## Summary Add connection serialization and child namespace support to `LanceDBConnection`. - `DBConnection.serialize()` / `lancedb.deserialize()` for connection reconstruction in remote workers - Cache `namespace_client()` in `LanceDBConnection` to avoid repeated DirectoryNamespace builds - `LanceDBConnection` transparently delegates child namespace operations (open_table, create_table, list_tables, drop_table, create_namespace, etc.) to `LanceNamespaceDBConnection` via `_namespace_conn()` - Root namespace operations still go through the original Rust path - Generic worker property override mechanism: any `namespace_client_properties` key prefixed with `_lancedb_worker_` has the prefix stripped and overrides the corresponding property when `deserialize(data, for_worker=True)` - `LanceNamespaceDBConnection` stores `namespace_client_impl`/`namespace_client_properties` for serialization roundtrip --------- Co-authored-by: Claude Opus 4.6 (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
Usage
Basic Example
import lancedb
db = lancedb.connect('<PATH_TO_LANCEDB_DATASET>')
table = db.open_table('my_table')
results = table.search([0.1, 0.3]).limit(20).to_list()
print(results)
