## Summary - Fix `name in db` and `len(db)` for local Python connections with more than one page of tables. - Use `list_tables()` pagination instead of deprecated `table_names()` with its default 10-item page. - Add regression coverage with 20 tables so later pages are included. Fixes #2727. ## Validation - `python3 -m py_compile python/python/lancedb/db.py python/python/tests/test_db.py` - No-build Python harness that extracts and executes the edited `LanceDBConnection` pagination methods: passed - `uvx ruff check python/python/lancedb/db.py python/python/tests/test_db.py` - `uvx ruff format --check python/python/lancedb/db.py python/python/tests/test_db.py` Note: `uv run pytest python/tests/test_db.py::test_db_contains_and_len_include_all_table_name_pages -q` was attempted first, but it stayed in the broad Rust/PyO3 native extension build and was stopped before pytest started.
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)
