str]], **kwargs): + super().__init__(**kwargs) + filters = filters if isinstance(filters, list) else [filters] + self.filters = filters + + def rerank_hybrid(self, query: str, vector_results: pa.Table, fts_results: pa.Table)-> pa.Table: + combined_result = super().rerank_hybrid(query, vector_results, fts_results) + df = combined_result.to_pandas() + for filter in self.filters: + df = df.query("not text.str.contains(@filter)") + + return pa.Table.from_pandas(df) + + def rerank_vector(self, query: str, vector_results: pa.Table)-> pa.Table: + vector_results = super().rerank_vector(query, vector_results) + df = vector_results.to_pandas() + for filter in self.filters: + df = df.query("not text.str.contains(@filter)") + + return pa.Table.from_pandas(df) + + def rerank_fts(self, query: str, fts_results: pa.Table)-> pa.Table: + fts_results = super().rerank_fts(query, fts_results) + df = fts_results.to_pandas() + for filter in self.filters: + df = df.query("not text.str.contains(@filter)") + + return pa.Table.from_pandas(df) +``` + + +The reranker receives and returns PyArrow tables. Use `to_pandas()` for a +DataFrame transformation and `pa.Table.from_pandas()` to convert the result +back, preserving `_relevance_score` and the desired row order. + + +## Evaluate relevance, latency and cost {#eval} + +Compare rerankers on the same candidate inputs so you can distinguish ranking +changes from retrieval changes. For hybrid retrieval, prepare the text index +and query vectors before collecting those candidates. + +### Reranking strategies {#eval-reranking-strategies} + +Compare these approaches: + +- **Rank fusion:** RRF and MRR combine rank positions from multiple result lists. +- **Score blending:** linear combination mixes normalized vector and text scores. +- **Model-based reranking:** a model scores each query-document pair. + +Hybrid search uses RRF by default. You do not need to call `rerank()` to select +it. Pass a reranker when you want a different algorithm or configuration. + +By default, rerankers return `_relevance_score`. Pass `return_score="all"` when a reranker +supports it, and you also need the original vector or FTS scores for debugging. +Evaluation code can rely on returned rows being ordered by descending `_relevance_score`. Empty +reranked result sets still include the `_relevance_score` column. + +The synchronous Python hybrid `rerank(...)` method also accepts a `normalize` argument that controls how the raw +vector and FTS scores are made comparable before reranking: + +- `normalize="score"` (the default); normalizes the raw vector and FTS scores directly. +- `normalize="rank"`; converts each result list to ranks first, then normalizes. + +Normalization matters for algorithms that use raw scores, such as linear +combination. RRF uses rank positions instead. Compare normalization settings +only when the chosen reranker uses those scores. + +For score-based evaluation, the main built-in knobs are: + +- `RRFReranker(K=60)`: rank fusion with a positive smoothing constant. +- `MRRReranker(weight_vector=0.5, weight_fts=0.5)`: weighted reciprocal rank fusion where the weights must sum to `1.0`. +- `LinearCombinationReranker(weight=0.7, fill=1.0)`: blends vector and FTS scores directly; `fill` controls how strongly to penalize a result missing from one side. + +A result on one dataset does not establish which reranker will work best on +another. Include representative queries and measure both retrieval quality +and ranking quality. + +### Historical evaluation example {#eval-example-evaluation} + +The tables below preserve an earlier experiment comparing multiple rerankers on +~800 hybrid search queries. This is a modified version of an evaluation script by +[LlamaIndex](https://github.com/run-llama/finetune-embedding/blob/main/evaluate.ipynb) that measures +hit-rate \@ top-k.

You do not call `optimize()` +on an Enterprise table. + +## Choose the matching behavior + +| You need | Use | +|:---------|:----| +| Words in any order | A terms query | +| Words in a particular sequence | A [phrase query](#phrase-vs-terms-queries) and an index with token positions | +| Tolerance for typing errors | [Fuzzy search](#fuzzy-search) | +| Parts of words | An [n-gram index](#search-for-substring) | +| Required, optional or excluded terms | [Boolean queries](#boolean-queries) | + +Use a metadata predicate to restrict qualifying records. See +[filtering options](#filtering-options) for prefiltering and postfiltering. +Enterprise SQL provides [`fts()`](/sql/functions#fts) for scored text retrieval. + +## Configure tokenization and matching {#advanced-usage} + +### Tokenize Table Data {#tokenize-table-data} + +The default tokenizer splits text at whitespace and punctuation, lowercases +tokens and removes tokens longer than 40 characters. Stemming, stop-word +removal and accent folding are also enabled by default. + +Stemming is useful for improving search results by reducing words to their root form, e.g. "running" to "run". LanceDB supports stemming for Arabic, Danish, Dutch, English, Finnish, French, German, Greek, Hungarian, Italian, Norwegian, Portuguese, Romanian, Russian, Spanish, Swedish, Tamil, and Turkish. You should set the `base_tokenizer` parameter rather than `tokenizer_name` because you cannot customize the tokenizer if `tokenizer_name` is specified. + +Tokenization and language filters are separate settings. `base_tokenizer` controls how text is split into searchable tokens. `language` controls stemming and stop-word removal when `stem=True` or `remove_stop_words=True`; choose the tokenizer for CJK or mixed-language segmentation. + +For example, to enable stemming for English: + + +```python Python icon="python" +table.create_fts_index("text", language="English", replace=True) +``` + + +Configure tokenization when you create the index. Rebuild the index to change +how existing text is tokenized. + +**Default index parameters:** +- `base_tokenizer`: `"simple"` +- `language`: English +- `with_position`: false +- `max_token_length`: 40 +- `lower_case`: true +- `stem`: true +- `remove_stop_words`: true +- `ascii_folding`: true +- `custom_stop_words`: `None`; pass a `list[str]` to drop additional words beyond the language defaults. Requires `remove_stop_words=True`. + +For multilingual use cases, use `base_tokenizer="icu"` for unicode-aware word segmentation on mixed-language text. ICU stands for [International Components for Unicode](https://icu.unicode.org/). The ICU tokenizer uses bundled ICU4X segmenter data, so it does not require external tokenizer model files. It is a good default when documents mix languages or include scripts where the simple tokenizer would keep an unspaced span as one large token. + +The Python API also supports tokenizer implementations that load language model files. Use `base_tokenizer="jieba/default"` for Jieba tokenization, which segments Chinese text into searchable word tokens when the text is written without spaces between words. Use Lindera-backed tokenizers for dictionary-based East Asian morphological segmentation, such as `base_tokenizer="lindera/ipadic"` for Japanese or `base_tokenizer="lindera/ko-dic"` for Korean when you have installed and compiled that Lindera model.

This small example shows +the mechanics; evaluate retrieval quality with embeddings and queries from +your own application. + + + +## Generate query embeddings automatically {#example-hybrid-search} + +### 1\. Setup {#1-setup} +The following walkthrough uses Sentence Transformers in Python and OpenAI in +TypeScript. Install the corresponding provider packages before starting. +Python downloads a local model; TypeScript calls OpenAI. Install +`lancedb sentence-transformers pandas` for Python, or +`@lancedb/lancedb apache-arrow openai` for TypeScript. Set your OpenAI API key +as described in the [OpenAI embedding setup](/integrations/embedding/openai). +Run the steps for your chosen language in order, choosing one connection option. + + +```python Python icon="python" +import lancedb +from lancedb.index import FTS +from lancedb.rerankers import RRFReranker +from lancedb.embeddings import get_registry +from lancedb.pydantic import LanceModel, Vector +``` + +```typescript TypeScript icon="square-js" +import * as lancedb from "@lancedb/lancedb"; +import "@lancedb/lancedb/embedding/openai"; +import { Utf8 } from "apache-arrow"; +``` + + +### 2\. Connect to LanceDB {#2-connect-to-lancedb} +Choose a local OSS connection or use your Enterprise connection details. + +OSS + + +```python Python icon="python" +uri = "data/sample-lancedb" +db = lancedb.connect(uri) +``` + +```typescript TypeScript icon="square-js" +const databaseDir = "data/sample-lancedb"; +const db = await lancedb.connect(databaseDir); +``` + + +Enterprise + +Replace the placeholders with your Enterprise database URI, API key, region and +endpoint. In application code, load credentials from environment variables or a +secrets manager. + + + + {PyConnectEnterprisePlaceholders} + + + {TsConnectEnterprisePlaceholders} + + + +### 3\. Configure Embedding Model {#3-configure-embedding-model} +Configure the model used for both document and query embeddings. + + +```python Python icon="python" +embeddings = get_registry().get("sentence-transformers").create() +``` + +```typescript TypeScript icon="square-js" +const embedFunc = lancedb.embedding.getRegistry().get("openai")?.create({ + model: "text-embedding-ada-002", +}) as lancedb.embedding.EmbeddingFunction; +``` + + +### 4\. Create Table and Schema {#4-create-table-and-schema} +Define the data structure for your documents, including both the text content and its vector representation. + + +```python Python icon="python" +class Documents(LanceModel): + category: str + text: str = embeddings.SourceField() + vector: Vector(embeddings.ndims()) = embeddings.VectorField() + +table_name = "hybrid_search_example" +table = db.create_table(table_name, schema=Documents, mode="overwrite") +``` + +```typescript TypeScript icon="square-js" +const documentSchema = lancedb.embedding.LanceSchema({ + category: new Utf8(), + text: embedFunc.sourceField(new Utf8()), + vector: embedFunc.vectorField(), +}); + +const tableName = "hybrid_search_example"; +const table = await db.createEmptyTable(tableName, documentSchema, { + mode: "overwrite", +}); +``` + + +### 5\. Add Data {#5-add-data} +Insert sample documents into your table, which will be used for both semantic and keyword search. + + +```python Python icon="python" +data = [ + {"text": "rebel spaceships striking from a hidden base", "category": "film"}, + {"text": "have won their first victory against the evil Galactic Empire", "category": "film"}, + {"text": "during the battle rebel spies managed to steal secret plans", "category": "film"}, + {"text": "to the Empire's ultimate weapon the Death Star", "category": "film"}, +] +table.add(data=data) +``` + +```typescript TypeScript icon="square-js" +const data = [ + { text: "rebel spaceships striking from a hidden base", category: "film" }, + { text: "have won their first victory against the evil Galactic Empire", category: "film" }, + { text: "during the battle rebel spies managed to steal secret plans", category: "film" }, + { text: "to the Empire's ultimate weapon the Death Star", category: "film" }, +]; +await table.add(data); +console.log(`Created table: ${tableName} with ${data.length} rows`); +``` + + +### 6\. Build Full Text Index {#6-build-full-text-index} +Create a full-text search index on the text column to enable keyword-based search capabilities. + + +```python Python icon="python" +table.create_index("text", config=FTS()) +table.wait_for_index(["text_idx"]) +``` + +```typescript TypeScript icon="square-js" +console.log("Creating full-text search index..."); +await table.createIndex("text", { + config: lancedb.Index.fts(), +}); +await table.waitForIndex(["text_idx"], 300); +``` + + +### 7\. Set Reranker [Optional] {#7-set-reranker-optional} +RRF is the default. The examples below configure it explicitly. Other +rerankers and their language support are described in [Reranking](/reranking). + + +```python Python icon="python" +reranker = RRFReranker() +``` + +```typescript TypeScript icon="square-js" +const reranker = await lancedb.rerankers.RRFReranker.create(); +``` + + +### 8\. Hybrid Search {#8-hybrid-search} +Perform a hybrid search query that combines semantic similarity with keyword matching, using the specified reranker to merge and rank the results. + + +```python Python icon="python" +results = ( + table.search( + "rebel spaceships", + query_type="hybrid", + vector_column_name="vector", + fts_columns="text", + ) + .rerank(reranker) + .limit(10) + .to_pandas() +) + +print("Hybrid search results:") +print(results) +``` + +```typescript TypeScript icon="square-js" +console.log("Performing hybrid search..."); +const queryVector = await embedFunc.computeQueryEmbeddings("rebel spaceships"); +const hybridResults = await table + .query() + .fullTextSearch("rebel spaceships") + .nearestTo(queryVector) + .rerank(reranker) + .select(["text"]) + .limit(10) + .toArray(); + +console.log("Hybrid search results:"); +console.log(hybridResults); +``` + + +### 9\. Supply a vector and text separately {#9-hybrid-search-explicit-vector-and-text-query-pattern} +You can supply the vector and text separately. The vector must use the same +model and dimensions as the stored embeddings. This example reuses the model +configured above; the complete example at the top also demonstrates this pattern +in TypeScript and Rust. + + +```python Python icon="python" +text_query = "rebel spaceships" +vector_query = embeddings.compute_query_embeddings(text_query)[0] +( + table.search(query_type="hybrid") + .vector(vector_query) + .text(text_query) + .limit(5) + .to_pandas() +) +``` + + +## Control the candidate results {#query-controls} + +Use a result limit, metadata filters and vector distance bounds to control +which candidates are available to the reranker. The examples below show each +option on the query builder. + + +Set `limit()` to the number of results your application needs. The default is 10. +A larger candidate set can help a reranker find relevant records, but adds work. + + +### Returning row IDs {#returning-row-ids} + +Pass `with_row_id(True)` (Python) or `withRowId()` (TypeScript) to include the internal `_rowid` column in the results. This is useful for joining hybrid results back to a primary table, or for deduping across multiple queries: + + +```python Python icon="python" +results = ( + table.search("rebel spaceships", query_type="hybrid") + .with_row_id(True) + .limit(10) + .to_pandas() +) +# results now contains a `_rowid` column alongside `_relevance_score` +``` + +```typescript TypeScript icon="square-js" +const results = await table + .query() + .fullTextSearch("rebel spaceships") + .nearestTo(queryVector) + .withRowId() + .limit(10) + .toArray(); +``` + + +### Bounding vector distance {#bounding-vector-distance} + +`distance_range(lower, upper)` (Python) and `distanceRange(lower, upper)` (TypeScript) constrain the vector half of the hybrid query to the half-open interval `[lower, upper)`. This is helpful when you want to cap how far semantic candidates can drift from the query vector before reranking: + + +```python Python icon="python" +results = ( + table.search("rebel spaceships", query_type="hybrid") + .distance_range(lower_bound=0.0, upper_bound=0.4) + .limit(10) + .to_pandas() +) +``` + +```typescript TypeScript icon="square-js" +const results = await table + .query() + .fullTextSearch("rebel spaceships") + .nearestTo(queryVector) + .distanceRange(0.0, 0.4) + .limit(10) + .toArray(); +``` + + +Either bound can be omitted to leave that side unbounded. + +### Prefilter vs. postfilter {#prefilter-vs-postfilter} + +A hybrid query applies its metadata filter to both the vector and full-text +searches. Prefiltering, the default, restricts eligible rows before retrieval. +Postfiltering removes candidates after retrieval and can leave fewer results +than requested. See [Filtering](/search/filtering). + + +```python Python icon="python" +# Prefilter (default): filter applied before scoring +table.search("rebel spaceships", query_type="hybrid") \ + .where("category = 'film'", prefilter=True) \ + .limit(10) \ + .to_pandas() + +# Postfilter: filter applied after the sub-queries return top-k +table.search("rebel spaceships", query_type="hybrid") \ + .where("category = 'film'", prefilter=False) \ + .limit(10) \ + .to_pandas() +``` + +```typescript TypeScript icon="square-js" +// Prefilter (default): just call .where(...) +await table.query() + .fullTextSearch("rebel spaceships") + .nearestTo(queryVector) + .where("category = 'film'") + .limit(10) + .toArray(); + +// Postfilter: chain .postfilter() after .where(...) +await table.query() + .fullTextSearch("rebel spaceships") + .nearestTo(queryVector) + .where("category = 'film'") + .postfilter() + .limit(10) + .toArray(); +``` + + +In Python, use [`explain_plan`](/search/explain#analyzing-non-vector-queries) on a hybrid query to see whether the filter pushed into the scan or ran as a separate `FilterExec` step. + +## Choose and evaluate a reranker {#more-on-reranking} + +Start with RRF, then compare alternatives on representative queries. Review +which relevant rows reach the candidate set before evaluating how a reranker +orders them. Record latency as well as relevance: increasing candidate counts +or applying a model-based reranker adds work. + +Reranking runs in the application for both OSS and Enterprise connections. +See [Reranking](/reranking) for model-free fusion, model-based rerankers, +custom implementations and score interpretation. + +In synchronous Python, `.rerank(...)` accepts a reranker and a `normalize` +option (`"score"` or `"rank"`). Normalization matters for methods that blend +raw scores; RRF uses rank positions. These are Python query options, not a +shared signature across every SDK. diff --git a/docs/web/search/index.mdx b/docs/web/search/index.mdx new file mode 100644 index 000000000..9d439b204 --- /dev/null +++ b/docs/web/search/index.mdx @@ -0,0 +1,118 @@ +--- +title: Search +sidebarTitle: Overview +description: "Choose vector, full-text or hybrid search and return the records your application needs." +icon: "list" +availability: + oss: available + enterprise: available + summary: >- + Vector, full-text and hybrid search are available in OSS and Enterprise. +--- + +import { PyVectorSearch, TsVectorSearchBody, TsVectorSearchTail } from '/snippets/search_examples.mdx'; +import { RsExampleBody as RsVectorSearchBody, RsExampleTail as RsVectorSearchTail } from '/snippets/search_vector_search.mdx'; + +LanceDB supports vector, full-text and hybrid search.

Choose the metric +recommended by your embedding model. Use the same metric when building an index +and querying it. + +LanceDB supports `l2`, `cosine`, `dot` and `hamming`. An unindexed search uses +`l2` by default; Hamming distance is for binary vectors. The table below shows +the value returned in the `_distance` column. Smaller values rank first. + +| Distance metric | Mathematical form | Notes | +|---|---|---| +| `l2` | $\sum_i (x_i-y_i)^2$ | Squared Euclidean distance returned in `_distance`. | +| `cosine` | $1-\frac{x\cdot y}{\|x\|_2\|y\|_2}$ | Measures directional difference between vectors. Insensitive to nonzero scaling of vectors. | +| `dot` | $1-\sum_i x_i y_i$ | Dot-product distance. For unit-normalized vectors, this equals cosine distance. | +| `hamming` | $\underset{i}{\sum} \,\: \mathbf{1}_{\, [x_i\neq y_i]}$ | Counts the number of bitwise-differing bits between binary vectors. | + +For indexed search, supported distance metrics vary by index type: + +| Index type | Supported distance metrics | +|---|---| +| `IVF_FLAT` | `["l2", "cosine", "dot", "hamming"]` | +| `IVF_PQ` | `["l2", "cosine", "dot"]` | +| `IVF_SQ` | `["l2", "cosine", "dot"]` | +| `IVF_RQ` | `["l2", "cosine", "dot"]` | +| `IVF_HNSW_FLAT` | `["l2", "cosine", "dot"]` | +| `IVF_HNSW_PQ` | `["l2", "cosine", "dot"]` | +| `IVF_HNSW_SQ` | `["l2", "cosine", "dot"]` | + +### Configure Distance Metric + +Without a vector index, searches use `l2` by default. You can specify `cosine` or +`dot` instead (`hamming` is supported for `IVF_FLAT` indexes only). + +When a vector index exists, the search metric must match the metric used to build +the index. If you explicitly request a different metric, LanceDB cannot use that +index and falls back to an exhaustive (brute-force) search. On LanceDB Cloud, the +brute-force KNN safety limit can reject that search on a large table instead of +executing it. LanceDB Enterprise doesn't have the limit. + +If you omit the search metric, current SDKs use the index metric when an index is +available. Some older SDK versions sent `l2` when the metric was omitted; with a +non-`l2` index, explicitly set the matching metric or upgrade the SDK. + + + +{ConfigureDistanceMetric} + + + +{TsSearch2} + + + +{RsConfigureDistanceMetric} + + + +These examples use cosine distance and return up to ten matches. If the table +has a vector index, build it with the same metric. + +Set `.limit(...)` on vector searches you run in applications. You can page through results with `.offset(...)` and include LanceDB's internal row id with `.with_row_id()` / `.withRowId()` when an operation requires internal row IDs. Use your own ID column for application identifiers. + +## Selecting the vector column + +If your table has exactly one vector column, you can omit the column name and LanceDB will pick it for you. This works for both top-level columns (such as `vector`) and vector fields nested inside a struct (such as `image.embedding`). + +When LanceDB can't infer a single column, it raises a `ValueError` (Python) or rejects the query (Node/Rust). Two cases trigger this: + +- No vector column: the schema has no `fixed_size_list` or `list` of floats. +- Multiple candidates: more than one column matches the query's dimension. The error lists every candidate path so you can pick one explicitly. + +To disambiguate, pass the field path with dot notation. Wrap any segment that contains characters outside `[A-Za-z0-9_]` in backticks (for example, `` `image-meta`.`embedding.v1` ``). + + + +{SelectVectorColumn} + + + +{TsSelectVectorColumn} + + + +The same field-path syntax works when creating an index on a nested vector column: + + + +{IndexNestedColumn} + + + +{TsIndexNestedColumn} + + + +When several columns share a name across structs (for example, `image.embedding` and `text.embedding`), LanceDB still picks the one whose dimension matches your query vector. If two candidates have the same dimension, you must pass the column name explicitly. + +## Search with a vector index {#vector-search-with-ann-index} + +An approximate nearest-neighbor (ANN) index narrows the set of vectors examined +for a query. It can reduce query latency, but may miss neighbors that an +exhaustive search would find. Compare recall and latency on queries that +represent your application before choosing an index and its search settings. + + +When a vector index is used, `_distance` is not always the true distance between full vectors. On quantized ANN indexes, LanceDB may compute `_distance` from the compressed representation for speed. Use `refine_factor` when you want reranking on full vectors. + + +### Exact vs Approximate Distances + +When doing vector search, the meaning of "distance" depends on whether you are using an index and whether `refine_factor` is specified as part of your query. +`nprobes` controls how many partitions are searched to find candidates, `approx_mode` controls the query-time speed/recall trade-off for RQ-quantized indexes, and `refine_factor` controls how many candidates are rescored on full vectors for better distance fidelity and reranking quality. + +The table below summarizes the behavior of `_distance` in search results based on your query configuration: + +| Query mode | Neighbor quality | `_distance` in results | +| :--- | :--- | :--- | +| No index or `.bypass_vector_index()` | Exact kNN (100% recall) | True distance on full vectors | +| Indexed ANN, no `refine_factor` | Approximate neighbors | Distance on the index representation: exact for flat indexes, approximate for quantized indexes | +| Indexed ANN + `refine_factor(1)` | Approximate neighbors (same candidate set) | Distances recomputed on full vectors for reranked candidates | +| Indexed ANN + `refine_factor(>1)` | Better recall than no refine (usually) | Distances recomputed on full vectors for reranked candidates | + + + +{ExactVsApproximateDistances} + + + +{TsExactVsApproximate} + + + +{RsExactVsApproximate} + + + +See [vector indexes](/indexing/vector-index) for index configuration. The +following sections cover query-time settings. + +### Tuning `approx_mode` + +Use `approx_mode` when you want to adjust the speed/recall trade-off for approximate vector search at query time. This setting currently applies only to RQ-quantized indexes, such as `IVF_RQ`; other index types ignore it. + +The supported values are: + +| Value | Behavior | +| :--- | :--- | +| `fast` | Prefer lower query latency, which can reduce recall. | +| `normal` | Use the default balance between query latency and recall. This only has an effect for RQ indexes built with `num_bits > 1`. | +| `accurate` | Prefer higher recall, which can increase query latency. | + +Only the Rust SDK sets `approx_mode`; the Python and TypeScript SDKs do not expose it. You can change `approx_mode` per query without rebuilding the index. For RQ indexes built with `num_bits=1`, `normal` uses the same one-bit scoring path as `fast`. If you also set `refine_factor`, LanceDB first uses `approx_mode` while finding candidates, then reranks the selected candidates on full vectors. + +### Tuning `nprobes` + +- `nprobes` controls how many partitions are searched at query time. +- `nprobes` improves candidate recall, but does not by itself make `_distance` exact. +- The default probe selection is a starting point. Measure recall and latency for your data before overriding it. +- In most cases, leave `nprobes` unset and use the auto-tuned value. +- Only tune `nprobes` manually when recall is below your target, or when you need even higher performance for your workload. +- If recall is too low, increase `nprobes` gradually, but after a certain threshold, increasing `nprobes` yields only marginal accuracy gains. +- If you need higher performance and have recall headroom, decrease `nprobes` gradually. + +For filtered ANN searches, you can also set `minimum_nprobes` and `maximum_nprobes`. LanceDB starts +with the minimum and can scan more partitions up to the maximum if the filter leaves too few +candidates. Calling `nprobes(n)` fixes both values to `n`, which disables that adaptive behavior. +Whether a deployment honors this range depends on its version; one that does not searches exactly +`minimum_nprobes` partitions. + +### Vector Search with Prefiltering + +This is the default vector search setting. You can use prefiltering to boost query performance by reducing the search space before vector calculations begin. The system first applies your filter criteria to the dataset, then conducts vector search operations only on the remaining relevant subset. + + + +{VectorSearchPrefilter} + + + +{TsVectorSearchPrefilter} + + + +{RsVectorSearchPrefilter} + + + +The filter limits which rows can match. Use `select()` to choose the returned +columns and `limit()` to set the maximum number of results. + +### Vector Search with Postfiltering + +Postfiltering selects vector-search candidates before applying the metadata +predicate. It can return fewer matches than requested, even when other rows in +the table satisfy the predicate. Use prefiltering when you want the nearest +records within the matching subset. + + + +{VectorSearchPostfilter} + + + +{TsVectorSearchPostfilter} + + + +{RsVectorSearchPostfilter} + + + +Only retrieved candidates that satisfy the predicate remain in the result. +Increase the candidate limit or use prefiltering if too few records are returned. + + +[Post-filtering](/search/filtering/#post-filtering-with-vector-search) in LanceDB applies +the filter condition after obtaining the nearest neighbors based on vector similarity. + + +## Multivector Search + +Use multivector search when your documents contain multiple embeddings and you need sophisticated matching between query and document vector pairs. The late interaction approach finds the most relevant combinations across all available embeddings and provides nuanced similarity scoring. + +Only `cosine` similarity is supported as the distance metric for multivector search operations. +Every query vector must match the inner dimension of the multivector column. + + + +{MultivectorSearch} + + + +Here you can see how to take 2 query vectors and find the best matching pairs between them and document vectors using late interaction. The `np.random.random(size=(2, 256))` creates a 2×256 array with two random query vectors, `.limit(5)` returns the top 5 best document-query combinations, and `.to_pandas()` provides results in a DataFrame format. + +**Read more:** [Multivector search walkthrough](#multivector) + +## Advanced Search Scenarios + +### Search With Distance Range + +Use `distance_range` search when you need vectors within particular similarity bounds rather than just the closest neighbors. The system filters results to only include vectors that fall within your specified distance thresholds from the query. + + + +{SearchDistanceRange} + + + +{TsDistanceRange} + + + +{RsSearchDistanceRange} + + + +This shows three ways to search within distance ranges: bounded, upper bound only, and lower bound only. + +The `distance_range()` method filters results by similarity thresholds - the first example finds vectors with distance between `0.1` and `0.5`, the second finds vectors closer than `0.5`, and the third finds vectors farther than `0.1`. + + Each approach returns Arrow tables with vectors that fall within your specified distance thresholds. + +### Search With Binary Vectors + +Use binary vector search for scenarios involving binary embeddings, such as those produced by hashing algorithms. The system stores these efficiently as packed uint8 arrays and uses Hamming distance calculations to determine vector similarity. + + +The number of dimensions of the binary vector must be a multiple of 8. A vector of dimensionality 128 will be stored as a `uint8` array of size 16. + + + + +{SearchBinaryVectors} + + + +{TsBinarySearch} + + + +{RsBinarySearch} + + + +Here you can see how to set up a table for binary vectors, pack them efficiently into bytes, and search using Hamming distance. + +The schema defines a 32-byte vector field (256 bits ÷ 8), `np.random.randint(0, 2, size=256)` creates binary vectors, `np.packbits()` compresses them to bytes, and `.distance_type("hamming")` specifies `hamming` distance for similarity calculation. + +The search produces an Arrow table with binary vectors ranked by how many bits differ from the query. + +## Scaling Vector Search + +### Query multiple vectors in a batch {#batch-search} + +Batch search accepts multiple query vectors in one request. The `query_index` +column identifies which query produced each result. Measure throughput and +latency with your workload when choosing a batch size. + + + +{BatchSearch} + + + +{TsBatchSearch} + + + +{RsBatchSearch} + + + +Each input vector has its own nearest-neighbor results. Use `query_index` to +associate each row with the corresponding input vector. + +### Include or skip unindexed rows {#search-with-asynchronous-indexing} + +To optimize for speed over completeness, enable the `fast_search` flag in your query to skip searching unindexed data. + +By default, search includes both indexed vectors and unindexed rows visible to +the query. LanceDB scans the unindexed rows directly. `fast_search` skips that +scan, which can reduce query time but omit recent records. + + + +{FastSearch} + + + +{TsFastSearch} + + + +{RsFastSearch} + + + +Use this option only when results from indexed data are sufficient. + +## Search without a vector index {#brute-force-search} + +### Search With No Index + +The simplest way to perform vector search is to perform a brute force search, without an index, where the distance between the query vector and all the vectors in the database are computed, with the top-k closest vectors returned. + +This is equivalent to a k-nearest neighbours (kNN) search in vector space. + +Choose brute force search when you need guaranteed 100% recall, typically with smaller datasets where query speed isn't the primary concern. The system scans every vector in the table and calculates precise distances to find the exact nearest neighbors. + + + +{BruteForceSearch} + + + +{TsBruteForceSearch} + + + +{RsBruteForceSearch} + + + +These queries return the three nearest matches. Without a vector index, LanceDB +calculates distances directly from the stored vectors. + +![](/static/assets/images/search/knn_search.png) + +Exhaustive search does more work as the table grows. When query latency becomes +too high, add an ANN index and compare its results with the exhaustive baseline. + +### Bypass the Vector Index + +Use `bypass_vector_index` to get exact, ground-truth results by performing exhaustive searches across all vectors. Instead of relying on approximate methods, the system directly compares your query against every vector in the table, ensuring 100% recall at the cost of increased query time. + + + +{BypassVectorIndex} + + + +{TsBypassVectorIndex} + + + +{RsBypassVectorIndex} + + + +This skips the approximate index and checks every single vector for exact, ground-truth results. + +The `.bypass_vector_index()` method forces LanceDB to perform an exhaustive search through all vectors instead of using the approximate nearest neighbor index, ensuring exact results but at the cost of slower performance. + +The query returns the nearest five rows within its filters and distance bounds. +Use an exhaustive scan as a baseline when measuring ANN recall. + +This approach is particularly useful when: +- Evaluating ANN index quality +- Calculating recall metrics to tune index parameters +- Ensuring exact results for critical applications + +## Multi-vector search {#multivector} + +LanceDB's multivector support enables you to store and search multiple vector embeddings for a single item. + +This capability is particularly valuable when working with late-interaction models like ColBERT and ColPaLi, which generate multiple embeddings per document. + +In this tutorial, you'll create a table with multiple vector embeddings per document and learn how to perform multivector search. For more end-to-end examples, see the [VectorDB recipes repository](https://github.com/lancedb/vectordb-recipes/tree/main/examples). + +### Multivector Support + +Each item in your dataset can have a column containing multiple vectors, which LanceDB can efficiently index and search. When performing a search, you can query with either a single vector embedding or multiple vector embeddings. + + +Currently, only the `cosine` metric is supported for multivector search. The vector value type can be `float16`, `float32`, or `float64`. + + +Each query vector must match the inner vector dimension in the multivector column. This applies to both single-vector queries and multi-vector query matrices. + +### Computing Similarity + +MaxSim (Maximum Similarity) is a key concept in late-interaction models that: + +- Computes the maximum similarity between each query embedding and all document embeddings +- Sums these maximum similarities to get the final relevance score +- Effectively captures fine-grained semantic matches between query and document tokens + +The MaxSim calculation can be expressed as: + +$$ +\text{MaxSim}(Q, D) = \sum_{i=1}^{|Q|} \max_{j=1}^{|D|} \text{sim}(q_i, d_j) +$$ + +Where $sim$ is the similarity function (e.g., cosine similarity). + +$$ +Q = \{q_1, q_2, ..., q_{|Q|}\} +$$ + +$Q$ represents the query embeddings, and $D = \{d_1, d_2, ..., d_{|D|}\}$ represents the document embeddings. + +### Using Multivector Search + +#### 1. Setup + +Connect to LanceDB and import the required libraries. + + +```python Python icon="python" +import lancedb +import numpy as np +import pyarrow as pa + +db = lancedb.connect( + uri="db://your-project-slug", + api_key="your-api-key", + region="your-region" +) +``` + + +#### 2. Define Schema + +Define a schema that specifies a multivector field. A multivector field is a nested list structure in which each document contains multiple vectors. In this case, we'll create a schema with: + +1. An ID field as an integer (int64) +2. A vector field that is a list of lists of float32 values + - The outer list represents multiple vectors per document + - Each inner list is a 256-dimensional vector + - Using float32 for memory efficiency while maintaining precision + + +```python Python icon="python" +db = lancedb.connect("data/multivector_demo") +schema = pa.schema( + [ + pa.field("id", pa.int64()), + # float16, float32, and float64 are supported + pa.field("vector", pa.list_(pa.list_(pa.float32(), 256))), + ] +) +``` + + +#### 3. Generate Multivectors + +Generate sample data where each document contains multiple vector embeddings, which can represent different aspects or views of the same document. + +In this example, we create **1024 documents** where each document has **2 random vectors** of **dimension 256**, simulating a real-world scenario where you might have multiple embeddings per item. + + +```python Python icon="python" +data = [ + { + "id": i, + "vector": np.random.random(size=(2, 256)).tolist(), # Each document has 2 vectors + } + for i in range(1024) +] +``` + + +#### 4. Create a Table + +Create a table with the defined schema and sample data, which will store multiple vectors per document for similarity search. + + +```python Python icon="python" +tbl = db.create_table("multivector_example", data=data, schema=schema) +``` + + +#### 5. Build an Index + +Only cosine similarity is supported for multivector search operations. +For faster search, build the standard `IVF_PQ` index over your vectors: + + +```python Python icon="python" +tbl.create_index(metric="cosine", vector_column_name="vector") +``` + + + +**Indexing matters more for multivector tables than for single-vector ones.** + +A brute-force scan over a multivector column has to compare every query vector to every document vector in every row, so the cost grows with both the row count and the number of vectors per row. +In LanceDB OSS, the query will just run, so a large unindexed multivector table can stall a process for a long time before returning results. + +On LanceDB Cloud, the brute-force KNN safety check applies a stricter row threshold to multivector columns; roughly 10× lower than for single-vector columns. So an unindexed multivector table can be rejected with a "vector search would use brute-force KNN" error well before a comparable single-vector table would. LanceDB Enterprise doesn't have the limit. Build the index before you start hitting it from production traffic, even if the dataset is small enough that you'd skip indexing for a single-vector workload. + + +#### 6. Query a Single Vector + +When searching with a single query vector, it will be compared against all vectors in each document, and the similarity scores will be aggregated to find the most relevant documents. + + +```python Python icon="python" +query = np.random.random(256) +results_single = tbl.search(query).limit(5).to_pandas() +``` + + +#### 7. Query Multiple Vectors + +With multiple query vectors, LanceDB calculates similarity using late interaction, a late-interaction technique that computes relevance by finding the best-matching pairs between query and document vectors. This approach provides more nuanced matching while maintaining fast retrieval speeds. + + +```python Python icon="python" +query_multi = np.random.random(size=(2, 256)) +results_multi = tbl.search(query_multi).limit(5).to_pandas() +``` + + + +Visit the [Hugging Face embedding integration](/integrations/embedding/huggingface/) page for information on embedding models. + +### Simple Example: ColBERT Embeddings + +[ColBERT](https://arxiv.org/abs/2004.12832) is the most well-known late-interaction retrieval model that +represents each document and query as multiple token embeddings and scores matches by taking the best +token-to-token similarities (MaxSim) across them. + +Install the dependencies before running this example: + +```bash +pip install pylate lancedb pandas +``` + + +```python Python icon="python" +import numpy as np +import pyarrow as pa +import lancedb +from pylate import models + +## 1) Load a late-interaction model via PyLate +## PyLate docs show ColBERT() + encode(..., is_query=...) +model = models.ColBERT(model_name_or_path="lightonai/GTE-ModernColBERT-v1") + +## You can discover dim from one embedding (avoid guessing) +dim = model.encode(["hello"], is_query=True)[0].shape[1] + +## 2) Create a LanceDB table with a multivector column +db = lancedb.connect("./pylate_lancedb") +schema = pa.schema([ + pa.field("doc_id", pa.string()), + pa.field("text", pa.string()), + # multivector: list> + pa.field("mv", pa.list_(pa.list_(pa.float32(), dim))), +]) + +docs = [ + {"doc_id": "1", "text": "The train to Tokyo leaves at 5pm."}, + {"doc_id": "2", "text": "That Pho restaurant in Hanoi is highly rated."}, + {"doc_id": "3", "text": "This is a noodle bar in Osaka, Japan."}, +] + +## 3) Encode documents with PyLate (token vectors per doc) +doc_texts = [d["text"] for d in docs] +doc_embs = model.encode(doc_texts, is_query=False) # list/array of (T, dim) per doc + +rows = [] +for d, emb in zip(docs, doc_embs): + emb = np.asarray(emb, dtype=np.float32) + rows.append({**d, "mv": emb.tolist()}) + +tbl = db.create_table("docs", data=rows, schema=schema, mode="overwrite") + +## 4) Build an index + query using a query matrix. +## Multivector brute-force scales with rows × vectors-per-row, so build the index +## at much smaller dataset sizes than you would for single-vector search; and +## always before exposing the table to remote traffic. +tbl.create_index(vector_column_name="mv", metric="cosine") + +query = "Tell me about ramen in Japan" +q_emb = np.asarray(model.encode([query], is_query=True)[0], dtype=np.float32) # (Tq, dim) + +out = tbl.search(q_emb).limit(5).to_pandas() # multivector search accepts a matrix +print(out[["doc_id", "text"]]) +``` + + +Late-interaction model implementations evolve rapidly, so it's a good idea to check the latest popular models +when trying multivector search. + +### Advanced Example: XTR Embeddings + +[ConteXtualized Token Retriever (XTR)](https://arxiv.org/abs/2304.01982) is a late-interaction retrieval model that represents text as token-level vectors instead of a single embedding. +This lets search score token-to-token matches (MaxSim), which can improve fine-grained relevance. + +The notebook linked below shows how to integrate XTR, which prioritizes critical document +tokens during the initial retrieval stage and removes the gathering stage to improve performance significantly. +By focusing on the most semantically salient tokens early in the process, XTR reduces computational complexity +while improving recall and ensuring rapid identification of candidate documents. + + + diff --git a/docs/web/snippets/ann_indexes.mdx b/docs/web/snippets/ann_indexes.mdx new file mode 100644 index 000000000..ef4021e16 --- /dev/null +++ b/docs/web/snippets/ann_indexes.mdx @@ -0,0 +1,12 @@ +{/* Auto-generated by scripts/mdx_snippets_gen.py.

Other supported vector element types are +possible; inspect the column with [`arrow_typeof`](/sql/scalar-functions#type) rather than assuming Float32. +It is selectable and testable for nullness: + +```sql +SELECT id FROM documents WHERE vector IS NOT NULL +``` + + +A list representation does not imply that ordinary arithmetic operators +perform vector arithmetic. Use supported distance functions for similarity +calculations. SQL vector search depends on the Enterprise server version and query +plan; see [SQL](/basics/sql#no-vector-sql). + + +### JSON {#json} + +Stored as JSONB in `large_binary` with the `lance.json` extension name. It reads +through accessor functions rather than a `->` operator: + +```sql +SELECT json_get_string(data, 'name') FROM events +WHERE json_get_int(data, 'status') = 200 +``` + +`json_get`, its typed variants, and `json_extract` are **index-accelerated** by a +JSON scalar index. See [Functions](/sql/scalar-functions#json). + +### Blobs {#blobs} + +A blob column is read either as its binary contents or as a **description**: a +pointer plus metadata, without fetching the bytes. That choice changes the +column's Arrow type, and therefore the schema your query sees. + + +The default reads blob columns as descriptions and other binary columns as +binary. A query selecting a blob column and expecting bytes gets a struct. + + +### bfloat16 {#bfloat16} + +Sixteen-bit floats in the bfloat16 layout, stored as `fixed_size_binary(2)`. +Useful as a vector element type when halving the memory matters more than the +precision does. + +## Geospatial {#geospatial} + + +Lance defines geospatial types and `st_*` functions on +[GeoArrow](https://geoarrow.org), but they sit behind an optional build feature +that **LanceDB does not ship**. Calling `st_intersects` and friends returns an +error naming the missing feature rather than an unknown-function error, and the +spatial index is gated the same way. + + +Geometry can still be stored (it is binary, and binary columns work), but +nothing interprets it. Filter on a bounding box held in ordinary numeric +columns if you need spatial predicates today. + +## Pseudo-columns {#pseudo-columns} + +Availability depends on the SQL table provider. The ordinary table provider +exposes the stored dataset schema; naming a Lance scan metadata field does +not make it available as a SQL column. The `fts()` provider adds `_score` to +its schema, so `_score` is included in `SELECT * FROM fts(...)`. + +| Column | Type | | +| --- | --- | --- | +| `_rowid` | `UInt64` | Lance scan row identifier; stability requires stable row ids | +| `_rowaddr` | `UInt64` | physical row address | +| `_rowoffset` | `UInt64` | offset within the fragment | +| `_score` | `Float32` | relevance, from [`fts()`](/sql/functions#fts) | + +`_rowid`, `_rowaddr`, and `_rowoffset` describe Lance scan metadata, not +columns automatically registered on an ordinary SQL table.

    +
    +   1. Definitions.

    +      control with that entity. For the purposes of this definition,
    +      "control" means (i) the power, direct or indirect, to cause the
    +      direction or management of such entity, whether by contract or
    +      otherwise, or (ii) ownership of fifty percent (50%) or more of the
    +      outstanding shares, or (iii) beneficial ownership of such entity.
    +
    +      "You" (or "Your") shall mean an individual or Legal Entity
    +      exercising permissions granted by this License.

    +      source, and configuration files.
    +
    +      "Object" form shall mean any form resulting from mechanical
    +      transformation or translation of a Source form, including but
    +      not limited to compiled object code, generated documentation,
    +      and conversions to other media types.
    +
    +      "Work" shall mean the work of authorship, whether in Source or
    +      Object form, made available under the License, as indicated by a
    +      copyright notice that is included in or attached to the work
    +      (an example is provided in the Appendix below).
    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications
    +      represent, as a whole, an original work of authorship. For the purposes
    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including
    +      the original version of the Work and any modifications or additions
    +      to that Work or Derivative Works thereof, that is intentionally
    +      submitted to Licensor for inclusion in the Work by the copyright owner
    +      or by an individual or Legal Entity authorized to submit on behalf of
    +      the copyright owner. For the purposes of this definition, "submitted"
    +      means any form of electronic, verbal, or written communication sent
    +      to the Licensor or its representatives, including but not limited to
    +      communication on electronic mailing lists, source code control systems,
    +      and issue tracking systems that are managed by, or on behalf of, the

    +      designated in writing by the copyright owner as "Not a Contribution."
    +
    +      "Contributor" shall mean Licensor and any individual or Legal Entity
    +      on behalf of whom a Contribution has been received by Licensor and
    +      subsequently incorporated within the Work.
    +
    +   2. Grant of Copyright License. Subject to the terms and conditions of
    +      this License, each Contributor hereby grants to You a perpetual,
    +      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
    +      copyright license to reproduce, prepare Derivative Works of,
    +      publicly display, publicly perform, sublicense, and distribute the
    +      Work and such Derivative Works in Source or Object form.
    +
    +   3. Grant of Patent License. Subject to the terms and conditions of

    +      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
    +      (except as stated in this section) patent license to make, have made,
    +      use, offer to sell, sell, import, and otherwise transfer the Work,
    +      where such license applies only to those patent claims licensable
    +      by such Contributor that are necessarily infringed by their
    +      Contribution(s) alone or by combination of their Contribution(s)
    +      with the Work to which such Contribution(s) was submitted. If You
    +      institute patent litigation against any entity (including a
    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate
    +      as of the date such litigation is filed.
    +
    +   4. Redistribution. You may reproduce and distribute copies of the
    +      Work or Derivative Works thereof in any medium, with or without
    +      modifications, and in Source or Object form, provided that You
    +      meet the following conditions:
    +
    +      (a) You must give any other recipients of the Work or
    +          Derivative Works a copy of this License; and
    +
    +      (b) You must cause any modified files to carry prominent notices
    +          stating that You changed the files; and
    +
    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.
    +

    +   APPENDIX: How to apply the Apache License to your work.
    +
    +      To apply the Apache License to your work, attach the following
    +      boilerplate notice, with the fields enclosed by brackets "[]"

    +      Contribution(s) alone or by combination of their Contribution(s)

    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate
    +      as of the date such litigation is filed.
    +
    +   4. Redistribution. You may reproduce and distribute copies of the

    +          stating that You changed the files; and
    +
    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications
    +      represent, as a whole, an original work of authorship. For the purposes
    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +      Contribution(s) alone or by combination of their Contribution(s)

    +      institute patent litigation against any entity (including a
    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate
    +      as of the date such litigation is filed.
    +
    +   4. Redistribution. You may reproduce and distribute copies of the
    +      Work or Derivative Works thereof in any medium, with or without
    +      modifications, and in Source or Object form, provided that You

    +
    +      (a) You must give any other recipients of the Work or
    +          Derivative Works a copy of this License; and
    +
    +      (b) You must cause any modified files to carry prominent notices
    +          stating that You changed the files; and
    +
    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications
    +      represent, as a whole, an original work of authorship. For the purposes
    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including
    +      the original version of the Work and any modifications or additions

    +      means any form of electronic, verbal, or written communication sent

    +      (except as stated in this section) patent license to make, have made,
    +      use, offer to sell, sell, import, and otherwise transfer the Work,
    +      where such license applies only to those patent claims licensable
    +      by such Contributor that are necessarily infringed by their
    +      Contribution(s) alone or by combination of their Contribution(s)
    +      with the Work to which such Contribution(s) was submitted. If You
    +      institute patent litigation against any entity (including a
    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate
    +      as of the date such litigation is filed.
    +
    +   4. Redistribution. You may reproduce and distribute copies of the
    +      Work or Derivative Works thereof in any medium, with or without
    +      modifications, and in Source or Object form, provided that You

    +
    +      (a) You must give any other recipients of the Work or
    +          Derivative Works a copy of this License; and
    +
    +      (b) You must cause any modified files to carry prominent notices
    +          stating that You changed the files; and
    +
    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications

    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate

    +
    +   4. Redistribution. You may reproduce and distribute copies of the

    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor

    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications
    +      represent, as a whole, an original work of authorship. For the purposes
    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including
    +      the original version of the Work and any modifications or additions

    +      (except as stated in this section) patent license to make, have made,
    +      use, offer to sell, sell, import, and otherwise transfer the Work,
    +      where such license applies only to those patent claims licensable
    +      by such Contributor that are necessarily infringed by their
    +      Contribution(s) alone or by combination of their Contribution(s)
    +      with the Work to which such Contribution(s) was submitted. If You
    +      institute patent litigation against any entity (including a
    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate
    +      as of the date such litigation is filed.
    +
    +   4. Redistribution. You may reproduce and distribute copies of the
    +      Work or Derivative Works thereof in any medium, with or without

    +
    +      (a) You must give any other recipients of the Work or
    +          Derivative Works a copy of this License; and
    +
    +      (b) You must cause any modified files to carry prominent notices
    +          stating that You changed the files; and
    +
    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications
    +      represent, as a whole, an original work of authorship. For the purposes
    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate
    +      as of the date such litigation is filed.
    +
    +   4. Redistribution. You may reproduce and distribute copies of the

    +      (a) You must give any other recipients of the Work or
    +          Derivative Works a copy of this License; and
    +

    +
    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications
    +      represent, as a whole, an original work of authorship. For the purposes
    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate

    +
    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf

    +      incurred by, or claims asserted against, such Contributor by reason

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications

    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate

    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this

    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade

    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications

    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses

    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside

    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or

    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions

    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.

    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,

    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade

    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the

    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications

    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one

    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or

    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade

    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or

    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions

    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor

    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,

    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or

    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the

    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the

    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one

    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or

    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify

    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or

    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be

    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not

    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed

    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability
    +      incurred by, or claims asserted against, such Contributor by reason
    +      of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications

    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +      or a Contribution incorporated within the Work constitutes direct

    +      for use, reproduction, or distribution of Your modifications, or

    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of

    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents

    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +
    +   "Derivative Works" shall mean any work, whether in Source or Object
    +   form, that is based on (or derived from) the Work and for which the

    +
    +   "Derivative Works" shall mean any work, whether in Source or Object
    +   form, that is based on (or derived from) the Work and for which the
    +   editorial revisions, annotations, elaborations, or other modifications
    +   represent, as a whole, an original work of authorship. For the purposes
    +   of this License, Derivative Works shall not include works that remain

    +   by such Contributor that are necessarily infringed by their
    +   Contribution(s) alone or by combination of their Contribution(s)
    +   with the Work to which such Contribution(s) was submitted. If You
    +   institute patent litigation against any entity (including a
    +   cross-claim or counterclaim in a lawsuit) alleging that the Work
    +   or a Contribution incorporated within the Work constitutes direct
    +   or contributory patent infringement, then any patent licenses
    +   granted to You under this License for that Work shall terminate
    +   as of the date such litigation is filed.

    +4. Redistribution. You may reproduce and distribute copies of the

    +       excluding those notices that do not pertain to any part of
    +       the Derivative Works; and
    +
    +   (d) If the Work includes a "NOTICE" text file as part of its
    +       distribution, then any Derivative Works that You distribute must
    +       include a readable copy of the attribution notices contained
    +       within such NOTICE file, excluding those notices that do not
    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed
    +       as part of the Derivative Works; within the Source form or
    +       documentation, if provided along with the Derivative Works; or,

    +       wherever such third-party notices normally appear. The contents
    +       of the NOTICE file are for informational purposes only and

    +       notices within Derivative Works that You distribute, alongside
    +       or as an addendum to the NOTICE text from the Work, provided
    +       that such additional attribution notices cannot be construed
    +       as modifying the License.
    +
    +   You may add Your own copyright statement to Your modifications and
    +   may provide additional or different license terms and conditions

    +   reproduction, and distribution of the Work otherwise complies with
    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.
    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each
    +   Contributor provides its Contributions) on an "AS IS" BASIS,
    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions

    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any

    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.

    +
    +   "Object" form shall mean any form resulting from mechanical
    +   transformation or translation of a Source form, including but
    +   not limited to compiled object code, generated documentation,

    +
    +   "Work" shall mean the work of authorship, whether in Source or
    +   Object form, made available under the License, as indicated by a
    +   copyright notice that is included in or attached to the work

    +
    +   "Derivative Works" shall mean any work, whether in Source or Object
    +   form, that is based on (or derived from) the Work and for which the
    +   editorial revisions, annotations, elaborations, or other modifications
    +   represent, as a whole, an original work of authorship. For the purposes
    +   of this License, Derivative Works shall not include works that remain
    +   separable from, or merely link (or bind by name) to the interfaces of,
    +   the Work and Derivative Works thereof.
    +
    +   "Contribution" shall mean any work of authorship, including

    +   this License, each Contributor hereby grants to You a perpetual,

    +   copyright license to reproduce, prepare Derivative Works of,

    +
    +3. Grant of Patent License. Subject to the terms and conditions of
    +   this License, each Contributor hereby grants to You a perpetual,

    +   by such Contributor that are necessarily infringed by their
    +   Contribution(s) alone or by combination of their Contribution(s)
    +   with the Work to which such Contribution(s) was submitted. If You
    +   institute patent litigation against any entity (including a
    +   cross-claim or counterclaim in a lawsuit) alleging that the Work
    +   or a Contribution incorporated within the Work constitutes direct
    +   or contributory patent infringement, then any patent licenses
    +   granted to You under this License for that Work shall terminate
    +   as of the date such litigation is filed.
    +
    +4. Redistribution. You may reproduce and distribute copies of the
    +   Work or Derivative Works thereof in any medium, with or without
    +   modifications, and in Source or Object form, provided that You
    +   meet the following conditions:
    +
    +   (a) You must give any other recipients of the Work or

    +       stating that You changed the files; and
    +
    +   (c) You must retain, in the Source form of any Derivative Works
    +       that You distribute, all copyright, patent, trademark, and
    +       attribution notices from the Source form of the Work,
    +       excluding those notices that do not pertain to any part of
    +       the Derivative Works; and
    +
    +   (d) If the Work includes a "NOTICE" text file as part of its
    +       distribution, then any Derivative Works that You distribute must
    +       include a readable copy of the attribution notices contained
    +       within such NOTICE file, excluding those notices that do not
    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed
    +       as part of the Derivative Works; within the Source form or
    +       documentation, if provided along with the Derivative Works; or,
    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents
    +       of the NOTICE file are for informational purposes only and
    +       do not modify the License. You may add Your own attribution
    +       notices within Derivative Works that You distribute, alongside
    +       or as an addendum to the NOTICE text from the Work, provided
    +       that such additional attribution notices cannot be construed
    +       as modifying the License.
    +
    +   You may add Your own copyright statement to Your modifications and
    +   may provide additional or different license terms and conditions
    +   for use, reproduction, or distribution of Your modifications, or
    +   for any such Derivative Works as a whole, provided Your use,
    +   reproduction, and distribution of the Work otherwise complies with
    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.
    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each
    +   Contributor provides its Contributions) on an "AS IS" BASIS,
    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions
    +   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +
    +8. Limitation of Liability. In no event and under no legal theory,
    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +   form, that is based on (or derived from) the Work and for which the
    +   editorial revisions, annotations, elaborations, or other modifications

    +   subsequently incorporated within the Work.
    +
    +2. Grant of Copyright License. Subject to the terms and conditions of

    +
    +3. Grant of Patent License. Subject to the terms and conditions of

    +   by such Contributor that are necessarily infringed by their
    +   Contribution(s) alone or by combination of their Contribution(s)
    +   with the Work to which such Contribution(s) was submitted. If You

    +   cross-claim or counterclaim in a lawsuit) alleging that the Work
    +   or a Contribution incorporated within the Work constitutes direct
    +   or contributory patent infringement, then any patent licenses
    +   granted to You under this License for that Work shall terminate
    +   as of the date such litigation is filed.
    +
    +4. Redistribution. You may reproduce and distribute copies of the

    +   modifications, and in Source or Object form, provided that You
    +   meet the following conditions:

    +   (c) You must retain, in the Source form of any Derivative Works
    +       that You distribute, all copyright, patent, trademark, and
    +       attribution notices from the Source form of the Work,
    +       excluding those notices that do not pertain to any part of
    +       the Derivative Works; and
    +
    +   (d) If the Work includes a "NOTICE" text file as part of its
    +       distribution, then any Derivative Works that You distribute must
    +       include a readable copy of the attribution notices contained
    +       within such NOTICE file, excluding those notices that do not
    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed
    +       as part of the Derivative Works; within the Source form or
    +       documentation, if provided along with the Derivative Works; or,
    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents
    +       of the NOTICE file are for informational purposes only and
    +       do not modify the License. You may add Your own attribution
    +       notices within Derivative Works that You distribute, alongside
    +       or as an addendum to the NOTICE text from the Work, provided
    +       that such additional attribution notices cannot be construed
    +       as modifying the License.
    +
    +   You may add Your own copyright statement to Your modifications and
    +   may provide additional or different license terms and conditions
    +   for use, reproduction, or distribution of Your modifications, or
    +   for any such Derivative Works as a whole, provided Your use,
    +   reproduction, and distribution of the Work otherwise complies with
    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.
    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each
    +   Contributor provides its Contributions) on an "AS IS" BASIS,
    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions
    +   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +
    +8. Limitation of Liability. In no event and under no legal theory,
    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +       documentation, if provided along with the Derivative Works; or,
    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents

    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the

    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf

    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +
    +   "Derivative Works" shall mean any work, whether in Source or Object
    +   form, that is based on (or derived from) the Work and for which the
    +   editorial revisions, annotations, elaborations, or other modifications
    +   represent, as a whole, an original work of authorship. For the purposes
    +   of this License, Derivative Works shall not include works that remain

    +   cross-claim or counterclaim in a lawsuit) alleging that the Work
    +   or a Contribution incorporated within the Work constitutes direct
    +   or contributory patent infringement, then any patent licenses
    +   granted to You under this License for that Work shall terminate
    +   as of the date such litigation is filed.

    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed
    +       as part of the Derivative Works; within the Source form or

    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work

    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly

    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the

    +   Object form, made available under the License, as indicated by a

    +
    +   "Derivative Works" shall mean any work, whether in Source or Object
    +   form, that is based on (or derived from) the Work and for which the
    +   editorial revisions, annotations, elaborations, or other modifications
    +   represent, as a whole, an original work of authorship. For the purposes
    +   of this License, Derivative Works shall not include works that remain
    +   separable from, or merely link (or bind by name) to the interfaces of,
    +   the Work and Derivative Works thereof.

    +   by such Contributor that are necessarily infringed by their
    +   Contribution(s) alone or by combination of their Contribution(s)
    +   with the Work to which such Contribution(s) was submitted. If You
    +   institute patent litigation against any entity (including a
    +   cross-claim or counterclaim in a lawsuit) alleging that the Work
    +   or a Contribution incorporated within the Work constitutes direct
    +   or contributory patent infringement, then any patent licenses
    +   granted to You under this License for that Work shall terminate
    +   as of the date such litigation is filed.
    +
    +4. Redistribution. You may reproduce and distribute copies of the
    +   Work or Derivative Works thereof in any medium, with or without
    +   modifications, and in Source or Object form, provided that You
    +   meet the following conditions:
    +

    +   (c) You must retain, in the Source form of any Derivative Works
    +       that You distribute, all copyright, patent, trademark, and
    +       attribution notices from the Source form of the Work,
    +       excluding those notices that do not pertain to any part of
    +       the Derivative Works; and
    +
    +   (d) If the Work includes a "NOTICE" text file as part of its
    +       distribution, then any Derivative Works that You distribute must
    +       include a readable copy of the attribution notices contained
    +       within such NOTICE file, excluding those notices that do not
    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed
    +       as part of the Derivative Works; within the Source form or
    +       documentation, if provided along with the Derivative Works; or,
    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents
    +       of the NOTICE file are for informational purposes only and
    +       do not modify the License. You may add Your own attribution
    +       notices within Derivative Works that You distribute, alongside
    +       or as an addendum to the NOTICE text from the Work, provided
    +       that such additional attribution notices cannot be construed
    +       as modifying the License.
    +
    +   You may add Your own copyright statement to Your modifications and
    +   may provide additional or different license terms and conditions
    +   for use, reproduction, or distribution of Your modifications, or
    +   for any such Derivative Works as a whole, provided Your use,
    +   reproduction, and distribution of the Work otherwise complies with
    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.
    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each
    +   Contributor provides its Contributions) on an "AS IS" BASIS,
    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions
    +   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +
    +8. Limitation of Liability. In no event and under no legal theory,
    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +       pertain to any part of the Derivative Works, in at least one

    +       wherever such third-party notices normally appear. The contents

    +       notices within Derivative Works that You distribute, alongside
    +       or as an addendum to the NOTICE text from the Work, provided
    +       that such additional attribution notices cannot be construed

    +   reproduction, and distribution of the Work otherwise complies with
    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.
    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each
    +   Contributor provides its Contributions) on an "AS IS" BASIS,
    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions
    +   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +
    +8. Limitation of Liability. In no event and under no legal theory,
    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +   "Contributor" shall mean Licensor and any individual or Legal Entity
    +   on behalf of whom a Contribution has been received by Licensor and

    +   by such Contributor that are necessarily infringed by their
    +   Contribution(s) alone or by combination of their Contribution(s)
    +   with the Work to which such Contribution(s) was submitted. If You

    +   or a Contribution incorporated within the Work constitutes direct
    +   or contributory patent infringement, then any patent licenses
    +   granted to You under this License for that Work shall terminate
    +   as of the date such litigation is filed.
    +
    +4. Redistribution. You may reproduce and distribute copies of the

    +       attribution notices from the Source form of the Work,
    +       excluding those notices that do not pertain to any part of
    +       the Derivative Works; and
    +
    +   (d) If the Work includes a "NOTICE" text file as part of its
    +       distribution, then any Derivative Works that You distribute must
    +       include a readable copy of the attribution notices contained
    +       within such NOTICE file, excluding those notices that do not
    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed
    +       as part of the Derivative Works; within the Source form or
    +       documentation, if provided along with the Derivative Works; or,
    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents
    +       of the NOTICE file are for informational purposes only and
    +       do not modify the License. You may add Your own attribution
    +       notices within Derivative Works that You distribute, alongside
    +       or as an addendum to the NOTICE text from the Work, provided
    +       that such additional attribution notices cannot be construed
    +       as modifying the License.
    +
    +   You may add Your own copyright statement to Your modifications and
    +   may provide additional or different license terms and conditions
    +   for use, reproduction, or distribution of Your modifications, or
    +   for any such Derivative Works as a whole, provided Your use,
    +   reproduction, and distribution of the Work otherwise complies with
    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.
    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each
    +   Contributor provides its Contributions) on an "AS IS" BASIS,
    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions
    +   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +
    +8. Limitation of Liability. In no event and under no legal theory,
    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +       distribution, then any Derivative Works that You distribute must
    +       include a readable copy of the attribution notices contained
    +       within such NOTICE file, excluding those notices that do not
    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed

    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents
    +       of the NOTICE file are for informational purposes only and

    +       notices within Derivative Works that You distribute, alongside

    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.
    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each
    +   Contributor provides its Contributions) on an "AS IS" BASIS,
    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions
    +   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +
    +8. Limitation of Liability. In no event and under no legal theory,
    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +
    +      "Derivative Works" shall mean any work, whether in Source or Object
    +      form, that is based on (or derived from) the Work and for which the
    +      editorial revisions, annotations, elaborations, or other modifications
    +      represent, as a whole, an original work of authorship. For the purposes
    +      of this License, Derivative Works shall not include works that remain
    +      separable from, or merely link (or bind by name) to the interfaces of,
    +      the Work and Derivative Works thereof.
    +
    +      "Contribution" shall mean any work of authorship, including

    +      where such license applies only to those patent claims licensable
    +      by such Contributor that are necessarily infringed by their
    +      Contribution(s) alone or by combination of their Contribution(s)
    +      with the Work to which such Contribution(s) was submitted. If You
    +      institute patent litigation against any entity (including a
    +      cross-claim or counterclaim in a lawsuit) alleging that the Work
    +      or a Contribution incorporated within the Work constitutes direct
    +      or contributory patent infringement, then any patent licenses
    +      granted to You under this License for that Work shall terminate
    +      as of the date such litigation is filed.
    +
    +   4. Redistribution. You may reproduce and distribute copies of the

    +          stating that You changed the files; and
    +
    +      (c) You must retain, in the Source form of any Derivative Works
    +          that You distribute, all copyright, patent, trademark, and
    +          attribution notices from the Source form of the Work,
    +          excluding those notices that do not pertain to any part of
    +          the Derivative Works; and
    +
    +      (d) If the Work includes a "NOTICE" text file as part of its
    +          distribution, then any Derivative Works that You distribute must
    +          include a readable copy of the attribution notices contained
    +          within such NOTICE file, excluding those notices that do not
    +          pertain to any part of the Derivative Works, in at least one
    +          of the following places: within a NOTICE text file distributed
    +          as part of the Derivative Works; within the Source form or
    +          documentation, if provided along with the Derivative Works; or,
    +          within a display generated by the Derivative Works, if and
    +          wherever such third-party notices normally appear. The contents
    +          of the NOTICE file are for informational purposes only and
    +          do not modify the License. You may add Your own attribution
    +          notices within Derivative Works that You distribute, alongside
    +          or as an addendum to the NOTICE text from the Work, provided
    +          that such additional attribution notices cannot be construed
    +          as modifying the License.
    +
    +      You may add Your own copyright statement to Your modifications and
    +      may provide additional or different license terms and conditions
    +      for use, reproduction, or distribution of Your modifications, or
    +      for any such Derivative Works as a whole, provided Your use,
    +      reproduction, and distribution of the Work otherwise complies with
    +      the conditions stated in this License.
    +
    +   5. Submission of Contributions. Unless You explicitly state otherwise,
    +      any Contribution intentionally submitted for inclusion in the Work
    +      by You to the Licensor shall be under the terms and conditions of
    +      this License, without any additional terms or conditions.
    +      Notwithstanding the above, nothing herein shall supersede or modify
    +      the terms of any separate license agreement you may have executed
    +      with Licensor regarding such Contributions.
    +
    +   6. Trademarks. This License does not grant permission to use the trade
    +      names, trademarks, service marks, or product names of the Licensor,
    +      except as required for reasonable and customary use in describing the
    +      origin of the Work and reproducing the content of the NOTICE file.
    +
    +   7. Disclaimer of Warranty. Unless required by applicable law or
    +      agreed to in writing, Licensor provides the Work (and each
    +      Contributor provides its Contributions) on an "AS IS" BASIS,
    +      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +      implied, including, without limitation, any warranties or conditions
    +      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +      PARTICULAR PURPOSE. You are solely responsible for determining the
    +      appropriateness of using or redistributing the Work and assume any
    +      risks associated with Your exercise of permissions under this License.
    +
    +   8. Limitation of Liability. In no event and under no legal theory,
    +      whether in tort (including negligence), contract, or otherwise,
    +      unless required by applicable law (such as deliberate and grossly
    +      negligent acts) or agreed to in writing, shall any Contributor be
    +      liable to You for damages, including any direct, indirect, special,
    +      incidental, or consequential damages of any character arising as a
    +      result of this License or out of the use or inability to use the
    +      Work (including but not limited to damages for loss of goodwill,
    +      work stoppage, computer failure or malfunction, or any and all
    +      other commercial damages or losses), even if such Contributor
    +      has been advised of the possibility of such damages.
    +
    +   9. Accepting Warranty or Additional Liability. While redistributing
    +      the Work or Derivative Works thereof, You may choose to offer,
    +      and charge a fee for, acceptance of support, warranty, indemnity,
    +      or other liability obligations and/or rights consistent with this
    +      License. However, in accepting such obligations, You may act only
    +      on Your own behalf and on Your sole responsibility, not on behalf
    +      of any other Contributor, and only if You agree to indemnify,
    +      defend, and hold each Contributor harmless for any liability

    +   Work (including but not limited to damages for loss of goodwill,

    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +
    +   "Source" form shall mean the preferred form for making modifications,

    +   source, and configuration files.
    +
    +   "Object" form shall mean any form resulting from mechanical
    +   transformation or translation of a Source form, including but
    +   not limited to compiled object code, generated documentation,
    +   and conversions to other media types.
    +
    +   "Work" shall mean the work of authorship, whether in Source or
    +   Object form, made available under the License, as indicated by a
    +   copyright notice that is included in or attached to the work
    +   (an example is provided in the Appendix below).
    +
    +   "Derivative Works" shall mean any work, whether in Source or Object
    +   form, that is based on (or derived from) the Work and for which the
    +   editorial revisions, annotations, elaborations, or other modifications
    +   represent, as a whole, an original work of authorship. For the purposes
    +   of this License, Derivative Works shall not include works that remain
    +   separable from, or merely link (or bind by name) to the interfaces of,
    +   the Work and Derivative Works thereof.
    +
    +   "Contribution" shall mean any work of authorship, including
    +   the original version of the Work and any modifications or additions
    +   to that Work or Derivative Works thereof, that is intentionally
    +   submitted to Licensor for inclusion in the Work by the copyright owner
    +   or by an individual or Legal Entity authorized to submit on behalf of
    +   the copyright owner. For the purposes of this definition, "submitted"
    +   means any form of electronic, verbal, or written communication sent
    +   to the Licensor or its representatives, including but not limited to
    +   communication on electronic mailing lists, source code control systems,
    +   and issue tracking systems that are managed by, or on behalf of, the
    +   Licensor for the purpose of discussing and improving the Work, but
    +   excluding communication that is conspicuously marked or otherwise
    +   designated in writing by the copyright owner as "Not a Contribution."
    +
    +   "Contributor" shall mean Licensor and any individual or Legal Entity
    +   on behalf of whom a Contribution has been received by Licensor and
    +   subsequently incorporated within the Work.
    +
    +2. Grant of Copyright License. Subject to the terms and conditions of
    +   this License, each Contributor hereby grants to You a perpetual,
    +   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
    +   copyright license to reproduce, prepare Derivative Works of,
    +   publicly display, publicly perform, sublicense, and distribute the
    +   Work and such Derivative Works in Source or Object form.
    +
    +3. Grant of Patent License. Subject to the terms and conditions of
    +   this License, each Contributor hereby grants to You a perpetual,
    +   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
    +   (except as stated in this section) patent license to make, have made,
    +   use, offer to sell, sell, import, and otherwise transfer the Work,
    +   where such license applies only to those patent claims licensable
    +   by such Contributor that are necessarily infringed by their
    +   Contribution(s) alone or by combination of their Contribution(s)
    +   with the Work to which such Contribution(s) was submitted. If You
    +   institute patent litigation against any entity (including a
    +   cross-claim or counterclaim in a lawsuit) alleging that the Work
    +   or a Contribution incorporated within the Work constitutes direct
    +   or contributory patent infringement, then any patent licenses
    +   granted to You under this License for that Work shall terminate
    +   as of the date such litigation is filed.
    +
    +4. Redistribution. You may reproduce and distribute copies of the
    +   Work or Derivative Works thereof in any medium, with or without
    +   modifications, and in Source or Object form, provided that You
    +   meet the following conditions:
    +
    +   (a) You must give any other recipients of the Work or
    +       Derivative Works a copy of this License; and
    +
    +   (b) You must cause any modified files to carry prominent notices
    +       stating that You changed the files; and
    +
    +   (c) You must retain, in the Source form of any Derivative Works
    +       that You distribute, all copyright, patent, trademark, and
    +       attribution notices from the Source form of the Work,
    +       excluding those notices that do not pertain to any part of
    +       the Derivative Works; and
    +
    +   (d) If the Work includes a "NOTICE" text file as part of its
    +       distribution, then any Derivative Works that You distribute must
    +       include a readable copy of the attribution notices contained
    +       within such NOTICE file, excluding those notices that do not
    +       pertain to any part of the Derivative Works, in at least one
    +       of the following places: within a NOTICE text file distributed
    +       as part of the Derivative Works; within the Source form or
    +       documentation, if provided along with the Derivative Works; or,
    +       within a display generated by the Derivative Works, if and
    +       wherever such third-party notices normally appear. The contents
    +       of the NOTICE file are for informational purposes only and
    +       do not modify the License. You may add Your own attribution
    +       notices within Derivative Works that You distribute, alongside
    +       or as an addendum to the NOTICE text from the Work, provided
    +       that such additional attribution notices cannot be construed
    +       as modifying the License.
    +
    +   You may add Your own copyright statement to Your modifications and
    +   may provide additional or different license terms and conditions
    +   for use, reproduction, or distribution of Your modifications, or
    +   for any such Derivative Works as a whole, provided Your use,
    +   reproduction, and distribution of the Work otherwise complies with
    +   the conditions stated in this License.
    +
    +5. Submission of Contributions. Unless You explicitly state otherwise,
    +   any Contribution intentionally submitted for inclusion in the Work
    +   by You to the Licensor shall be under the terms and conditions of
    +   this License, without any additional terms or conditions.
    +   Notwithstanding the above, nothing herein shall supersede or modify
    +   the terms of any separate license agreement you may have executed
    +   with Licensor regarding such Contributions.
    +
    +6. Trademarks. This License does not grant permission to use the trade
    +   names, trademarks, service marks, or product names of the Licensor,
    +   except as required for reasonable and customary use in describing the
    +   origin of the Work and reproducing the content of the NOTICE file.
    +
    +7. Disclaimer of Warranty. Unless required by applicable law or
    +   agreed to in writing, Licensor provides the Work (and each
    +   Contributor provides its Contributions) on an "AS IS" BASIS,
    +   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    +   implied, including, without limitation, any warranties or conditions
    +   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    +   PARTICULAR PURPOSE. You are solely responsible for determining the
    +   appropriateness of using or redistributing the Work and assume any
    +   risks associated with Your exercise of permissions under this License.
    +
    +8. Limitation of Liability. In no event and under no legal theory,
    +   whether in tort (including negligence), contract, or otherwise,
    +   unless required by applicable law (such as deliberate and grossly
    +   negligent acts) or agreed to in writing, shall any Contributor be
    +   liable to You for damages, including any direct, indirect, special,
    +   incidental, or consequential damages of any character arising as a
    +   result of this License or out of the use or inability to use the
    +   Work (including but not limited to damages for loss of goodwill,
    +   work stoppage, computer failure or malfunction, or any and all
    +   other commercial damages or losses), even if such Contributor
    +   has been advised of the possibility of such damages.
    +
    +9. Accepting Warranty or Additional Liability. While redistributing
    +   the Work or Derivative Works thereof, You may choose to offer,
    +   and charge a fee for, acceptance of support, warranty, indemnity,
    +   or other liability obligations and/or rights consistent with this
    +   License. However, in accepting such obligations, You may act only
    +   on Your own behalf and on Your sole responsibility, not on behalf
    +   of any other Contributor, and only if You agree to indemnify,
    +   defend, and hold each Contributor harmless for any liability
    +   incurred by, or claims asserted against, such Contributor by reason
    +   of your accepting any such warranty or additional liability.

    +
    +CC0 1.0 Universal
    +
    +    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
    +    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
    +    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
    +    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
    +    REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
    +    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
    +    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
    +    HEREUNDER.
    +
    +Statement of Purpose
    +
    +The laws of most jurisdictions throughout the world automatically confer
    +exclusive Copyright and Related Rights (defined below) upon the creator
    +and subsequent owner(s) (each and all, an "owner") of an original work of
    +authorship and/or a database (each, a "Work").
    +
    +Certain owners wish to permanently relinquish those rights to a Work for
    +the purpose of contributing to a commons of creative, cultural and
    +scientific works ("Commons") that the public can reliably and without fear
    +of later claims of infringement build upon, modify, incorporate in other
    +works, reuse and redistribute as freely as possible in any form whatsoever
    +and for any purposes, including without limitation commercial purposes.
    +These owners may contribute to the Commons to promote the ideal of a free
    +culture and the further production of creative, cultural and scientific
    +works, or to gain reputation or greater distribution for their Work in
    +part through the use and efforts of others.
    +
    +For these and/or other purposes and motivations, and without any
    +expectation of additional consideration or compensation, the person
    +associating CC0 with a Work (the "Affirmer"), to the extent that he or she
    +is an owner of Copyright and Related Rights in the Work, voluntarily
    +elects to apply CC0 to the Work and publicly distribute the Work under its
    +terms, with knowledge of his or her Copyright and Related Rights in the
    +Work and the meaning and intended legal effect of CC0 on those rights.
    +
    +1. Copyright and Related Rights. A Work made available under CC0 may be
    +protected by copyright and related or neighboring rights ("Copyright and
    +Related Rights"). Copyright and Related Rights include, but are not
    +limited to, the following:
    +
    +  i. the right to reproduce, adapt, distribute, perform, display,
    +     communicate, and translate a Work;
    + ii. moral rights retained by the original author(s) and/or performer(s);
    +iii. publicity and privacy rights pertaining to a person's image or
    +     likeness depicted in a Work;
    + iv. rights protecting against unfair competition in regards to a Work,
    +     subject to the limitations in paragraph 4(a), below;
    +  v. rights protecting the extraction, dissemination, use and reuse of data
    +     in a Work;
    + vi. database rights (such as those arising under Directive 96/9/EC of the
    +     European Parliament and of the Council of 11 March 1996 on the legal
    +     protection of databases, and under any national implementation
    +     thereof, including any amended or successor version of such
    +     directive); and
    +vii. other similar, equivalent or corresponding rights throughout the
    +     world based on applicable law or treaty, and any national
    +     implementations thereof.
    +
    +2. Waiver. To the greatest extent permitted by, but not in contravention
    +of, applicable law, Affirmer hereby overtly, fully, permanently,
    +irrevocably and unconditionally waives, abandons, and surrenders all of
    +Affirmer's Copyright and Related Rights and associated claims and causes
    +of action, whether now known or unknown (including existing as well as
    +future claims and causes of action), in the Work (i) in all territories
    +worldwide, (ii) for the maximum duration provided by applicable law or
    +treaty (including future time extensions), (iii) in any current or future
    +medium and for any number of copies, and (iv) for any purpose whatsoever,
    +including without limitation commercial, advertising or promotional
    +purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
    +member of the public at large and to the detriment of Affirmer's heirs and
    +successors, fully intending that such Waiver shall not be subject to
    +revocation, rescission, cancellation, termination, or any other legal or
    +equitable action to disrupt the quiet enjoyment of the Work by the public
    +as contemplated by Affirmer's express Statement of Purpose.
    +
    +3. Public License Fallback. Should any part of the Waiver for any reason
    +be judged legally invalid or ineffective under applicable law, then the
    +Waiver shall be preserved to the maximum extent permitted taking into
    +account Affirmer's express Statement of Purpose. In addition, to the
    +extent the Waiver is so judged Affirmer hereby grants to each affected
    +person a royalty-free, non transferable, non sublicensable, non exclusive,
    +irrevocable and unconditional license to exercise Affirmer's Copyright and
    +Related Rights in the Work (i) in all territories worldwide, (ii) for the
    +maximum duration provided by applicable law or treaty (including future
    +time extensions), (iii) in any current or future medium and for any number
    +of copies, and (iv) for any purpose whatsoever, including without
    +limitation commercial, advertising or promotional purposes (the
    +"License"). The License shall be deemed effective as of the date CC0 was
    +applied by Affirmer to the Work. Should any part of the License for any
    +reason be judged legally invalid or ineffective under applicable law, such
    +partial invalidity or ineffectiveness shall not invalidate the remainder
    +of the License, and in such case Affirmer hereby affirms that he or she
    +will not (i) exercise any of his or her remaining Copyright and Related
    +Rights in the Work or (ii) assert any associated claims and causes of
    +action with respect to the Work, in either case contrary to Affirmer's
    +express Statement of Purpose.
    +
    +4. Limitations and Disclaimers.
    +
    + a. No trademark or patent rights held by Affirmer are waived, abandoned,
    +    surrendered, licensed or otherwise affected by this document.
    + b. Affirmer offers the Work as-is and makes no representations or
    +    warranties of any kind concerning the Work, express, implied,
    +    statutory or otherwise, including without limitation warranties of
    +    title, merchantability, fitness for a particular purpose, non
    +    infringement, or the absence of latent or other defects, accuracy, or
    +    the present or absence of errors, whether or not discoverable, all to
    +    the greatest extent permissible under applicable law.
    + c. Affirmer disclaims responsibility for clearing rights of other persons
    +    that may apply to the Work or any use thereof, including without
    +    limitation any person's Copyright and Related Rights in the Work.
    +    Further, Affirmer disclaims responsibility for obtaining any necessary
    +    consents, permissions or other rights required for any use of the
    +    Work.
    + d. Affirmer understands and acknowledges that Creative Commons is not a
    +    party to this document and has no duty or obligation with respect to
    +    this CC0 or use of the Work.

    +2. License Grants and Conditions
    +--------------------------------
    +
    +2.1. Grants
    +
    +Each Contributor hereby grants You a world-wide, royalty-free,
    +non-exclusive license:
    +
    +(a) under intellectual property rights (other than patent or trademark)
    +    Licensable by such Contributor to use, reproduce, make available,
    +    modify, display, perform, distribute, and otherwise exploit its
    +    Contributions, either on an unmodified basis, with Modifications, or
    +    as part of a Larger Work; and
    +
    +(b) under Patent Claims of such Contributor to make, use, sell, offer
    +    for sale, have made, import, and otherwise transfer either its
    +    Contributions or its Contributor Version.
    +
    +2.2. Effective Date
    +
    +The licenses granted in Section 2.1 with respect to any Contribution
    +become effective for each Contribution on the date the Contributor first
    +distributes such Contribution.
    +
    +2.3. Limitations on Grant Scope
    +
    +The licenses granted in this Section 2 are the only rights granted under
    +this License. No additional rights or licenses will be implied from the
    +distribution or licensing of Covered Software under this License.
    +Notwithstanding Section 2.1(b) above, no patent license is granted by a
    +Contributor:
    +
    +(a) for any code that a Contributor has removed from Covered Software;
    +    or
    +
    +(b) for infringements caused by: (i) Your and any other third party's
    +    modifications of Covered Software, or (ii) the combination of its
    +    Contributions with other software (except as part of its Contributor
    +    Version); or
    +
    +(c) under Patent Claims infringed by Covered Software in the absence of
    +    its Contributions.
    +
    +This License does not grant any rights in the trademarks, service marks,
    +or logos of any Contributor (except as may be necessary to comply with
    +the notice requirements in Section 3.4).
    +
    +2.4. Subsequent Licenses
    +
    +No Contributor makes additional grants as a result of Your choice to
    +distribute the Covered Software under a subsequent version of this
    +License (see Section 10.2) or under the terms of a Secondary License (if
    +permitted under the terms of Section 3.3).
    +
    +2.5. Representation
    +
    +Each Contributor represents that the Contributor believes its
    +Contributions are its original creation(s) or it has sufficient rights
    +to grant the rights to its Contributions conveyed by this License.
    +
    +2.6. Fair Use
    +
    +This License is not intended to limit any rights You have under
    +applicable copyright doctrines of fair use, fair dealing, or other
    +equivalents.
    +
    +2.7. Conditions
    +
    +Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
    +in Section 2.1.
    +
    +3. Responsibilities
    +-------------------
    +
    +3.1. Distribution of Source Form
    +
    +All distribution of Covered Software in Source Code Form, including any
    +Modifications that You create or to which You contribute, must be under
    +the terms of this License. You must inform recipients that the Source
    +Code Form of the Covered Software is governed by the terms of this
    +License, and how they can obtain a copy of this License. You may not
    +attempt to alter or restrict the recipients' rights in the Source Code
    +Form.
    +
    +3.2. Distribution of Executable Form
    +
    +If You distribute Covered Software in Executable Form then:
    +
    +(a) such Covered Software must also be made available in Source Code
    +    Form, as described in Section 3.1, and You must inform recipients of
    +    the Executable Form how they can obtain a copy of such Source Code
    +    Form by reasonable means in a timely manner, at a charge no more
    +    than the cost of distribution to the recipient; and
    +
    +(b) You may distribute such Executable Form under the terms of this
    +    License, or sublicense it under different terms, provided that the
    +    license for the Executable Form does not attempt to limit or alter
    +    the recipients' rights in the Source Code Form under this License.
    +
    +3.3. Distribution of a Larger Work
    +
    +You may create and distribute a Larger Work under terms of Your choice,
    +provided that You also comply with the requirements of this License for
    +the Covered Software. If the Larger Work is a combination of Covered
    +Software with a work governed by one or more Secondary Licenses, and the
    +Covered Software is not Incompatible With Secondary Licenses, this
    +License permits You to additionally distribute such Covered Software
    +under the terms of such Secondary License(s), so that the recipient of
    +the Larger Work may, at their option, further distribute the Covered
    +Software under the terms of either this License or such Secondary
    +License(s).
    +
    +3.4. Notices
    +
    +You may not remove or alter the substance of any license notices
    +(including copyright notices, patent notices, disclaimers of warranty,
    +or limitations of liability) contained within the Source Code Form of
    +the Covered Software, except that You may alter any license notices to
    +the extent required to remedy known factual inaccuracies.
    +
    +3.5. Application of Additional Terms
    +
    +You may choose to offer, and to charge a fee for, warranty, support,
    +indemnity or liability obligations to one or more recipients of Covered
    +Software. However, You may do so only on Your own behalf, and not on
    +behalf of any Contributor. You must make it absolutely clear that any
    +such warranty, support, indemnity, or liability obligation is offered by
    +You alone, and You hereby agree to indemnify every Contributor for any
    +liability incurred by such Contributor as a result of warranty, support,
    +indemnity or liability terms You offer. You may include additional
    +disclaimers of warranty and limitations of liability specific to any
    +jurisdiction.
    +
    +4. Inability to Comply Due to Statute or Regulation
    +---------------------------------------------------
    +
    +If it is impossible for You to comply with any of the terms of this
    +License with respect to some or all of the Covered Software due to
    +statute, judicial order, or regulation then You must: (a) comply with
    +the terms of this License to the maximum extent possible; and (b)
    +describe the limitations and the code they affect. Such description must
    +be placed in a text file included with all distributions of the Covered
    +Software under this License. Except to the extent prohibited by statute
    +or regulation, such description must be sufficiently detailed for a
    +recipient of ordinary skill to be able to understand it.
    +
    +5. Termination
    +--------------
    +
    +5.1. The rights granted under this License will terminate automatically
    +if You fail to comply with any of its terms. However, if You become
    +compliant, then the rights granted under this License from a particular
    +Contributor are reinstated (a) provisionally, unless and until such
    +Contributor explicitly and finally terminates Your grants, and (b) on an
    +ongoing basis, if such Contributor fails to notify You of the
    +non-compliance by some reasonable means prior to 60 days after You have
    +come back into compliance. Moreover, Your grants from a particular
    +Contributor are reinstated on an ongoing basis if such Contributor
    +notifies You of the non-compliance by some reasonable means, this is the
    +first time You have received notice of non-compliance with this License
    +from such Contributor, and You become compliant prior to 30 days after
    +Your receipt of the notice.
    +
    +5.2. If You initiate litigation against any entity by asserting a patent
    +infringement claim (excluding declaratory judgment actions,
    +counter-claims, and cross-claims) alleging that a Contributor Version
    +directly or indirectly infringes any patent, then the rights granted to
    +You by any and all Contributors for the Covered Software under Section
    +2.1 of this License shall terminate.
    +
    +5.3. In the event of termination under Sections 5.1 or 5.2 above, all
    +end user license agreements (excluding distributors and resellers) which
    +have been validly granted by You or Your distributors under this License
    +prior to termination shall survive termination.

    +----------------
    +
    +This License represents the complete agreement concerning the subject
    +matter hereof. If any provision of this License is held to be
    +unenforceable, such provision shall be reformed only to the extent
    +necessary to make it enforceable. Any law or regulation which provides
    +that the language of a contract shall be construed against the drafter
    +shall not be used to construe this License against a Contributor.

    +steward.
    +
    +10.3. Modified Versions
    +
    +If you create software not governed by this License, and you want to
    +create a new license for such software, you may create and use a
    +modified version of this License if you rename the license and remove
    +any references to the name of the license steward (except to note that
    +such modified license differs from this License).
    +
    +10.4. Distributing Source Code Form that is Incompatible With Secondary
    +Licenses

Boundary tests cover 0, 1, 39, 40, 41, 80, and 81 candidates, including +a partially filled last batch.

Candidate IDs, +probabilities, resolved models, and request counts were checked for every record. +All three 80-candidate queries made exactly two batched calls. Live vector, FTS, +hybrid, empty-FTS, and multivector integration checks also passed in both modes. +No correctness fixes were needed. + +The subsequent batch-ordering simplification passed all 124 automated tests and +a fresh four-query live check (original query indices 0, 1, 2, and 8; 292 candidate +pairs). Unbatched/batched calls were 292/8, including exactly two calls for the +80-candidate case.

The full run +was manually stopped after 494 matched queries; this summary uses the first 100 +input queries without selection by latency or scores. Counts above exclude other +queries completed before stopping. The high unbatched p95 is retained as observed; +it is not attributed to a specific cause. A complete 2,000-query paired benchmark +is still needed before making a general performance or quality claim. Exact values +and configuration are in [the subset test report](typesafe_subset_test.json). + +The historical GooAQ results motivated this patch: the earlier custom adapter +reported 186 ms median / 387 ms p95; native unbatched scoring at concurrency 32 +reported 805 ms / 1,193 ms for 2,000 queries and 136,586 candidate pairs using +`jev-1.13.0`. Those separate runs are not measurements of this patch. See the +[research results](https://github.com/lancedb/research/blob/codex/use-native-typesafe-reranker/reranking/results/README.md) +and [earlier adapter](https://github.com/lancedb/research/blob/412a522/reranking/jev_reranker.py). + +## Run the paired benchmark + +Use the exact `candidates.json` from the research benchmark cache. It is a JSON +array of records with `query`, expected `answer`, ordered `vector` and `fts` ID +lists, and a `documents` mapping from string IDs to text. Distinct IDs may have +identical text. To prepare candidates without scoring models, use the research +branch's [benchmark](https://github.com/lancedb/research/blob/codex/use-native-typesafe-reranker/reranking/compare_jev.py) +with `--models none`; its default corpus and query counts reproduce the protocol. + +After bootstrapping this checkout's Python development environment, run from +`python/` (set `TYPESAFE_API_KEY` or pass `--api-key-file`): + +```sh +uv run --extra tests --with typesafe-sdk==0.7.1 benchmarks/bench_typesafe.py \ + --candidates /path/to/research/reranking/.benchmark-cache/candidates.json \ + --model jev-1.13.0 --max-concurrency 32 \ + --cache /tmp/typesafe-batching-fresh \ + --output /tmp/typesafe-batching-results.json +``` + +Both modes use the same installed SDK, model, prompt, candidates, and concurrency. +They score each query's candidate union once, alternating which mode runs first. +Timings include native reranking and SDK retries, exclude retrieval, and report +median/p95 milliseconds.

The output includes resolved model IDs, package +versions, implementation and candidate hashes, and vector/FTS/hybrid Hit@5 and +Hit@10.

For example, + ``split_strategy=lambda b: b.bootstrap_sample(10_000, fixed=num_splits, + seed=42)`` draws 10,000 samples with replacement, divided evenly across + ``num_splits`` splits. + shuffle_seed: + Base seed for the random permutation.

Larger values amortise per-request overhead (critical on object + storage) at the cost of higher memory usage per split buffer. Defaults + to ``DEFAULT_READ_BATCH_SIZE`` (64). + io_queue_depth: + Number of fetched batches to keep ahead of the transform stage per + split: this bounds the combined count of in-flight fetches and + already-fetched batches still waiting for a transform slot. Higher + values overlap storage latency with transform and training compute + at the cost of more memory and threads, but I/O stops running ahead + once this many batches are buffered, applying backpressure when the + transform stage (or ``transform_queue_depth``) is the bottleneck. + Must be greater than zero. Defaults to ``DEFAULT_PREFETCH_BATCHES`` + (4). + columns: + Optional list of column names to read. When set, only those columns + are fetched from storage; all others are omitted. ``None`` (the + default) reads every column. + shuffle_clump_size: + When set, rows are shuffled in contiguous groups of this size rather + than individually. Larger clumps improve I/O locality (important on + object storage) at the cost of reduced randomness. ``None`` (the + default) shuffles rows individually. + filter: + Optional SQL filter expression (e.g. ``"label = 'dog'"``). Only rows + that satisfy the predicate are included in the permutation. The filter + is applied during permutation construction so split sizes reflect the + filtered row count. + transform: + Optional callable applied to each ``pyarrow.RecordBatch`` before rows + are yielded. Receives one batch at a time and must return an iterable + whose length equals the number of rows in the batch. When ``None`` + (the default) rows are returned as plain Python dicts. + transform_parallelism: + Maximum number of transforms to run concurrently. Must be greater + than zero. When ``None`` (the default), uses ``os.cpu_count()`` or 1 + when the CPU count is unavailable. + pack_sequences: + Sequence-packing mode: token lists from consecutive documents are + joined with ``eos_id`` and sliced into blocks of this many tokens. + Each item is then a dict of two ``(pack_sequences,)`` LongTensors — + ``input_ids`` and ``doc_ids`` (per-position document index within + the block, for block-diagonal masks or position-id resets). + * Packing happens independently per owned split and preserves per-split + resume state. + * When a split cannot fill a real block for a cycle but an owned sibling + still can, or when only a short tail remains at epoch end, the short buffer + is padded to ``pack_sequences`` with ``pad_id`` so every local cycle emits + one block per owned split. + * ``eos_id``, ``pad_id``, and ``columns`` naming a single integer-list + column are required; incompatible with ``transform``. + eos_id: + Separator token id between packed documents. Required with + ``pack_sequences``, ignored otherwise. + pad_id: + Padding token id used to complete blocks when a split runs out of + real tokens mid-cycle or at epoch end. Required with + ``pack_sequences``, ignored otherwise. It must be reserved for padding: + padding positions retain the preceding document's ``doc_id`` (or zero + in an all-padding block), so callers must mask them separately using + ``input_ids == pad_id``. + blocks_per_epoch: + Total number of packed blocks emitted globally per epoch. Required with + ``pack_sequences``. An integer must be divisible by ``num_splits``. + Every logical split emits exactly ``blocks_per_epoch / num_splits`` + blocks: exhausted splits emit padding, while tokens beyond the budget + are left out of the epoch. This fixed per-split budget keeps packed + iteration and checkpoints independent of rank topology. + Pass ``"auto"`` to estimate a corpus-level budget from a bounded sample + of token lists. The estimate may be inaccurate. + on_transform_error: + What to do when the transform raises an exception: + + - ``"raise"`` (the default): the exception propagates and iteration + aborts. + - ``"skip"``: the failing rows are dropped and iteration continues. + - ``"warn"``: like ``"skip"``, but a warning is logged for each + failing batch. + - a callable ``handler(exc) -> bool``: called with the exception; + return ``True`` to skip the failing rows or ``False`` to re-raise. + Useful to skip only expected error types (compatible with + ``webdataset.handlers`` style handlers). + + When a batch fails, the transform is re-invoked on each single-row + slice of the batch so that only the rows that actually fail are + dropped. Transforms should therefore be deterministic and accept + batches of any size (including one row). Skipped rows are counted in + ``rows_skipped``. + + Skipping weakens the elastic-determinism guarantee at the end of the + epoch: splits that lose more rows than others run dry earlier, and + each rank's iterator ends at the last cycle where every split *it + owns* still has a row. Because bad rows are not distributed evenly + across splits, this means one rank's iterator can yield noticeably + fewer or more steps than another rank's *in the same run* — there is + no cross-rank coordination that stops every rank at the same global + step. This is generally safe for asynchronous or single-rank use, + but synchronous distributed training (e.g. ranks that call + ``all_reduce`` every step) can hang or deadlock if one rank's + iterator is exhausted while others are still stepping; callers doing + synchronous multi-rank training with ``on_transform_error != "raise"`` + are responsible for their own cross-rank stopping mechanism (e.g. + broadcasting a stop signal on ``StopIteration``). The final few + global steps can also differ across topologies (bounded by the skew + in bad-row counts across splits). The sequence of samples yielded + from each split remains deterministic. Mid-epoch + checkpoints remain exact provided the transform fails + deterministically; in multi-rank training each rank must save its + own ``state_dict`` and the states must be combined with + ``merge_state_dicts`` before resuming on a different topology. + Prefer the ``filter`` parameter when bad rows can be expressed as a + SQL predicate (e.g. ``"col IS NOT NULL"``) — filtering happens before + splits are built, so every guarantee is fully preserved. + transform_queue_depth: + Number of transform-result batches to buffer per split in the + post-transform queue before backpressure is applied to the transform + stage. When the combined count of in-flight transform futures and + already-buffered rows for a split reaches + ``transform_queue_depth * read_batch_size``, no new transforms are + submitted for that split until the consumer catches up. Useful for + capping peak memory when the consumer (e.g. a GPU training step) is + slower than the transform stage. Must be greater than zero. + ``None`` (the default) imposes no limit. + worker_info_override: + If set, used in place of ``torch.utils.data.get_worker_info()`` to + determine the DataLoader worker assignment.

A pull-based adapter over the [`metrics`] crate facade. +//! +//! LanceDB (through Lance core) publishes metrics — currently object store +//! request counts, bytes, latency, errors, and throttles — through the global +//! [`metrics`] facade without choosing a backend. This module installs a +//! process-global [`metrics::Recorder`] that aggregates those metrics into +//! lock-free cumulative storage and exposes that state as a snapshot, so callers +//! can feed it into a pull-based exporter such as OpenTelemetry. +//! +//! The language bindings build their OpenTelemetry integrations on top of the +//! three public entry points here: [`register_metrics_recorder`], +//! [`metrics_catalog`], and [`snapshot_metrics`]. +//! +//! The recorder is *generic*: it records any metric emitted through the facade, +//! keyed by name and labels. Object store metrics are the first producer, but +//! nothing here is specific to them. New metrics flow through automatically; +//! they only need to be described (via the `metrics` `describe_*!` macros) so +//! callers can discover their name, kind, and unit up front. +//! +//! ## Why pull, not push +//! +//! OpenTelemetry collects on its own schedule and invokes observable-instrument +//! callbacks at collection time. Cumulative counters map directly onto OTel's +//! `ObservableCounter` semantics. So the adapter aggregates in Rust and lets the +//! collection thread pull a [`snapshot`](snapshot_metrics) on demand. +//! +//! ## Histograms +//! +//! OpenTelemetry has no asynchronous histogram instrument, so histograms cannot +//! be pulled as-is. Instead each histogram is aggregated into fixed buckets +//! (Prometheus style) and exposed as cumulative `le` bucket counts plus a count +//! and sum, which the caller can surface as observable counters. + +use std::collections::HashMap; +use std::sync::atomic::{AtomicU64, Ordering}; +use std::sync::{Arc, LazyLock, Mutex, OnceLock, RwLock}; + +use metrics::{Counter, Gauge, Histogram, Key, KeyName, Metadata, Recorder, SharedString, Unit}; +use metrics_util::registry::{Registry, Storage}; + +/// Bucket boundaries used when a histogram has no registered bounds.

Security properties: +//! +//! - Opt-in only; callers that do not configure a cache stay memory-only. +//! - Only refresh tokens are persisted. Access tokens never touch disk, so +//! there are no local expiry decisions to get wrong when clocks move. +//! - No client secret is ever stored. +//! - The cache directory is private (`0700`) and each record is `0600`, +//! owner-checked, and symlink-rejected on Unix; records are replaced +//! atomically via `rename` so a crash can never leave a torn file. +//! - Cache filenames are SHA-256 hashes of the canonical issuer, client, +//! scope, resource, audience, flow, and client-auth identity. No secret appears +//! in a filename. +//! - Refresh-token rotation is serialized across processes with a per-key +//! advisory file lock (`flock` on Unix, `LockFileEx` on Windows).
