Brendan Clement 8cc8acd30c docs: correct the cascade limit and remote stable-row-id guidance
The limits page still listed REFRESH MATERIALIZED VIEW ... CASCADE as
parsed but not implemented, while the refresh page says it depends on
the deployment's version. The row now says the same and links there.

The refresh page told deployment users to create a view's source with
new_table_enable_stable_row_ids. A db:// connection never sends that
option: RemoteOptions keeps only the Azure account name, and a remote
create_table sends only its mode and data. The page now says stable row
ids are set up on the deployment, which depending on its version may
give new tables them, refuse a view created through SQL over a source
without them, or convert the source when a view is created through its
REST API, and to check with its administrator.

The architecture, limits, table and database pages no longer say stable
row ids can never be enabled after creation, which that REST conversion
contradicts; they say the SDK can only give them to a table it creates.
The local heading now names the removed stable-row-id requirement
instead of promising that any table can be a source, and notes the
write-ahead-log checks that remain.

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

  1. Install LanceDB Python. See setup in Python contributing guide. Run make develop to install the Python package.
  2. 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
