Adds the derived-compute interface to the SDK:
- Database trait: create/list/drop_function, create/refresh/alter/
drop/list_materialized_view, list_jobs -- default implementations
return Error::NotSupported (NotImplementedError in python), so
existing Database impls are unaffected; local single-node
implementations are planned. BaseTable gains refresh_column with
the same default.
- RemoteDatabase/RemoteTable implement them against the server REST
routes (/v1/function/*, /v1/materialized_view/*, /v1/job/list,
/v1/table/{id}/refresh_column), with mock-HTTP unit tests.
- Connection/Table public methods, pyo3 bindings (FunctionInfo,
MaterializedViewInfo, JobInfo pyclasses), and python wrappers:
sync on the DBConnection base (shared by local and remote
connections), async on AsyncConnection; refresh_column on
LanceTable, RemoteTable, and AsyncTable.
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)
