1. Refactored every client (Rust core, Python, Node/TypeScript) so “namespace” usage is explicit: code now keeps namespace paths (namespace_path) separate from namespace clients (namespace_client). Connections propagate the client, table creation routes through it, and managed versioning defaults are resolved from namespace metadata. Python gained LanceNamespaceDBConnection/async counterparts, and the namespace-focused tests were rewritten to match the clarified API surface. 2. Synchronized the workspace with Lance 5.0.0-beta.3 (see https://github.com/lance-format/lance/pull/6186 for the upstream namespace refactor), updating Cargo/uv lockfiles and ensuring all bindings align with the new namespace semantics. 3. Added a namespace-backed code path to lancedb.connect() via new keyword arguments (namespace_client_impl, namespace_client_properties, plus the existing pushdown-ops flag). When those kwargs are supplied, connect() delegates to connect_namespace, so users can opt into namespace clients without changing APIs. (The async helper will gain parity in a later change)
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)
