Summary

This release introduces significant features like async namespace support, IVF SQ indexing, and stable row IDs, while also deprecating macOS x86 support and refactoring namespace model usage.

⚠️ Breaking Changes

  • Support for macOS x86 architecture has been deprecated.
  • Namespace operations now use namespace models directly instead of previous methods. Users should update calls related to namespace operations to use the new direct model approach.

Migration Steps

  1. Review usage of namespace operations to align with the new direct use of namespace models.
  2. If encountering issues with macOS builds, note that x86 support is deprecated.

✨ New Features

  • Documentation scope reduced to only show API references.
  • Lance version bumped to 0.40-0-beta.2.
  • Lance now determines the default value for the `num_partitions` parameter.
  • Support added for vending namespace credentials.
  • Added `num_attempts` parameter to merge insert results.
  • Support for `to_pydantic` in asynchronous operations in Python.
  • Support for asynchronous namespace connection.
  • Implementation of `head()` functionality for remote tables.
  • Codex URL key updated.
  • Remote default features removed from lance-namespace-impls.
  • Support for stable row IDs via `storage_options`.
  • Support for server-side querying of namespaces.
  • IVF SQ index support added, along with HNSW aliases.
  • Use of REST namespace for the LanceDB Java SDK.
  • Java client builder made generic.
  • Vector type inference updated: defaults to float32 if input integers are outside the uint8 range.
  • Upgrade of lance-namespace Python package to version 0.3.2.

🐛 Bug Fixes

  • Schema metadata is now converted to strings for `JsonArrowSchema`.
  • Default value for namespace is now set to `None`.
  • Fixed issue where `.phrase_query()` was not functioning correctly.
  • Resolved error related to `table_names` at the root namespace.
