wait() (sync + async) only stopped on finished/stale/committed, so a job the server already reported as state=failed was polled until the (default 3600s) timeout, then raised a misleading TimeoutError instead of the real cause. A doomed backfill -- e.g. a multi-column REFRESH COLUMN of a scalar UDF -- hung the client even though get_job surfaced the failure within ~3s. Add a terminal failed branch that raises JobFailedError carrying the server error, exported from the package. Verified end-to-end against the cluster: raises in 3.6s instead of hanging. Unit-tested with a mock conn (sync+async, failure + success + committed paths). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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
