Function versions identify independent Function objects and their numeric revisions. Rust and Python expose the object ID, location, canonical decimal version, metadata, and availability separately from the OCI image digest. Computed-column applications carry the complete object reference, so existing bindings retain their identity after a name is removed and reused. Source authoring keeps the existing create_function/create_function_async, job wait, and column-binding APIs. The server coordinates baking followed by registration; users do not have to manage manifest digests to create a Function. The previous stored Function representation is intentionally unsupported. Existing contract tests and shared wire fixtures are migrated to the new model. This SDK change accompanies the final integration layer https://github.com/lancedb/sophon/pull/7887 in the Sophon stack: https://github.com/lancedb/sophon/pull/7885 → https://github.com/lancedb/sophon/pull/7886 → https://github.com/lancedb/sophon/pull/7887. A metadata-only revision can retain the same executable image; Function version numbers must not be used as image cache keys. --------- Co-authored-by: lancedb automation <robot@lancedb.com> Co-authored-by: Yang Cen <bubble-cal@outlook.com> Co-authored-by: Claude Fable 5.1 <noreply@anthropic.com>
LanceDB Documentation
LanceDB docs are available at docs.lancedb.com.
The SDK docs are built and deployed automatically by Github Actions
whenever a commit is pushed to the main branch. So it is possible for the docs to show
unreleased features.
Building the docs
Setup
- Install LanceDB Python. See setup in Python contributing guide.
Run
make developto install the Python package. - Install documentation dependencies. From LanceDB repo root:
pip install -r docs/requirements.txt
Preview the docs
cd docs
mkdocs serve
If you want to just generate the HTML files:
PYTHONPATH=. mkdocs build -f docs/mkdocs.yml
If successful, you should see a docs/site directory that you can verify locally.
Adding examples
To make sure examples are correct, we put examples in test files so they can be run as part of our test suites.
You can see the tests are at:
- Python:
python/python/tests/docs - Typescript:
nodejs/examples/
Checking python examples
cd python
pytest -vv python/tests/docs
Checking typescript examples
The examples depend on @lancedb/lancedb at file:../dist, so the package must be
built before running the tests. This uses pnpm; see the
Typescript contributing guide for the toolchain setup.
pushd nodejs
pnpm install
pnpm build
popd
Then you can run the examples by going to the nodejs/examples directory, which is a
separate pnpm package with its own lockfile:
pushd nodejs/examples
pnpm install
pnpm test
popd
API documentation
Python
The Python API documentation is organized based on the file docs/src/python/python.md.
We manually add entries there so we can control the organization of the reference page.
However, this means any new types must be manually added to the file. No additional
steps are needed to generate the API documentation.
Typescript
The typescript API documentation is generated from the typescript source code using typedoc.
When new APIs are added, you must manually re-run the typedoc command to update the API documentation. The new files should be checked into the repository.
pushd nodejs
# `pnpm docs` would invoke pnpm's built-in `docs` command, not the script.
pnpm run docs
popd
