Lance Release	93b8ac8e3e	Bump version: 0.25.4-beta.1 → 0.25.4-beta.2	2025-11-19 20:24:46 +00:00
Jack Ye	1b78ccedaf	feat: support async namespace connection (#2788 ) Also fix 2 bugs: 1. make storage options provider serializable in ray 2. fix table.to_table() uri is wrong for namespace-backed tables	2025-11-19 12:23:50 -08:00
Mykola Skrynnyk	ca8d118f78	feat(python): support `to_pydantic` in async (#2438 ) This request improves support for `pydantic` integration by adding `to_pydantic` method to asynchronous queries and handling models that use `alias` in field definitions. Fixes #2436 and closes #2437 . <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - New Features - Added support for converting asynchronous query results to Pydantic models. - Bug Fixes - Simplified conversion of query results to Pydantic models for improved reliability. - Improved handling of field aliases and computed fields when mapping query results to Pydantic models. - Tests - Added tests to verify correct mapping of aliased and computed fields in both synchronous and asynchronous scenarios. <!-- end of auto-generated comment: release notes by coderabbit.ai -->	2025-11-19 11:20:14 -08:00
Wyatt Alt	386fc9e466	feat: add num_attempts to merge insert result (#2795 ) This pipes the num_attempts field from lance's merge insert result through lancedb. This allows callers of merge_insert to get a better idea of whether transaction conflicts are occurring.	2025-11-19 09:32:57 -08:00

Xuanwo	f77b0ef37d	ci: add timely lance release check (#2790 ) This PR will add a timely lance release check for lancedb which will auto bump lance while new tags released. --- This PR was primarily authored with Codex using GPT-5-Codex and then hand-reviewed by me. I AM responsible for every change made in this PR. I aimed to keep it aligned with our goals, though I may have missed minor issues. Please flag anything that feels off, I'll fix it quickly. --------- Signed-off-by: Xuanwo <github@xuanwo.io>	2025-11-19 16:43:41 +08:00

Will Jones	1cf3917a87	ci: make rust ci faster, get ci green (#2782 ) * Add `ci` profile for smaller build caches. This had a meaningful impact in Lance, and I expect a similar impact here. https://github.com/lancedb/lance/pull/5236 * Get caching working in Rust. Previously was not working due to `workspaces: rust`. * Get caching working in NodeJs lint job. Previously wasn't working because we installed the toolchain after we called `- uses: Swatinem/rust-cache@v2`, which invalidates the cache locally. * Fix broken pytest from async io transition (`pytest.PytestRemovedIn9Warning`) * Altered `get_num_sub_vectors` to handle bug in case of 4-bit PQ. This was cause of `rust future panicked: unknown error`. Raised an issue upstream to change panic to error: https://github.com/lancedb/lance/issues/5257 * Call `npm run docs` to fix doc issue. * Disable flakey Windows test for consistency. It's just an OS-specific timer issue, not our fault. * Fix Windows absolute path handling in namespaces. Was causing CI failure `OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: `	2025-11-18 09:04:56 -08:00
