Jack Ye 8f37234a86 docs: split feature engineering, move functions to Management
Feature engineering is now the overview plus one page per operation: add a
computed column, refresh a column, refresh a materialized view. Computed
columns covered declaring and filling on one page, which are separate decisions
with separate failure modes.

Functions move to Management, where the other catalog objects are, and absorb
the environment-mismatch guidance from the Enterprise page -- a symptom table
worth having beside the parameters that cause it.

The Enterprise feature-engineering page is merged into the overview. Two of its
claims were stale: create_materialized_view is implemented for db:// connections
in remote/db.py, so views are not local-only, and the tier is Enterprise rather
than 'Cloud and Enterprise'.

The REST reference leaves the sidebar. Mintlify only generates per-endpoint
pages from a navigation group -- hidden, dropdowns, global anchors and a
top-level openapi key were all tried -- so removing the group removes those
pages. The overview survives as an unlisted page, linked from SDKs & SQL, and
the spec still ships for anything that wants to read it directly.

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
