fix(python): preserve request metadata for missing remote tables
Fixes #4750 Remote missing-table errors retained HTTP metadata in Rust but the Python binding converted them to a plain `ValueError`, discarding the request ID and status. This raises a `TableNotFoundError` that preserves the original message, request ID, status code, and chained HTTP cause while remaining compatible with existing `ValueError` and `lance_namespace.errors.TableNotFoundError` handlers. Local and non-HTTP errors retain their previous behavior. Validation covers sync and async opens across cached/uncached and root/nested paths, exception pickling, local compatibility, the remote and error test suites, Clippy, formatting, Ruff, and all applicable PR checks including CodeQL. |

fix(python): use dim as the embedding size for OpenAI-compatible models
Allow OpenAIEmbeddings.ndims() to use an explicitly configured dim for model names outside the three built-in OpenAI names, so schemas can be built for compatible models. Preserve existing model defaults and request behavior. Add regression coverage for the resulting Arrow schema dimensions and for all known OpenAI model dimensions. |

feat: support Hugging Face storage integrations with optional token Secrets (#4775)
Adds `HUGGINGFACE` and an optional token Secret reference to the
existing storage integration methods. The same SQL transport handles
create, describe, list and drop. Only a Secret reference is stored in
integration metadata; mixed-provider credential options are rejected.
```python
from lancedb.storage_integration import SecretReference
info = db.create_storage_integration(
"private_hub", "hf://datasets/acme/private/raw/",
storage_provider="HUGGINGFACE",
huggingface_token_secret=SecretReference(
"hf_token", database="shared", namespace_path=("credentials",),
),
)
print(info.configuration_instructions)
info = db.describe_storage_integration("private_hub")
names = list(db.list_storage_integrations())
db.drop_storage_integration("private_hub")
```
Omit the token Secret for anonymous access at Hugging Face's default
anonymous
rate limits. A tokenless integration does not use a cluster's Hugging
Face token:
```python
info = db.create_storage_integration(
"public_hub", "hf://datasets/acme/public/raw/",
storage_provider="HUGGINGFACE",
)
```
```sql
CREATE STORAGE INTEGRATION public_hub
STORAGE_PROVIDER = 'HUGGINGFACE'
STORAGE_PREFIX = 'hf://datasets/acme/public/raw/';
```
```sql
CREATE STORAGE INTEGRATION private_hub
STORAGE_PROVIDER = 'HUGGINGFACE'
STORAGE_PREFIX = 'hf://datasets/acme/private/raw/'
HUGGINGFACE_TOKEN_SECRET = shared.credentials.hf_token;

feat: accept GCP credentials Secret in storage integration clients (#4771)
Adds GCP inputs to the existing database-owned storage integration
methods. GCP takes one Secret reference; the Secret stores the complete
application credentials JSON as an opaque string. The same methods and
SQL transport handle create, describe, list and drop.
```python
info = db.create_storage_integration(
"gcs", "gs://customer-data/raw/", storage_provider="GCP",
gcp_credentials_json_secret=SecretReference(
"gcp_json", database="shared", namespace_path=("credentials",),
),
)

DROP STORAGE INTEGRATION gcs;
```

feat: accept Azure inputs in storage integration clients (#4759)
Register Azure Blob integrations through Flight SQL using an explicit
storage account and three Secret references for tenant ID, client ID and
client secret. Extends the database-owned integration APIs with
provider-specific inputs while keeping the same create, describe, list
and drop operations.
```python
info = db.create_storage_integration(
"customer_blobs", "az://customer-data/raw/",
storage_provider="AZURE", azure_storage_account="customeraccount",
azure_tenant_id_secret="tenant", azure_client_id_secret="client",
azure_client_secret_secret="credential",
)
print(info.configuration_instructions)
info = db.describe_storage_integration("customer_blobs")
names = list(db.list_storage_integrations())
db.drop_storage_integration("customer_blobs")
```
Sync and async connections accept the same options. Use
`SecretReference` for cross-database or namespace qualification. Values
remain in Secrets; returned metadata includes only references and setup
guidance.
```sql
CREATE STORAGE INTEGRATION customer_blobs
STORAGE_PROVIDER = 'AZURE'
STORAGE_PREFIX = 'az://customer-data/raw/'
STORAGE_AZURE_STORAGE_ACCOUNT = 'customeraccount'
STORAGE_AZURE_TENANT_ID_SECRET = public.tenant
STORAGE_AZURE_CLIENT_ID_SECRET = public.client
STORAGE_AZURE_CLIENT_SECRET_SECRET = public.credential;
DESCRIBE STORAGE INTEGRATION customer_blobs;

feat: manage property graphs defined over tables
Replaces #4322, keeping only its property graph defined over tables. A property graph maps node labels and relationship types to existing tables of its namespace, in the shape of SQL/PGQ's `CREATE PROPERTY GRAPH`. It stores only that definition: a query reads the tables as nodes and edges through SQL `GRAPH_TABLE`, as they are when it runs. - **Rust:** `Connection::create_property_graph` takes a `PropertyGraphDefinition` of `NodeTable`s and `EdgeTable`s. `describe_property_graph`, `drop_property_graph` and `list_property_graphs` manage it. - **Python:** `lancedb.graph` has `NodeTable`, `EdgeTable` and `Endpoint`. Sync and async connections gain `create_property_graph`, `open_property_graph`, `drop_property_graph` and `list_property_graphs`, and a `PropertyGraph` handle describes its graph. - **Support:** remote connections only. Local connections raise `NotImplementedError` in Python and return `NotSupported` in Rust. ```python import lancedb from lancedb.graph import EdgeTable, Endpoint, NodeTable db = lancedb.connect("db://demo", api_key="...") db.create_property_graph( "social", nodes=[NodeTable("person", key="person_id", label="Person")], edges=[ EdgeTable( "knows", label="KNOWS", source=Endpoint("src_id", references=("person", "person_id")), destination=Endpoint("dst_id", references=("person", "person_id")), ) ], ) db.execute_query(""" SELECT * FROM GRAPH_TABLE (social MATCH (p:Person)-[:KNOWS]->(f:Person) WHERE p.age > 30 COLUMNS (p.name AS person, f.name AS friend)) """).read_all() ``` |

fix!: support opt-in PKCE for device-code login (#4747)
## Problem and change
Some Keycloak client policies require S256 PKCE during device-code
login. Sending those parameters unconditionally breaks interoperability
with providers that expect standard RFC 8628 requests.
Configure device login with `OAuthFlow::DeviceCode(DeviceCodeOptions)`,
following the existing authorization-code options pattern.
`DeviceCodeOptions::new()` keeps PKCE disabled; `.use_pkce(true)` sends
an S256 challenge during device authorization and its matching verifier
during token polling. There is no automatic downgrade, and enabling PKCE
preserves the existing token-cache identity. Python, Node, and CLI
conversions retain ordinary device login without PKCE.
OIDC discovery and token requests now include a versioned User-Agent.
`env!("CARGO_PKG_VERSION")` is expanded at compile time and embeds the
version in the binary; no Cargo environment variable is needed when
running an installed binary or native binding.
The supported-flows guide documents the Rust-only device PKCE option and
its default.
## Rust API migration
BREAKING CHANGE: `OAuthFlow::DeviceCode` now carries
`DeviceCodeOptions`. Replace construction with
`OAuthFlow::DeviceCode(DeviceCodeOptions::new())` or
`OAuthFlow::DeviceCode(Default::default())`, and match with
`OAuthFlow::DeviceCode(_)`. Import `DeviceCodeOptions` from
`lancedb::remote` to opt into PKCE. Python and TypeScript public APIs
are unchanged.
## Validation
- `cargo +1.97.1 test --locked -p lancedb --features remote --lib
remote::`: 679 passed, including PKCE-on/off polling, option defaults,
User-Agent headers, and cache identity.
- `cargo +1.97.1 test --locked -p lancedb-python -p lancedb-nodejs --lib
test_device_code_conversion`: both native-binding conversion tests
passed.
- `cargo +1.97.1 test --locked -p lancedb --features remote --doc
remote::`: 6 passed, including the new options example and updated
session examples.
- `cargo +1.97.1 test --locked -p lancedb-cli --lib auth::tests::`: 11
passed.
- `cargo +1.97.1 fmt --all -- --check` and `git diff --check`: passed.
- A compiled version-string check ran successfully with
`CARGO_PKG_VERSION` unset at runtime.

feat: add a CLI release binary (#4751)
Package the standalone lancedb CLI with every stable and beta GitHub release. Publish archives for Linux x86_64, Linux ARM64, and Apple Silicon macOS, along with SHA-256 checksums, licenses, and third-party notices. Synchronize the CLI version with the SDKs and validate that release tags match both manifests. Add PR and manual packaging dry runs, runtime compatibility checks, and smoke tests of extracted executables. GitHub release creation now waits for all three archives to pass validation; SDK registry publishing remains independent. Update installation instructions and the release checklist. Linux binaries target glibc 2.28, retaining existing x86_64 CPU requirements; macOS binaries target macOS 14 or newer. |

feat: use SQL for remote view lifecycle
Stacked on #4675. Remote view create, describe, list, and drop now execute SQL. CREATE returns the stored definition, resolution defaults, and Arrow schema from the same execution; DESCRIBE VIEW returns that metadata and SHOW VIEWS supports scoped pagination. `drop_view_async()` returns a `job_type="query"` handle whose single `job.id` is the SQL query UUID. Waiting drains the query result once and caches completion; `describe_query(job.id)` works on the submitting connection. Completion means catalog removal, with physical cleanup continuing separately. Query handles have no registry history and cannot be reopened through `open_job()`. |

feat: use parameterized SQL for remote secrets
Stacked on #4674. Remote Secret creation, rotation, description, listing, and drop now use the SQL backend. Writes bind the credential to `CREATE SECRET name AS $1` or `ALTER SECRET name AS $1`, keeping values out of SQL text. Description returns metadata; listing uses namespace-scoped continuation tokens. The existing synchronous APIs submit a SQL query and wait internally through the same query-job adapter as function operations. The single query identity is retained internally; no registry job or extra query ID is introduced. Pollable shared results contain status or metadata and never credential values. --------- Co-authored-by: Xuanwo <github@xuanwo.io> |

feat: use SQL for remote function lifecycle
Remote function registration, exact-version lookup, listing, and drop now execute SQL through the Flight client. Registration waits for the durable image build and catalog publication before yielding its typed `FunctionVersion`. SQL also covers source-inclusive description and pinned metadata updates. Registration and drop handles use `job_type="query"`; the single `job.id` is the SQL query UUID and can be inspected with `describe_query()` on the submitting connection. Waiting drains the SQL result once and caches completion for repeated waits. The drop boolean reports catalog removal; physical cleanup continues separately. Query handles have no registry history and cannot be reopened with `open_job()`. |

feat: add database storage integration APIs (#4618)
Adds database-owned S3 storage integrations with Secret-style namespace
paths in a separate keyspace. Use a regular database under the cluster
root for bootstrap integrations and Secrets. `default` is an example
name, with no enforced or automatically provisioned database; `system`
remains read-only. Authentication uses either an IAM role or two
existing Secret references, including cross-database references;
configuration metadata never contains credential values.
### Python experience
```python
catalog = lancedb.connect_catalog("https://my-server.example", api_key="secret")
db = catalog.connect_database("default")
info = db.create_storage_integration(
"raw", "s3://customer-bucket/raw/",
aws_role_arn="arn:aws:iam::123456789012:role/lancedb-access",
aws_region="us-east-1",
)
print(info.configuration_instructions)
info = db.describe_storage_integration("raw")
print(list(db.list_storage_integrations()))
db.drop_storage_integration("raw")
```
For static credentials, replace `aws_role_arn` with
`aws_access_key_id_secret=SecretReference("s3_key_id",
database="default")` and
`aws_secret_access_key_secret=SecretReference("s3_secret_key",
database="default")`, imported from `lancedb.storage_integration`. Pass
`namespace_path` to address nested namespaces. Async database
connections expose the same APIs; listing is lazy. All four client
operations execute SQL through the existing SQL transport, with typed
Arrow result decoding and name-based listing cursors.
### SQL experience
```sql
CREATE STORAGE INTEGRATION default.public.raw
STORAGE_PROVIDER = 'S3'
STORAGE_PREFIX = 's3://customer-bucket/raw/'
STORAGE_AWS_ROLE_ARN = 'arn:aws:iam::123456789012:role/lancedb-access'
STORAGE_AWS_REGION = 'us-east-1';
DESCRIBE STORAGE INTEGRATION default.public.raw;
SHOW STORAGE INTEGRATIONS IN default.public;
DROP STORAGE INTEGRATION IF EXISTS default.public.raw;
CREATE STORAGE INTEGRATION default.public.raw
STORAGE_PROVIDER = 'S3'
STORAGE_PREFIX = 's3://customer-bucket/raw/'
STORAGE_AWS_ACCESS_KEY_ID_SECRET = default.public.s3_key_id
STORAGE_AWS_SECRET_ACCESS_KEY_SECRET = default.public.s3_secret_key;
```
CREATE and DESCRIBE return configuration and a single sentence of setup
guidance. IAM mode also returns the deployment role principal, stable
external ID, customer trust policy, and prefix-scoped permissions
policy. Registration does not verify access. Creation requires namespace
CREATE_STORAGE_INTEGRATION plus parent USAGE; Secret references require
source database, namespace, and Secret USAGE. Describe requires object
USAGE; drop requires OWNERSHIP. SQL supports GRANT/REVOKE for these
objects and their creation privilege.
Includes client documentation and Flight SQL regression coverage; no
dedicated storage-integration REST endpoints are used. Local
builds/tests are excluded by request.

docs: fix table, accuracy and structure problems found in the pre-launch review (#4745)
## Summary Fixes the problems a page-by-page review of the docs found before launch, after checking each one against the current source and, where noted, the code. The matching fixes for the dataset and Geneva pages, which live in `lancedb/docs`, are in lancedb/docs#402. **Tables** - `integrations/embedding/cohere`: each input-type description was split across two table rows and wrapped in literal quotes (`"`search_document`"`). Now one row per type. - `integrations/embedding/gemini`: removes the same stray quotes from the task-type table. - `integrations/ai/langchain`: the MMR search table's `kwargs` row was missing a cell, so its description sat under Type. - Six reranker pages (answerdotai, cohere, colbert, jina, openai, voyageai): closes the backtick before `_relevance_score`. - `indexing/vector-index`: finishes a cell cut off at "with scalar". - `sql/dql/dedupe`: labels the empty header cell in the resolution table. **Corrections** - `curation/sampling`: sampling works in LanceDB Embedded through the Python SDK, so the page is available in both, with the SQL sections marked Enterprise. - `feature-engineering/index`, `add-computed-column`: automatic refresh is on by default for each computed column and takes effect once a deployment enables its scheduler. `refresh-column` already said so; these two implied it was off. - `indexing/scalar-index`, `indexing/index`: `LABEL_LIST` accelerates `array_has_all`/`array_has_any`; `array_contains_*` doesn't exist. Also merges scalar-index's two "nested fields" sections into one. - `integrations/embedding/ibm`: lists the four current models from `CURRENT_MODELS` (it listed a deprecated one) and explains that the default stays a legacy ID so existing tables reload with their model. - `integrations/reranking/openai`: the class is `OpenaiReranker`, not `OpenAI()`. - `integrations/ai/synthetic-data-kit`: the CLI is `synthetic-data-kit` throughout, each step runs one command, each step passes the file it writes to the next, and `save-as` uses `-f`/`-o`. - `integrations/data/dlt`: `secrets.toml` defines `api_token`, which the pipeline reads, and the run command runs the file the page creates. - `search/vector-search`: the multivector walkthrough connected to Enterprise in step 1 and a local path in step 2. It now runs locally throughout, with a note on connecting to Enterprise, and is renamed so it doesn't read as a duplicate of the short section above. **Structure and wording** - `integrations/embedding/nvidia`: adds headings, and drops test-suite details aimed at contributors. - `integrations/ai/genkit`: makes the retrieval test a real heading and describes the query step. - `integrations/data/voxel51`: replaces a raw MkDocs `!!! note` with a `<Note>`. - `sql/ddl/table`, `sql/ddl/job`: "Errors and limits" is a real heading, not bold text. - `curation/windowing`: sidebar title matches the curation overview ("Rank and Deduplicate"). - `deployment/storage`, `basics/agentic-skills`: fixes a garbled sentence and a stale reference to the quickstart. **Checked:** no new Vale alerts on the changed pages. Assembled together with lancedb/docs#402, the site passes `mint validate` and `mint broken-links --check-anchors --check-redirects`. Every changed page was reviewed in a local preview. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

Update ci/check_cargo_lock.py and its regression tests to allow pruning dependency edges while their target packages remain in Cargo.lock. Removing the CLI from the Python source distribution can disable optional features such as Axum tracing, even though other SDK dependencies still require the tracing package. |

docs: list features in the landing page comparison table (#4743)
## Summary Replaces the generated availability table under **Compare features** on the landing page with a hand-written list of features, grouped by area, with separate Embedded and Enterprise columns. The generated table listed every page that declares `availability`, including overview and basic CRUD pages. Rows such as "Overview" appeared three times without context, and pages like Insert, Update, Database and the integrations showed up as if they were features. | Area | Features | | --- | --- | | Search | Vector, full-text and hybrid search, filtering, reranking, query plans, distributed search | | Indexing | Vector, full-text and scalar indexes | | SQL and curation | SQL, aggregation, sampling, joins, ranking and deduplication, near-duplicate detection, chunking, changes since a version, views | | Feature engineering | Computed columns, materialized views, embedding registry | | Training | PyTorch data loader, permutations, distributed training | | Data management | Branches, compaction and cleanup, background jobs, Real Time engine | | Security | Authentication, authorization | Each ✅/❌ matches the linked page's `availability` on `main`; SQL, which declares none, is Enterprise-only. Functions are left out until it's settled whether they are published. The same list, limited to 1.10 features, is in the Enterprise 1.10 editions in lancedb/docs#398. Checked by assembling the docs site with this change: `mint validate` passes and `mint broken-links --check-anchors --check-redirects` finds no broken links. Vale reports no new warnings. After this merges, the committed `lancedb` skill in lancedb/docs needs a rebuild (`make assemble && make skill`). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

fix(python): add a Blob V2 array construction helper (#4734)
Fixes #4733 PyArrow expects Blob V2 storage structs when constructing a record batch and cannot infer the extension array from raw bytes. LanceDB already converts binary values during ingestion, but batch writers had no supported array constructor. Add `lancedb.schema.blob_array(payloads)` for iterables of inline bytes and nulls, using the same extension type resolver as `blob()`. The helper preserves empty blobs and null blobs and works with both pylance's type and LanceDB's fallback. Document the descriptor fields, exclusive inline/external representations, batch construction, and existing binary conversion in synchronous and asynchronous `create_table` / `add` APIs. Validation: - Reproduced the reported `ArrowTypeError` on the original code; both new regression cases fail against the original schema module. - 256 focused blob tests and schema doctests passed; one optional PyAV test skipped. - Both new regression cases also passed with PyArrow 25, with and without pylance imports. - Python package Ruff checks and formatting passed. - MkDocs build passed, with an existing unrelated `SecretReference` cross-reference warning. Repository-wide Ruff reports 48 existing errors in `docs/web-tests`. <!-- lance-gatekeeper-fix:v1 agent=20d1a296d76ff5eb914c0848428a747a generation=1 --> Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> |

WITH(...)` sections (also gated — the automatic-refresh scheduler is still dev/staging-only). - Thread one running example (video frames → GPU extract/caption → dedup → auto-refreshing materialized view) through Functions, materialized views, and the LeRobotDataset integration guide instead of a separate tutorial. - Rename "LanceDB OSS"/"OSS" to "LanceDB Embedded"/"Embedded" throughout (52 files); activate the existing availability-comparison mechanism on `basics/offerings.mdx` for a full feature-by-feature comparison table. |

feat(python): add NVIDIA Nemotron embedding provider
Adds a Python `nvidia` embedding provider for Nemotron 3.5 Embed 1B and 8B. It works with NVIDIA's hosted API and self-hosted NIM `/v1` endpoints, and uses the existing `openai` client. The OpenAI provider can't send NVIDIA's passage/query input types or pick Nemotron's dimensions. - Documents are embedded as `passage`, searches as `query`. - Default dimensions are 2048 (1B) and 4096 (8B), and `dim` is checked against each model's supported range. Self-hosted model IDs need an explicit `dim`. - Response count, order, dimensions and values are checked. Null and empty text get a null vector without a request. - Each request is retried on its own with LanceDB's retry policy. Invalid input or responses fail immediately. - `NVIDIA_API_KEY` is only sent to the hosted API. Custom endpoints need an explicit `api_key` (a `$var:` reference), and endpoints restored from table metadata must be allowed with `allow_endpoint`. - Request dimensions are sent through `extra_body`, preserving the NVIDIA wire contract while supporting the declared minimum `openai==1.6.1`. Python and text only. Docs are in `integrations/embedding/nvidia`. Originally authored by Taylor (@tsmithv11). ### Testing - `test_nvidia_embeddings.py`: 45 passed, 2 deselected with both the locked `openai==2.44.0` and minimum `openai==1.6.1`. These use the real OpenAI client with mock HTTP transport and real local tables. - Embedding, registry, field-metadata and trust suites: 163 passed, 4 skipped, 10 deselected. - Historical live experiments: hosted 8B passed a five-request smoke test; hosted 1B returned HTTP 500. No live request was made in this stage, so current hosted 1B availability was not verified. Enterprise coverage uses the repository mock HTTP server, not a live deployment. |

feat(python): add CombinedFieldsQuery for BM25F full text search
Add a typed Python `CombinedFieldsQuery` for BM25F search across multiple columns. The query mirrors Lance's combined-fields semantics with ordered per-column boosts and AND/OR term matching. Convert it in both directions at the PyO3 boundary, including nested Boolean queries, and document the Python typed convenience entry. Closes #4652. |

feat(node): expose targetPartitionSize on IVF index options (#4594)
The Node SDK's vector index options only take `numPartitions`. The Rust index builders (`target_partition_size` in `rust/lancedb/src/index/vector.rs`) and the Python SDK already support a target partition size, so this adds `targetPartitionSize` to `IvfPqOptions`, `IvfRqOptions`, `IvfFlatOptions`, `HnswPqOptions` and `HnswSqOptions` and passes it to their builders. When both are set, `numPartitions` is used, as it is for Rust and Python callers. The reason to want it: an index built from a partition count records no target partition size, so `table.optimize()` splits and joins it against the index type's default and can merge small partitions down to one or two. Building with a target records it in the index details, and optimize keeps to it. https://github.com/lance-format/lance/pull/10154 fixes this on the Lance side for indexes built from a partition count; this lets Node users set the size directly. The new tests build IvfPq, IvfFlat, IvfRq, IvfHnswPq and IvfHnswSq indexes with `targetPartitionSize` and check the size recorded in the index details, and check that `numPartitions` wins when both are set. Each option's doc comment states that index type's default target. Docs regenerated with `pnpm run docs`. |

fix(python): implement remote namespace and table existence checks (#4725)
Remote Python connections inherited the unsupported-operation stubs for `namespace_exists` and `table_exists`, so both raised `NotImplementedError` even when namespace and table operations worked. Add the missing remote overrides, async methods, and PyO3 bindings using the existing namespace describe and table open paths. Only an explicit not-found result returns `False`; permission, transport, and server errors propagate. This preserves authentication, dynamic headers, retries, and nested namespace handling, and rechecks cached tables before reporting that they exist. The async namespace helper also recognizes native `NamespaceNotFound` errors so missing local namespaces return `False`. The table and namespace guides document Python remote support and distinguish it from the unsupported `exists` routes used by direct REST namespace clients. Validation: - All 40 focused regression cases pass, covering successful and missing lookups, local and remote namespaces, dynamic headers, permission/server errors, invalid table identifiers, and cached tables that disappear. - The original inherited stubs reproduce the reported `NotImplementedError`; the local namespace regression reproduced the native missing-namespace `RuntimeError` before its fix. - Full remote connection suite: 255 passed. Local namespace tests: 14 passed. - `cargo clippy --quiet -p lancedb-python --features remote --lib`, `cargo fmt --all`, Python Ruff lint, and Python formatting checks pass. - Root `ruff check .` reports 48 existing errors in documentation examples under `docs/web-tests`; the Python subtree passes and those unrelated files are unchanged.

docs: add guide for using LanceDB in VS Code extensions
Closes #1849 This was lancedb/docs#371. After lancedb/docs#355 moved the open-source pages, their navigation and the snippet tests into this repository's `docs/web` and `docs/web-tests`, that PR could no longer merge there, so I've moved the same change here. ## Why #1849 asks for an example of LanceDB in a VS Code extension, because people kept running into problems there (#927, #1713). An earlier attempt, #3682, added a README link. @prrao87 asked for something else instead: a quick guide on the docs site, under **Integrations › AI Platforms & Frameworks**, showing how to use LanceDB in an extension and what results look like. The author of #3682 agreed and closed it. This PR is that guide. ## What it adds - **`docs/web/integrations/ai/vscode.mdx`**: a new page, also added to `docs/web/docs.json`. It builds a small extension with two commands. One indexes the workspace's Markdown into a LanceDB table using the built-in `huggingface` embedding function, so no API key is needed. The other searches it by meaning. The page covers the parts that are specific to VS Code: - storing the table under `context.storageUri` instead of a relative path, which is the cause of #927; - `@types/node` ≥ 22 and `skipLibCheck`, which covers #1713 and the DOM-type errors from `apache-arrow`/onnxruntime typings; - pinning `apache-arrow` inside LanceDB's peer range; - marking `@lancedb/lancedb` and `@huggingface/transformers` as esbuild externals, and removing `node_modules/**` from the template's `.vscodeignore`; - storing each file's URI so a hit opens in the right folder of a multi-root workspace; - building one VSIX per platform with `vsce package --target`, with a table mapping each target to LanceDB's native package, and a note that the sample's local model (via `onnxruntime-node`) doesn't run on Alpine; - keeping the Transformers.js model cache in `globalStorageUri`, which only works if it's loaded with `import()`; - a troubleshooting table listing each error message with its cause and fix. - **`docs/web-tests/ts/vscode_search.ts`** and **`vscode_search.test.ts`**: the LanceDB code the page shows (connect, chunk, index, search), plus jest tests for it. - **`docs/web-tests/ts/vscode_extension.ts`**: the extension's `src/extension.ts`. Jest can't run it because it needs the VS Code extension host, so it was tested in a real extension instead (see below). This follows the precedent of `integrations.ts`. - **`docs/web/snippets/vscode_search.mdx`** and **`vscode_extension.mdx`**: generated with the command in CONTRIBUTING.md. ## Changes from lancedb/docs#371 - **New paths only.** The page, tests and snippets are the same content, at their paths in this repository. - **One link.** `/tables/update` doesn't exist under `docs/web`, so the `mergeInsert` link now points to `/ingestion/merge-insert`. - **Heading anchors.** Every heading now has an explicit `{#anchor}`, as CONTRIBUTING.md asks. ## How I tested it - **Snippet tests.** In this repository at `c2c8269f`, `vscode_search.test.ts` passes (2 tests) with the pinned `@lancedb/lancedb` 0.31.0. On Windows the `npm test` script fails before it starts, because it runs `node` on the `.bin/jest` shell shim. I ran `node --experimental-vm-modules node_modules/jest/bin/jest.js --testEnvironment jest-environment-node-single-context vscode_search` instead. - **Lint.** `biome ci` is clean for the three new files, and they carry the SPDX header that `license-header-check.yml` looks for. - **Snippets.** I regenerated them with CONTRIBUTING.md's command, `mdx_snippets_gen.py -s docs/web-tests/py -s docs/web-tests/ts -s docs/web-tests/rs -o docs/web/snippets`, run with `python` since I don't have `uv`. It reproduces the two new snippet files exactly, once the Windows CRLF endings are normalised. As CONTRIBUTING.md warns, it also rewrites `build_with_ai_agents.mdx`, `integrations.mdx`, `search.mdx` and `storage.mdx`. I left those out. - **Links.** `mint broken-links` from `docs/web` reports no entries on the new page, and its three internal links (`/embedding/quickstart`, `/ingestion/merge-insert`, `/search/full-text-search`) resolve to pages here. - **Real extension.** I built a sample extension from exactly the code on the page, scaffolded with `yo code` (TypeScript + esbuild) and using `@lancedb/lancedb` 0.39.0. I ran it with `@vscode/test-cli` in VS Code 1.140 on Windows x64. The integration test runs both commands against a six-file workspace and checks the top hits. The "Sample results" block on the page is copied from that run, and after the review fixes below it reproduces line for line in VS Code 1.141. - **Multi-root workspace.** A second test configuration opens two folders that both contain `docs/auth.md`. It types a query and picks the top hit through the real picker, then checks that the right folder's file opens at the right line. It fails on the code before the review fix and passes after it. - **Packaged VSIX.** I packaged `vsce package --target win32-x64` (200 MB, or 148 MB with the onnxruntime trimming in the Tip). Then I unpacked it outside the project and ran the same tests against the unpacked copy, so they couldn't pick up the project's `node_modules`. They pass. - **Negative checks behind the troubleshooting rows:** - With `node_modules/**` left in `.vscodeignore`, activation fails with `Cannot find module '@lancedb/lancedb'` and the commands report `command '…' not found`. - Without the externals, esbuild fails with `No loader is configured for ".node" files`. - Installing LanceDB into a project that already has `apache-arrow` 21 fails with `ERESOLVE`. - `require("@huggingface/transformers")` returns a different `env` object from `import()`. - **Rendering.** For lancedb/docs#371, `mint dev` rendered the page, its 14 code blocks and the sidebar entry. I haven't re-rendered it from `docs/web`; only the paths, one link and the heading anchors changed. **Not tested:** - macOS. I couldn't reproduce the read-only working directory from #927; the page's fix (an absolute storage path) doesn't depend on the OS. - Linux and macOS VSIX builds. ## Notes for reviewers - I added `_distance` to `.select(...)`, because LanceDB warns that it will stop adding the column automatically. ## AI disclosure I used Claude Code to research the issue and its history, write the sample extension, the tests and this page, move the change here, and draft this description. I ran every check listed above myself, and the outputs quoted on the page come from those runs. 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

docs: adopt Embedded/Distributed terminology across docs and SDKs (#4713)
## Summary Adopts the product terminology guide across the docs site pages, SDK docstrings and error messages. "LanceDB OSS" and local mode become **LanceDB Embedded**. "Remote" as the execution model becomes **LanceDB Distributed**, which LanceDB Enterprise provides. Where free vs paid is the point, pages contrast "LanceDB Embedded (open source)" with "LanceDB Enterprise". This is a first trial of the Embedded name, so reviewers can judge it in context. - **Embedded vs Distributed** for where execution runs (`optimize()`, consistency, branching, maintenance). Main pages define it once: "LanceDB Enterprise runs LanceDB Distributed: …" - **LanceDB Cloud** is kept only for legacy-Cloud specifics (`db://` region, the brute-force KNN limit) and marked legacy. "Cloud and Enterprise" becomes Enterprise or Distributed. - **Plan executor** becomes "executor" or the fleet name. - **Error messages** change, e.g. `optimize is not supported for remote tables.` → `... in LanceDB Distributed.` Tests that match on them are updated. - **Vale rules** (`EmbeddedName`, `OSSProduct`, `RemoteExecution`, `DistributedEnterprise`, `LegacyCloud`, `InternalNames`) enforce the terms in prose. Unchanged: identifiers (`availability.oss`, the `remote` module and feature, `RemoteTable`, `db://`), heading anchors, internal code comments, and Geneva. ## Evidence - Rust lib tests for the changed messages and the Python tests in `test_remote_db.py`, `test_materialized_views.py` and `test_table.py` pass locally. - Not run locally: - The Node tests: `remote.test.ts` and `table.test.ts` have updated assertions. - Vale. - The `experimental_functions`-marked materialized-view tests. - `docs/src` API reference was hand-edited to match the docstrings rather than regenerated. ## Merge Risk **Door:** two-way; prose and message text only. **Blast Radius:** `docs`, `error-messages`: callers matching on old error strings would break.

docs: show stateful class Functions
The Functions page only showed a plain function, so it never said where a class's `__init__` runs. Users loading a large model need to know it is not the client: registration reads the signature and ships the source. This adds a section on class Functions: `__init__` runs once per instance on the worker, then `__call__` per row or batch and `close()` on retirement, state is per instance, and `__init__` parameters are initialization fields set per binding. The example's test asserts that registering the class does not construct it. |

docs: correct the documented default retry statuses (#3964)
#2349 changed the default retryable status codes to `[409, 429, 500, 502, 503, 504]`, but only the Rust docstring was updated. The Python and TypeScript bindings — and the generated TypeScript API reference — still document the old `[429, 500, 502, 503]`. The actual default is set in `ResolvedRetryConfig::try_from` in `rust/lancedb/src/remote/retry.rs`, and `rust/lancedb/src/remote/client.rs` already documents it correctly. This brings the other three in line. Docs only — no behavior change. Split out from #3963 per the "one problem at a time" guidance in `CONTRIBUTING.md`. |

feat(nodejs): add col() expression builder for camelCase column names
## Summary Fixes #3211 by exposing the shared Rust/DataFusion expression builder through Node bindings. Case-sensitive references such as `col("firstName")` can be composed and passed to `where()`, while SQL strings remain supported. The expression-object representation follows [the design requested on #3290](https://github.com/lancedb/lancedb/pull/3290#discussion_r3632371998). That earlier PR remains open; no claim is made that the issue was unclaimed or that maintainers have selected this implementation. ## Review corrections - Construct the named native struct correctly and parse casts through `arrow_schema::DataType`. - Preserve numeric values: use Int64 only for JavaScript safe integers; retain Float64 otherwise. Explicit `litInt` rejects unsupported numbers with a documented `RangeError`. - Correct test syntax/API calls and align SQL assertions with the shared dialect, including reserved and case-sensitive names. - Use typed, isolated temporary test tables with cleanup, and cover an actual large-number filter threshold. - Document the public methods and commit generated API documentation. Synced with current main `0bceaaf3` through a normal merge. The diff is limited to seven Node source/test/config files and eleven generated documentation files; no Rust core change. ## Validation [Linux validation run](https://github.com/Ganesh1729-ui/lancedb/actions/runs/38244794288) on Node 24 / Rust 1.97.0 with the repository's `ci` profile and `remote,lancedb/metrics-otel` features: - Rebuilt native addon, TypeScript build, Biome, Rust formatting and native Clippy pass. - Expression/query/Arrow/table suites: **1,129 passed**; expression suite repeated: **42 passed**. - Using the original JavaScript numeric dispatch with the rebuilt addon: **8 regressions fail, 2 controls pass**. - Strict TypeDoc generation passes. Final local typing/docs/lint checks pass; the PR source equals the validated source except for the separate validation workflow, which is excluded from this PR. Full provider/model/S3, other feature combinations and OS/Node matrices were not run in this follow-up. Upstream checks and maintainer review remain separate. ## AI assistance AI was used for implementation, review and testing. No prior human review is claimed. |

fix(embeddings): default Cohere to embed-multilingual-v3.0, the v2.0 models are retired (#4698)
Cohere retired `embed-english-v2.0`, `embed-english-light-v2.0` and `embed-multilingual-v2.0` on April 4, 2026 ([deprecations](https://docs.cohere.com/docs/deprecations), which lists `embed-english-v3.0`, `embed-multilingual-v3.0` and `embed-v4.0` as the embedding alternatives). `CohereEmbeddingFunction` still defaulted to `embed-multilingual-v2.0`, so every call without an explicit `name` fails. The default is now `embed-multilingual-v3.0`, the multilingual v3 model, and the retired models are removed from the docstring and the Cohere integration page (the page also listed `embed-english-v2.0` as the default, which did not match the code). The docs example, its generated snippet, the docs test and the slow Cohere test use the new name. This changes the default vector size: `ndims()` returns 1024 for `embed-multilingual-v3.0`, where the old default gave 768. Tables created from a schema that uses `cohere.ndims()` get 1024-dimension vectors from now on. A table that already holds 768-dimension vectors from the retired model needs a re-embed with a current model, since the old model can no longer be called. The `ndims()` entries for the v2 names are left as they are. Test: `test_cohere_default_model_is_not_a_retired_v2_model` in `python/python/tests/test_embeddings.py` checks the default name and that `ndims()` is 1024. The repository's pytest session could not be run for this change (its `conftest.py` needs a newer native module than the released wheel); the body of that test was run against the released `lancedb` 0.40.0 with this version of `cohere.py` in place, where it passes, and it returns `embed-multilingual-v2.0` / 768 without the change. ruff check and format are clean on the touched Python files. No Cohere request was made.

feat: add a cascade option to drop_database (#4697)
The remote catalog could only drop an empty database: it always asked
the server for a restricted drop.
`DropDatabaseRequest::cascade`, `drop_database(..., cascade=True)` in
Python and `dropDatabase(name, { cascade: true })` in TypeScript ask the
server to drop everything in the database first. The name stays taken
until the server finishes cleaning up the dropped objects' storage. A
restricted drop remains the default.

fix: use SQL for all remote materialized view APIs (#4673)
Remote materialized-view APIs now use SQL for the full lifecycle. Create and refresh already submit SQL; this change moves describe, paginated listing, and drop onto `DESCRIBE MATERIALIZED VIEW`, `SHOW MATERIALIZED VIEWS`, and `DROP MATERIALIZED VIEW`. Async create, refresh, and drop return the existing Job handle with `job_type = "query"`. The handle has one `id`: the connection-scoped SQL query ID, also accepted by `describe_query`. Submission starts the query, the job drains its result once, and repeated waits reuse the completed result. Synchronous drop waits for catalog removal; physical cleanup proceeds in the background. Listing uses namespace-scoped keyset pagination with opaque resume tokens. Streamed and deferred SQL responses share the same path. Adds transport coverage and updates Python/TypeScript documentation for query-backed drop jobs. --------- Co-authored-by: Xuanwo <github@xuanwo.io> |

fix(python): support native blob conversion in pandas and batches (#4647)
Plain local blob v2 scans tried to open a pylance dataset before reaching LanceDB's byte-fetch path, so `to_pandas(blob_mode="bytes")` failed when the optional dependency was absent. Batch readers also had no `blob_mode` option. Route supported blob v2 pandas conversions through the native Arrow path. Add `blob_mode` to sync and async batch readers, convert payloads during iteration, and expose the converted schema without fetching the first batch. Apply conversion after reranking and retain the default descriptor behavior. Clean up scanner error punctuation and remove the misleading plain-scan suggestion. Bytes mode retains the existing `to_arrow` restrictions for legacy/list blobs, remote tables, and namespace query pushdown. Lazy pandas handles and legacy pandas scans still require pylance; sync FTS/hybrid batching remains unsupported. Validation: - UV-managed editable Python development build completed successfully. - The absent-pylance regression tests fail against the original query implementation and pass with this change. - Blob and query suites: 403 passed, 1 skipped, 1 deselected. - Remote query suite: 190 passed. - Python-tree Ruff lint/format checks and the async reader Pyright check pass. Repository-wide Ruff reports existing errors outside the Python tree.

fix: correct remote materialized view refresh results and options (#4672)
Remote materialized-view refreshes drained the SQL result and then fabricated `mode=rebuild`, `rows_written=<total view rows>`, and `source_version=0`. This made incremental refreshes report incorrect statistics. Make these three result fields optional across Rust, Python, and TypeScript, and leave them unset for remote SQL refreshes. Remove the post-refresh row count request. Local refreshes continue to populate all metrics, and `version` remains the view version observed after completion. Remote per-operation statistics remain unavailable until the SQL job adapter can retrieve them. Expose the forced-rebuild option through the Rust builder, synchronous/asynchronous Python refresh and job methods, and TypeScript refresh. Remote `full=true` sends `WITH (full = true)`; the default lets the server choose its refresh mode. Local source-version pinning and remote job cancellation are preserved. Local refresh regression tests respect the `experimental-functions` build gate, while remote refresh coverage also runs in default builds. Validation: - Rust: 20 materialized-view tests and 21 remote SQL tests passed with `remote,experimental-functions`; `cargo fmt --all` passed. - Python: rebuilt the extension in the uv-managed environment. The default build passed 23 tests with 27 feature-dependent skips. The opt-in build passed 61 tests with 3 expected default-build-only skips, covering the materialized-view suite and 14 async query-serialization cases from current main. Python Ruff lint and formatting checks passed. - TypeScript: default and opt-in native builds and TypeScript compilation passed. The default build passed 5 tests with 10 expected feature-dependent skips; the opt-in build passed all 14 materialized-view tests with the default-build-only test skipped. Lint/format checks and documentation generation passed. - Repository-wide `ruff check .` reports 48 pre-existing violations in unchanged `docs/web-tests` files; `ruff check python` passes.

fix: read legacy blob columns through blob APIs (#4649)
Legacy blob v1 columns were rejected by LanceDB's blob validation and omitted from `blob_columns()`, even though the pinned Lance reader already supports them. Accept both blob versions in read validation and discovery so `fetch_blobs`, `fetch_blob_files`, and `fetch_blob_ranges` can read legacy payloads through the existing native reader. Keep list-nested blobs excluded from row-based reads and document how to fetch legacy blobs using explicit row IDs. Regression coverage checks sync and async APIs, independently written Lance datasets, ordering and duplicates across fragments, null and empty blobs, lazy seeking, ranges, and deleted rows. Fixes #4644 Validation: - Both new Python regressions failed on the original implementation with the reported legacy-column rejection and empty discovery result, then passed with the fix. - Python blob suite: 202 passed, 1 skipped. - Remote blob tests: 29 passed. - Focused Rust blob unit tests with `remote`: 13 passed. - Rust blob integration suite with `remote`: 59 passed, including legacy storage 2.0 and 2.1. - Rust compile and Clippy checks with `remote`, tests, and examples passed. - Python package Ruff lint and format checks passed; Rust formatting passed. - Repository-wide `ruff check .` reports 49 existing errors in unchanged `docs/web-tests` examples; the Python package is clean. <!-- lance-gatekeeper-fix:v1 agent=02b7edcbfa8ff0e7fad4615159249b3e generation=1 --> --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> Co-authored-by: Xuanwo <github@xuanwo.io> |

fix(remote): make HTTP timeout errors actionable (#4650)
Remote `create_table` reader uploads can exceed the read deadline while waiting for response headers, but reqwest's main error message only says "error sending request". Make HTTP and retry errors explicitly identify timeouts and name the relevant `client_config.timeout_config` settings and environment variables, preserving typed sources, request metadata, and retry classification. Document that the read timeout covers waiting for headers during upload. This implements the issue's diagnostic option: creation still uses one streaming request, so large or slow readers may require a longer `client_config.timeout_config.read_timeout`. Validation: - 48 focused Rust client, error, and retry tests passed. Regression coverage holds an upload open until its read timeout and also exercises TLS connection timeouts, with and without retries. - 8 Python create-table and HTTP/retry error tests passed in the uv-managed environment after rebuilding the extension, including reader creation with read and overall timeouts. - `cargo check --quiet --features remote --tests --examples` passed. - `cargo clippy --quiet --features remote --tests --examples` passed. - Rust formatting and Python package Ruff lint/format checks passed. - Repository-wide `ruff check .` reports 49 existing findings under `docs/web-tests`; those files are unchanged.

fix: gate experimental local functions behind an opt-in feature (#4688)
Published SDK builds currently expose local SQL computed columns and materialized-view execution that are not ready for release. Add the opt-in `experimental-functions` Cargo feature to the Rust core and forward it through the Python and Node bindings; published packages leave it disabled. Local declarations and refreshes now return `NotSupported` before mutating tables or spawning jobs, including prepared materialized-view creation. Remote Cloud/Enterprise client operations, Python UDF packaging, ordinary eager `add_columns`, and access to existing data remain available. Stored metadata and write protections stay active, and shared server commit helpers remain usable. CI covers both feature configurations. Existing local execution tests run with the feature enabled; default-build regressions cover early rejection, unchanged table versions, existing metadata protections, and normal eager transforms. API and source-build documentation explain the opt-in. Validation: Rust library tests pass with the feature disabled (1,869 tests) and enabled (1,947 tests), plus three default-build integration regressions. Python and TypeScript bindings were rebuilt and tested in both configurations, including mocked remote requests; Rust formatting, Python package lint, TypeScript lint/build, and generated docs were checked. Repository-wide Ruff still reports 48 pre-existing errors in unchanged `docs/web-tests` files. |

fix(rust): prevent oversized SQ remap panics (#3861)
## Summary - preflight IVF-SQ and IVF-HNSW-SQ storage segments touched by compaction - preserve unknown legacy fragment coverage as conservatively affected - cover both fixed-size vector and multivector SQ storage dimensions - reject only affected partitions whose fixed-size-list child exceeds Arrow's `u32` take-index limit - return an actionable `InvalidInput` error before Arrow can panic ## Root cause Arrow 58 builds fixed-size-list child indices with `u32`. For a large SQ partition, `partition_rows * vector_dimension` can exceed `u32::MAX`; the child range then wraps inside `take_fixed_size_list`, producing the reported `ArrayData::slice` assertion during index remapping. The preflight now reads raw segment metadata, mirrors Lance's fragment-bitmap selection (including `None` as affected/unknown), opens only affected vector segments, and checks their actual storage quantizer and partition sizes. It derives the stored dimension for both `FixedSizeList` vectors and flattened `List<FixedSizeList>` multivectors. Stable-row-ID datasets, deferred remapping, custom remappers, unaffected segments, non-SQ indexes, safe partitions, and no-op compactions are unchanged. Because the upstream Arrow kernel still has the limit, an affected index must be recreated with default IVF partitioning (or enough partitions to stay below the reported maximum) before compaction. This changes the failure from a process panic to a targeted recovery error; it does not silently alter index structure. ## Validation - `cargo fmt --all -- --check` - `cargo test --quiet --features aws,remote -p lancedb table::optimize::tests --lib` - `cargo test --quiet --features remote -p lancedb table::create_index::tests::test_create_index_ivf_hnsw_sq` - `cargo check --quiet --features remote --tests --examples` - `cargo clippy --quiet --features remote --tests --examples -- -A clippy::redundant-pub-crate` (the allowance is for pre-existing Rust 1.97 warnings in remote-table code) Fixes #2866 <!-- lance-gatekeeper-fix:v1 agent=ba2f07b1ee6f9e68a0de1961c164f70e generation=1 --> --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> Co-authored-by: Xuanwo <github@xuanwo.io> |

fix(python): expose optimize compaction options (#3870)
## Summary - expose typed compaction options on synchronous and asynchronous table optimization - translate validated Python options into native Lance compaction settings - document the row-based steady-state limit and first-pass/source-budget caveats - carry the Lance beta.15 fragment-exclusion option through the typed Python API ## Root cause The native Python optimize binding always constructed default compaction settings, and the public AsyncTable API offered no way to lower the fragment row target. Wide-row fragments therefore remained compaction candidates on every later optimize call, repeatedly rewriting the accumulated table. ## Limitations This is an explicit row-based mitigation, not byte-native task sizing or a hard memory cap. Callers must derive target_rows_per_fragment from expected row size. Existing oversized fragments are rewritten whole on the first pass; max_bytes_per_file limits output file size rather than compaction memory; and source budgets admit whole planned tasks, so a budget below the first task performs no compaction. Splitting tasks by a byte budget or returning a planner error requires a Lance-side change. ## Validation - cargo check --release -p lancedb-python - cargo clippy --quiet -p lancedb-python - cargo fmt --all --check - ruff format --check python tests - ruff check python tests - uv run --no-sync pytest python/tests/test_table.py -k optimize_compaction -q (16 passed) Fixes #2325 <!-- lance-gatekeeper-fix:v1 agent=9b58eee0c79040b19540e259af0e676c generation=1 --> --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> Co-authored-by: Xuanwo <github@xuanwo.io> |

fix!: reject unsupported remote connection and table options (#4486)
Fixes #4399. Remote connections currently discard local-only settings, including table write options that determine storage format. The synchronous Python client also binds the fourth positional `create_table` argument to `on_bad_vectors`, so an intended overwrite is sent as a create. This change aligns the remote Python signature with `DBConnection.create_table`, preserves the legacy remote timeout keywords, and raises `ValueError` for other unknown connection keywords. The shared Rust client rejects unsupported connection, create, and open options before sending HTTP requests; open validation also runs before a table-cache hit. Python reports these as `NotImplementedError`, including explicit `enable_v2_manifest_paths=False`. Supported Enterprise connection-level storage options remain available. This implements option 2 from the issue: explicit rejection. It deliberately does not add unverified server write parameters. Calls that previously supplied ignored options must omit them to use server-managed storage and caching. Database URI prefixes are already preserved on current main and are unchanged here. Regression tests cover Python sync/async, TypeScript create/open calls, and the Rust remote client, including empty-table creation, overwrite mode, and cached table handles. Python API documentation describes the behavior and corrected positional order. Reconciled with main at `0ea932da`, preserving upstream blob and error-handling tests and updating the Python test that previously expected open options to be ignored. Validation on the merged source: - Rebuilt the Python native extension; 304 tests passed across remote options, database, remote database, and session suites. - Rust remote database suite: 135 passed. Rebuilt the Node native extension; TypeScript remote suite: 62 passed. TypeScript compilation and documentation generation passed. - Full Python SDK lint and formatting pass (159 files); full TypeScript lint and formatting pass (66 files). Rust formatting and `git diff --check` pass. - Repository-wide Python lint/format reports existing issues in unchanged `docs/web-tests` files (49 lint findings and 11 formatting files). Environment: Ubuntu under WSL2, Linux x86-64, CPython 3.12.13, Rust 1.97.0, and Node.js 22.16.0. Locked dependencies and the repository `ci` build profile. Remote tests use HTTP fixtures; this does not claim validation against the original ARM64 single-node deployment. Documentation review follow-up: added a draft Enterprise migration note in `docs/web/basics/sdk.mdx`. It explains that `db://` connections reject local session/cache and per-table storage/write options, while supported connection-level Enterprise storage options remain available. Following the repository's release conventions, the note stays in an MDX comment below the migration list until the behavior is released. Vale 3.24.0 with the pinned LanceDB style package reports no findings; `git diff --check` passes. This follow-up changes documentation only. BREAKING CHANGE: Remote connections now reject unsupported local session/cache and per-table storage/write options instead of silently ignoring them. Callers must omit these options and use server-managed storage and caching; supported Enterprise connection-level storage options remain available. Integration with current main preserves its synchronous API signatures, including the remote `create_table(mode=None)` default, and the table compatibility defaults. The positional-order repair is already on main via #4608; this PR retains the distinct unsupported-option rejection behavior. CI follow-up: the inherited IVF search-effort test occasionally measured recall 0.375 against its unchanged 0.5 threshold after random index training. A matching local reproducer observed this once in 30 builds. The fixture now places the eight exact neighbors together, preserving the 16-partition setup, two writes, all probe/precedence assertions, and the recall threshold. The adjusted fixture returned recall 1.0 in 100 builds; the full query and remote suites passed (102 tests). This stabilizes test data and does not change search behavior or promise production recall. --------- Co-authored-by: Xuanwo <github@xuanwo.io> |

fix(python)!: align synchronous table method signatures (#4498)
Closes #4396. Calls written against `Table` can fail or bind different arguments when used with `RemoteTable`. Align the affected sync signatures, positional order, and defaults; preserve renamed remote keywords as deprecated aliases. Share legacy vector configuration and tokenizer inference, forward index tuning and timeout options, and accept `fast_search` consistently. Preserve current upstream conversion behavior: local `to_polars(batch_size=...)` returns a LazyFrame; remote tables accept the same argument signature but raise the documented unsupported-operation error and direct callers to `table.search().to_polars()`. The abstract `Table` method retains its unsupported-operation error, with the implementation confined to `LanceTable`. Regression coverage checks argument binding, deprecated aliases, option forwarding, native behavior through both wrappers, HTTP index requests, and remote conversion rejection. The merge preserves current tokenizer defaults, remote query defaults, HNSW-PQ support, and unsupported-operation handling. Runtime validation at `c4fb01f2` (Linux x86_64, uv-managed Python 3.12.15): - Focused Ruff lint and formatting passed for all four changed Python files. - Rebuilt and installed the current native extension successfully with the repository's `ci` Cargo profile. - Seven regression suites passed: `test_errors.py`, `test_table_signatures.py`, `test_remote_db.py`, `test_table.py`, `test_index.py`, `test_fts.py`, and `test_query.py`: **874 passed, 1 deselected**, with slow and S3 tests excluded. - CI caught an abstract-base conversion regression in the initial merge. The existing error-contract test reproduced it locally (1 failed, 7 passed); restoring the implementation to `LanceTable` fixes it while preserving signature parity. - Full-root Ruff reports 49 lint errors and 11 files needing formatting, all in unchanged upstream `docs/web-tests` files. The four changed Python files pass both checks. - Validated against upstream `197403e8`, using Lance 15.0.0-beta.1 and LanceDB 0.41.0-beta.14 bindings. Historical validation before this merge: 618 tests passed and one was deselected. That result does not establish correctness of the current merge. The original client-side reproduction produced nine argument-binding errors without contacting a server; the initial regression suite failed 32 cases before the fix and passed 39 after it. Documentation review follow-up: restored the `batch_size` parameter description on the abstract `Table.to_polars` method so it appears in the public API reference. This adds six docstring lines and changes no runtime behavior. After this edit, all 47 focused error-contract and signature tests pass; changed-file Ruff lint/format and `git diff --check` pass. Repository-wide Ruff still reports the same 49 findings and 11 formatting files in unchanged `docs/web-tests`. The full documentation site and seven-suite runtime run were not repeated for this documentation-only follow-up. The reported ARM64 production-server deployment has not been recreated. HTTP integration tests use the repository's local mock server. BREAKING CHANGE: Remote synchronous table methods now use the positional argument order and defaults documented by `Table`. Migrate calls using the former remote-only positional order to named arguments, particularly `create_index` and `search`; pass `index_type` by keyword to `create_scalar_index`. Remote scalar and vector index creation now default to `replace=True`; specify `replace=False` to retain rejection of an existing index. Renamed remote keywords remain supported as deprecated aliases, as documented above. --------- Co-authored-by: Xuanwo <github@xuanwo.io> |

fix: inherit Lance defaults for IVF RQ quantization (#4585)
`IvfRq()` forced `num_bits=1` through Python's Rust binding, overriding Lance's five-bit default. The shared native index creation path also substituted one bit when the Rust or Node builder left the value unset. Make Python's bit count optional and forward only explicit values. Use `RQBuildParams::default()` for an unset native bit count, and omit unset values when dispatching to pylance for accelerator builds. Update the Python, Rust, Node, and vector-index documentation. New indexes with an unset bit count now inherit Lance's default, currently five bits, across Python, Rust, and Node. Five-bit vector codes use roughly five times the storage of one-bit codes, plus other index overhead. This also changes reader compatibility: indexes created with `num_bits >= 2` use a newer on-disk layout that some older LanceDB versions cannot read. Upgrade readers to versions that support multi-bit IVF_RQ, or explicitly set `num_bits=1` (for example, `IvfRq(num_bits=1)` in Python) when sharing indexes with readers limited to one-bit IVF_RQ. Validation: - Reproduced six regression failures before the fix: one-bit default metadata, rejected `None`, and incorrect remote/accelerator forwarding. - After merging `main` through `b762ec22`, rebuilt both native bindings against Lance 15.0.0-beta.1. Python validation passed with 106 tests and 15 optional Ollama skips. Coverage includes the full index suite, omitted and explicit bit counts, reading Lance-created IVF_RQ indexes, accelerator forwarding, CUDA-unavailability handling, timeout validation, remote requests, and table/namespace listing behavior. - Rust formatting and Python package Ruff lint/format checks pass. Node `pnpm lint`, `pnpm build` (including TypeScript checks), `pnpm run docs`, the full connection suite, and the existing IVF_RQ regression pass. Generated documentation adds no further changes. The merge preserves upstream's explicit RaBitQ heading anchor alongside the `IvfRq()` example and five-bit default/reader-compatibility guidance. Repository-wide `ruff check .` still reports 49 existing errors in unchanged documentation examples under `docs/web-tests`; root formatting also finds 11 unchanged documentation example files. The Python package checks pass.
