Will Jones	1d6e00b902	feat: progress bar for `add()` (#3067 ) ## Summary Adds progress reporting for `table.add()` so users can track large write operations. The progress callback is available in Rust, Python (sync and async), and through the PyO3 bindings. ### Usage Pass `progress=True` to get an automatic tqdm bar: ```python table.add(data, progress=True) # 100%\|██████████\| 1000000/1000000 [00:12<00:00, 82345 rows/s, 45.2 MB/s \| 4/4 workers] ``` Or pass a tqdm bar for more control: ```python from tqdm import tqdm with tqdm(unit=" rows") as pbar: table.add(data, progress=pbar) ``` Or use a callback for custom progress handling: ```python def on_progress(p): print(f"{p['output_rows']}/{p['total_rows']} rows, " f"{p['active_tasks']}/{p['total_tasks']} workers, " f"done={p['done']}") table.add(data, progress=on_progress) ``` In Rust: ```rust table.add(data) .progress(\|p\| println!("{}/{:?} rows", p.output_rows(), p.total_rows())) .execute() .await?; ``` ### Details - `WriteProgress` struct in Rust with getters for `elapsed`, `output_rows`, `output_bytes`, `total_rows`, `active_tasks`, `total_tasks`, and `done`. Fields are private behind getters so new fields can be added without breaking changes. - `WriteProgressTracker` tracks progress across parallel write tasks using a mutex for row/byte counts and atomics for active task counts. - Active task tracking uses an RAII guard pattern (`ActiveTaskGuard`) that increments on creation and decrements on drop. - For remote writes, `output_bytes` reflects IPC wire bytes rather than in-memory Arrow size. For local writes it uses in-memory Arrow size as a proxy (see TODO below). - tqdm postfix displays throughput (MB/s) and worker utilization (active/total). - The `done` callback always fires, even on error (via `FinishOnDrop`), so progress bars are always finalized. ### TODO - Track actual bytes written to disk for local tables. This requires Lance to expose a progress callback from its write path.

Will Jones	e6fd8d071e	feat(rust): parallel inserts for remote tables via multipart write (#3071 ) Similar to https://github.com/lancedb/lancedb/pull/3062, we can write in parallel to remote tables if the input data source is large enough. We take advantage of new endpoints coming in server version 0.4.0, which allow writing data in multiple requests, and the committing at the end in a single request. To make testing easier, I also introduce a `write_parallelism` parameter. In the future, we can expose that in Python and NodeJS so users can manually specify the parallelism they get.

Prashanth Rao	ed7e01a58b	docs: fix rendering issues with missing index types in API docs (#3143 ) ## Problem The generated Python API docs for `lancedb.table.IndexStatistics.index_type` were misleading because mkdocstrings renders that field’s type annotation directly, and the existing `Literal[...]` listed only a subset of the actual canonical SDK index type strings. Current (missing index types): <img width="823" height="83" alt="image" src="https://github.com/user-attachments/assets/f6f29fe3-4c16-4d00-a4e9-28a7cd6e19ec" /> ## Fix - Update the `IndexStatistics.index_type` annotation in `python/python/lancedb/table.py` to include the full supported set of canonical values, so the generated docs show all valid index_type strings inline. - Add a small regression test in `python/python/tests/test_index.py` to ensure the docs-facing annotation does not drift silently again in case we add a new index/quantization type in the future. - Bumps mkdocs and material theme versions to mkdocs 1.6 to allow access to more features like hooks After fix (all index types are included and tested for in the annotations): <img width="1017" height="93" alt="image" src="https://github.com/user-attachments/assets/66c74d5c-34b3-4b44-8173-3ee23e3648ac" />	2026-03-20 09:34:42 -07:00

Weston Pace	dd5aaa72dc	ci: modify check_lance_release.py to prefer stable releases over betas (#3146 ) When Lance 3.0.0 released the check_lance_release.py script did not make a PR for it because it was a pre-release. This change may not be perfect but it always ranks stable releases above non-stable releases.	2026-03-17 09:21:30 -07:00
marca116	3a200d77ef	fix: pre-filtering on hybrid search (#3096 ) When using hybrid search with a where filter, the prefilter argument is silently inverted. Passing prefilter=True actually performs post-filtering, and prefilter=False actually performs pre-filtering.	2026-03-16 21:48:42 -07:00
