- create_materialized_view now takes either query= or source+select (folds in
the old create_view builder) and returns a MaterializedView handle whose
.wait() blocks on initial population. create_view is removed -- it was
misnamed (it built a *materialized* view, while CREATE VIEW means the plain
non-materialized view the engine also supports).
- MaterializedView.refresh() and the remote Table.refresh_column() now return a
JobHandle directly, so tbl.refresh_column("c").wait() needs no db.job(...)
wrapper. db.job(id) is narrowed to reconnect-by-id (stored id / SQL / REST).
- rename View/AsyncView -> MaterializedView/AsyncMaterializedView (+ exports).
- tighten the replace path: only a not-found error on the pre-drop is benign;
real failures (perms/server) now surface instead of being swallowed.

LanceDB Python SDK
A Python library for LanceDB.
Installation
pip install lancedb
Preview Releases
Stable releases are created about every 2 weeks. For the latest features and bug fixes, you can install the preview release. These releases receive the same level of testing as stable releases, but are not guaranteed to be available for more than 6 months after they are released. Once your application is stable, we recommend switching to stable releases.
pip install --pre --extra-index-url https://pypi.fury.io/lancedb/ lancedb
