From 1842c88f2c1c23bd688d6c23d12cddf519af459a Mon Sep 17 00:00:00 2001 From: "lancedb-gatefixer[bot]" <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> Date: Wed, 23 Sep 2026 14:22:40 -0700 Subject: [PATCH 01/38] fix(node): reject unsupported object row values (#4307) ## Cause Schema inference treated unrecognized objects as nested structs. Objects without enumerable fields produced no field paths, so schema matching dropped their columns before Arrow or blob conversion. Blob instances with own fields were mistaken for struct fields. ## Fix Walk only nonempty plain records as structs. Reject unsupported object values in scalar fields, nested structs, and list elements with the field path and row number. Preserve the object types already passed through to Arrow. Support for converting these new input types is tracked in #4270. Nested class instances with enumerable fields previously became structs; this change rejects them and is labeled `breaking-change`. ## Validation - `pnpm build` - `pnpm lint` - `pnpm test __test__/arrow.test.ts __test__/blob.test.ts __test__/table.test.ts --runInBand --silent` (626 passed) - `pnpm run docs` Fixes #4269 --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> --- nodejs/__test__/arrow.test.ts | 97 +++++++++++++++++++++++++++++++++++ nodejs/__test__/blob.test.ts | 21 ++++++++ nodejs/__test__/table.test.ts | 17 ++++++ nodejs/lancedb/schema.ts | 58 +++++++++++++++++---- 4 files changed, 184 insertions(+), 9 deletions(-) diff --git a/nodejs/__test__/arrow.test.ts b/nodejs/__test__/arrow.test.ts index 6c1d5ecba..df02b4936 100644 --- a/nodejs/__test__/arrow.test.ts +++ b/nodejs/__test__/arrow.test.ts @@ -601,6 +601,103 @@ describe.each([arrow15, arrow16, arrow17, arrow18])( );

Both PyO3 methods entered `block_on`, which panics when GC runs on a LanceDB Tokio worker. ## Fix Track Python blob handle closure atomically so `closed` is synchronous. `close()` marks the handle closed immediately and, when called on a Tokio thread, schedules the underlying async cleanup without blocking that thread. Reads and seeks after close fail immediately; ordinary callers still wait for cleanup. ## Validation - Rebuilt the Python extension with `uv run --extra tests --extra dev maturin develop --extras tests,dev`. - Ran the blob test file and remote blob handle test: 69 passed, 1 skipped. - Ran `cargo fmt --all`, `ruff format .`, and `ruff check .`.

That is deliberately **different** from `drop_materialized_view` and `drop_function`, which return as soon as the name is unbound and document that content may still be deleting. The view API is the newer one, and waiting is the semantic worth having; the other two are left alone rather than changing behaviour already released. ## Surfaces `Database` trait, the remote client, `Connection`, and the Python and Node bindings — matching where `drop_materialized_view_async` is already exposed.

Default `batch_size=1` preserves the existing payload. Each batched question sees only its document and the shared query; instructions/criteria stay unchanged. Prompts referencing `state.document` need adaptation. Concurrency still limits requests; retries remain SDK-managed. Batch-local IDs and ordered results preserve duplicate documents; invalid IDs/probabilities raise without fallback. Validation: **124 automated tests passed**, plus live search integrations in both modes. A **100-query live subset test of the initial implementation** (6,851 candidate pairs; `jev-1.13.0`, SDK 0.7.1, concurrency 32) passed: unbatched/batched calls **6,851/199**, median **877/351 ms**, p95 **9,446/598 ms**. Hybrid Hit@5/Hit@10 was **83%/89% vs 84%/90%**; vector/FTS results and exact configuration are in the [test report](https://github.com/lancedb/lancedb/blob/typesafe-request-batching/python/benchmarks/typesafe_batching.md). Ruff and MkDocs passed. The simplified batching flow also passed a fresh four-query live check: 292 candidate pairs, with 292 unbatched versus 8 batched calls.

From: Xuanwo Date: Thu, 24 Sep 2026 18:02:25 +0800 Subject: [PATCH 09/38] fix(python): warn instead of failing on local imports in @udf source (#4318) Since 0.40.0b8 (#4254), `@udf` raises when the packaged source imports a module from a local source tree that is neither shipped with `code=` nor named by a declared pip/conda package. That turned registrations that used to succeed into errors: - Callers that rewrite the packaged source before registering it now fail at decoration. Sophon's datagen integration suite inlines its test-module helpers this way, and `test_registered_udf_source_stands_alone_on_a_worker` fails on 0.40.0b8. - The check cannot know which modules a distribution installs. A declared package whose distribution name differs from its module (for example an internal library installed editable) is reported as local, and there was no way to proceed. This keeps the diagnosis but makes it a `UserWarning`, so registration behaves as it did before #4254 and still tells the author, at registration time, why the worker is likely to fail. --- python/python/lancedb/functions.py | 25 +++++++++++++------ .../python/tests/test_function_packaging.py | 18 ++++++++----- 2 files changed, 29 insertions(+), 14 deletions(-) diff --git a/python/python/lancedb/functions.py b/python/python/lancedb/functions.py index 380625f57..5f26b590e 100644 --- a/python/python/lancedb/functions.py +++ b/python/python/lancedb/functions.py @@ -26,6 +26,7 @@ import re import sys import textwrap import types +import warnings from collections.abc import Mapping, Sequence from datetime import date, datetime from typing import ( @@ -1527,9 +1528,14 @@ class _SourcePackager: return f"{name} = {_literal_source(value)}" def _require_importable(self, module_name: str) -> None: - """Refuse an import the Function's environment has no way to satisfy: - a module that lives in a local source tree, is not shipped with - ``code=``, and names no declared package.""" + """Warn about an import the Function's environment likely cannot + satisfy: a module that lives in a local source tree, is not shipped + with ``code=``, and names no declared package. + + A warning rather than an error: a distribution name need not match + the module it installs, so a declared package can still provide the + module, and callers may rewrite the packaged source before + registering it.""" top = module_name.partition(".")[0] if ( top in self._code_modules @@ -1543,10 +1549,12 @@ class _SourcePackager: roots = _installed_roots() if not locations or any(location.startswith(roots) for location in locations): return - raise ValueError( + warnings.warn( f"@udf source imports {module_name!r} from {locations[0]}, a local " - "module the Function's environment cannot import; ship it with " - f"code=[{top}] or declare the package that provides it in pip/conda" + "module the Function's environment may not be able to import; ship " + f"it with code=[{top}] or declare the package that provides it in " + "pip/conda", + UserWarning, ) @@ -1991,8 +1999,9 @@ def udf( place.

This adds `pause_job` and `resume_job` to the Rust core connection and the Python bindings (sync and async), posting to the server's `/v1/jobs/pause` and `/v1/jobs/resume` endpoints. A pause parks the job until it is resumed: its workers drain and stop. The outcome strings mirror the server's answers — a job finalizing its results reports `"committing"` and cannot be parked, and a resume before the drain is confirmed reports `"still_pausing"`; both are retried rather than failed. Resuming re-queues the job and its workers pick their work back up from checkpoints. Local connections report the operations as unsupported, like the rest of the jobs API. --- docs/src/js/classes/Connection.md | 44 ++++++++++++++++ nodejs/__test__/remote.test.ts | 21 ++++++++ nodejs/lancedb/connection.ts | 26 ++++++++++ nodejs/src/connection.rs | 28 ++++++++++ python/python/lancedb/_lancedb.pyi | 2 + python/python/lancedb/db.py | 53 +++++++++++++++++++ python/python/lancedb/remote/db.py | 16 ++++++ python/python/tests/test_remote_db.py | 23 ++++++++ python/src/connection.rs | 24 +++++++++ rust/lancedb/src/connection.rs | 16 +++++- rust/lancedb/src/database.rs | 33 ++++++++++++ rust/lancedb/src/remote/db.rs | 75 ++++++++++++++++++++++++++- rust/lancedb/src/remote/job.rs | 22 ++++++++ 13 files changed, 380 insertions(+), 3 deletions(-) diff --git a/docs/src/js/classes/Connection.md b/docs/src/js/classes/Connection.md index a51fb986a..f1aace87b 100644 --- a/docs/src/js/classes/Connection.md +++ b/docs/src/js/classes/Connection.md @@ -823,6 +823,28 @@ abstract openTable( *** +### pauseJob() + +```ts +abstract pauseJob(jobId): Promise +``` + +Pause a server-side job by id. + +The job's workers drain and it stays parked until resumed.

Basically, the existing code just calls a vector query + FTS query and dedups locally using the row ID. Since row ID is unsupported in WAL (currently), we update the algorithm to use the tables PK (which is required in WAL, and uniquely linked to a PK on updates). To enable PK-dedup branch, we've chosen to fallback on error rather than fire an exploratory query. Specifically, we issue the regular hybrid query, using row IDs, and when that fails with "WAL does not support row IDs" we fallback to the PK-based variant, and then cache the fallback for future calls from the same client. The alternative is that we chec if WAL is enabled before issuing the query. This would require a `get_lsm_write_spec` call, slowing down all the existing non-WAL paths unnecessarily. The ultimate goal is to get row ID supported in WAL, but that is pending stable row ID GA and subsequent integration into the enterprise stack. Once that lands, we will rip out the PK-based dedup that is only for WAL-enabled tables and use the existing row ID code. This is the main reason for building this adaptively. I had spec-ed out a refactor so that rather than duplicating code between python and rust we build this in rust and have python call that through PyO3. However, that made the reverse path (ie. ) more difficult. So I think the tradeoff of maintaining duplicate code in the short term for the ease of reverting this in the medium term (hopefully 2-3 months). --------- Co-authored-by: Claude Opus 5 --- python/python/lancedb/_lancedb.pyi | 3 + python/python/lancedb/_wal_hybrid.py | 282 +++++++++++++ python/python/lancedb/query.py | 130 +++++- python/python/lancedb/remote/table.py | 8 + python/python/lancedb/table.py | 21 + python/python/tests/test_wal_hybrid.py | 219 +++++++++++ python/src/table.rs | 15 + rust/lancedb/src/query.rs | 44 ++- rust/lancedb/src/query/wal_fusion.rs | 523 +++++++++++++++++++++++++ rust/lancedb/src/remote/table.rs | 292 ++++++++++++++ rust/lancedb/src/table.rs | 25 ++ 11 files changed, 1538 insertions(+), 24 deletions(-) create mode 100644 python/python/lancedb/_wal_hybrid.py create mode 100644 python/python/tests/test_wal_hybrid.py create mode 100644 rust/lancedb/src/query/wal_fusion.rs diff --git a/python/python/lancedb/_lancedb.pyi b/python/python/lancedb/_lancedb.pyi index 337b736ce..1f26ad6f4 100644 --- a/python/python/lancedb/_lancedb.pyi +++ b/python/python/lancedb/_lancedb.pyi @@ -514,6 +514,9 @@ class Table: async def set_lsm_write_spec(self, spec: LsmWriteSpec) -> None: ... async def unset_lsm_write_spec(self) -> None: ... async def get_lsm_write_spec(self) -> Optional[LsmWriteSpec]: ... + # WAL-PK-FUSION: delete both. + def hybrid_pk_fusion_learned(self) -> bool: ... + def note_hybrid_pk_fusion(self) -> None: ... async def checkpoint_lsm(self) -> None: ... async def flush_lsm(self) -> None: ... async def compact_lsm(self) -> None: ... diff --git a/python/python/lancedb/_wal_hybrid.py b/python/python/lancedb/_wal_hybrid.py new file mode 100644 index 000000000..67597950d --- /dev/null +++ b/python/python/lancedb/_wal_hybrid.py @@ -0,0 +1,282 @@ +# SPDX-License-Identifier: Apache-2.0 +# SPDX-FileCopyrightText: Copyright The LanceDB Authors + +"""WAL-PK-FUSION: hybrid search's primary-key fallback for MemWAL tables. + +Hybrid search joins its vector and full-text legs on `_rowid`, which a MemWAL +table cannot supply: the fresh tier has no stable row id, so the server rejects +`with_row_id` before it plans.

The default greedy policy keeps the smallest unassigned snapshot row ID and removes only its directly matching neighbors: For A < B < C, an A–B–C chain without an A–C edge keeps A and C. ```python from lancedb import vector_dedup view = db.create_materialized_view( "images_clean", vector_dedup("images", column="phash", distance_threshold=4), ) cleaned = view.table ``` The Python source expression captures the source version once at creation and waits for the materialized result by default. Use `dataset_version=...` for an explicit snapshot, `with_no_data=True` for declaration only, or `create_materialized_view_async(...)` for a job handle. AsyncConnection supports the same expression. It uses the existing MV REST endpoints and registry jobs, without opening a SQL query connection. Source names are exact root-namespace table names. Additional select/where/limit options are rejected for this source. The SQL declaration remains available: ```sql CREATE MATERIALIZED VIEW images_clean AS SELECT * FROM vector_dedup('images', 7, 'phash', 4); REFRESH MATERIALIZED VIEW images_clean; ``` This is the host-facing SQL entry point. The MV builder now accepts a typed native vector source; the Rust SDK also supports the same definition through `MaterializedViewDefinition::from_sql` and `prepare_definition`; `view.refresh().execute()` executes it locally. Hosts distribute its units using their existing job infrastructure. The raw `vector_duplicate_pairs` source remains available separately when callers want the pair relation. ## Implementation and contract - Use actual Rust Lance `13.0.0-beta.15` (`db53dcf367`); the native partition primitive computes pairs from index representations without source-vector aggregation or a Python pair loop. - Extend partitioned MV refresh with two dependent waves. Physical segment/partition tasks stream pairs through a bounded external sort, select direct representatives and write per-source-fragment bitmap artifacts. Source-fragment tasks start after every selection receipt completes and stream retained original rows, including blob payloads, into uncommitted output fragments. - Reuse normal blob write coercion and row-mask scans, including stable row-ID translation after compaction. Null vectors, isolated rows and source deletions are preserved correctly. Conflicting representative decisions across overlapping index scopes fail before publication. - Expose `dependency_units()` and `write_refresh_partition_with_inputs` alongside the existing plan/commit API. Receipts bind snapshot/configuration/policy/destination generation. Only a complete accepted set can publish; unfinished units restart, completed units can be reused. There is no pair-position checkpoint. - Use MV format 4 for dedup results and format 3 for native pairs; Python and TypeScript metadata readers recognize both. No source deletion or source row-ID migration occurs. Only same-segment/same-partition edges are covered. Quantized scores use symmetric represented-vector distances. Result materialization requires V2 data storage and is initially a native MV source, not an ordinary SELECT table function. Compressed vertex masks stay in memory; edge sorting spills to local disk. Unreferenced artifacts use normal Lance retention/cleanup and must be retained for the job's recovery window. ## Validation AWS Linux validation: - Native pair/result integration matrix passed: multiple segments/partitions, exact thresholds, empty output, cross-batch data, single-process pair parity, source preservation, lost receipts and publication guards. - Blob/null-vector/pinned-deletion tests passed with both row-ID modes, including compaction that changes physical row addresses. - Representative policy, forced external-sort spill and conflicting/corrupt artifact tests passed. - Full MV regression suite: 153 passed, 2 pre-existing ignored. Rust formatting and Clippy passed. - Python MV suite: 47 passed; TypeScript MV suite: 11 passed. Native bindings were rebuilt in project-local environments; formatting, lint and TypeScript docs passed. - Rust declaration doctests: 3 passed, including the complete local dedup example. - Companion host validation: 41 MV job tests passed (1 pre-existing ignored), full workspace Clippy passed, and the complete process-level CLI E2E suite passed (3 tests). Recovery exercises both selection and materialization waves. - A real CIFAR-10 pHash run used five actual registry-worker owners, completed 32 selection + 24 materialization tasks, and retained 49,846 of 50,000 rows with identical original values and image payloads. Host workflow performance measurements are recorded in the companion host PR. Cross-platform CI is still running. The previous remote-test bootstrap failed before Cargo tests with `401 Bad credentials`; the workflow fix described below is being validated by CI. No deployment or merge is performed. ## Python source validation AWS tests cover automatic and explicit snapshots, physical/stable row IDs, local and remote creation, sync/job/async-connection APIs, delayed refresh, strict options and identifier quoting. The native Python extension was rebuilt through the project's uv/maturin backend. Ruff, Pyright and the full MkDocs API-reference build passed; both new public symbols are rendered. A real 50,000-image FEv2 run disabled both Python SQL entry points and supplied an unreachable SQL endpoint. The new API still materialized the same 49,846 retained rows and original image payloads. Three recorded creation/refresh jobs completed 56 tasks each on all five registry-worker owners, and remained on source snapshot 3 after source latest advanced to 4. No worker or server wire-protocol changes were needed for this client entry point. Previous CI authentication failure: https://github.com/lancedb/lancedb/actions/runs/36334679276/job/108663151265. ## Review and CI fixes - Validate all JSON merge source fields before projection, rejecting unknown and duplicate names at every struct level. Missing/reordered fields and ordinary JSON merges remain supported. A checked-in 12-case integration matrix covers root fields, structs, lists, large lists, fixed-size lists and map values; rejected writes leave the table version and row count unchanged. - Match namespace connection MV method signatures to `MaterializedViewSource` in all four sync/async methods, fixing the Python 3.10 import failure from runtime override checks. - Restore the remote-test script's encrypted-CLI path: use the Actions token for artifact download and pass `SOPHON_READ_TOKEN` under the variable the decryption script consumes. The previous workflow omitted that variable and attempted the private release path, failing with HTTP 401. On the final head, remote CI passes: 1,464 Rust unit tests, the integration targets and doctests pass (3 unit tests ignored). AWS validation for these fixes: both review reproducers failed before their fixes and pass afterward; 55 merge tests, 29 cast tests and the standalone 7-case admission regression pass. Python 3.10.21 imports successfully; 90 MV/namespace tests, 14 JSON tests and four real namespace dedup cases pass. After `794b97a0`, the native binding was rebuilt again and the JSON suite rerun. Rust formatting/Clippy, Ruff and Pyright pass. Sophon's locked test compilation passes against the final SDK source for all seven affected crates. Extended runners, logs and benchmark artifacts remain local. Gatekeeper recommends approval on `794b97a0`, and the `breaking-change` label is set. Final CI: **49 checks passed, 3 expected skips, no failures or pending checks**, including remote tests, Python 3.10, minimum dependencies and Windows ARM Rust tests. All wheel builds pass after retrying the Linux matrix affected by transient AlmaLinux repository-metadata 404s. All code-review threads are resolved. The PR remains open for maintainer review and merge. --------- Co-authored-by: Yang Cen Co-authored-by: Lance Release --- .github/workflows/rust.yml | 3 +- Cargo.lock | 90 +-- Cargo.toml | 28 +-

SQL reads those as column names: ```ts await table.update({ values: { price: NaN }, where: "id = 1" }); // Error: Invalid input, Schema error: No field named "NaN". Valid fields are id, price. ``` `Infinity` and `-Infinity` fail the same way. The only workaround today is `valuesSql`. ## Fix Emit `CAST('NaN' AS DOUBLE)`, `CAST('Infinity' AS DOUBLE)` and `CAST('-Infinity' AS DOUBLE)` for these values. Finite numbers render as before. ## Tests - `__test__/util.test.ts` adds `toSQL` cases for `NaN`, `Infinity` and `-Infinity`. - `__test__/table.test.ts` adds "should let me update float values to NaN and Infinity", which updates a float column and reads the values back. - On `main`, the new cases fail with `No field named "NaN"`. - With the fix, all of `util.test.ts` and `table.test.ts` pass (344 tests). These were run against the published `@lancedb/lancedb@0.40.0-beta.11` native binary. - `biome check` is clean on the changed files. The Python SDK has the same issue in `value_to_sql`. That fix is in #4326. The fix was found and written by an AI agent (Breken) and checked against the tests above.

Any other handle still on an older version then fails with a missing-file error, and nothing tells the caller this can happen. #2470 asks for a docs note and a runtime warning. Fixes #2470 ## Scope - `AsyncTable.optimize` emits a `UserWarning` when `cleanup_older_than` rounds to 0 ms or less. `LanceTable.optimize` runs through it, so sync callers get the warning too. - The `cleanup_older_than` docstring on `Table.optimize`, `LanceTable.optimize`, and `AsyncTable.optimize` gets a `.. warning::` block, in the same style as the existing `delete_unverified` one. - Removed the function-local `import warnings` in `AsyncTable.optimize`. `warnings` is already imported at module level, and the local import would shadow it for the new check (`UnboundLocalError`). - `test_optimize` and `test_optimize_delete_unverified` intentionally use a 0 cleanup, so they now assert the warning with `pytest.warns`. Nodejs `cleanupOlderThan` is out of scope, since the issue is filed against the Python SDK. ## Tradeoffs Like the existing `retrain` deprecation warning, the warning is raised inside the async coroutine. For sync callers it is attributed to `asyncio/events.py` rather than the caller's line. Warning from both the sync and async entry points would duplicate the check for a small gain. ## Verification - Repro: a second handle checked out at an older version, then `optimize(cleanup_older_than=timedelta(0))` on the first. The second handle's read fails with `LanceError(IO) ... Not found: .../data/.lance`. Before this change no warning is emitted. After it, the `UserWarning` fires. - New tests `test_optimize_warns_on_zero_cleanup` (async, and checks that `timedelta(days=1)` and the default don't warn) and `test_optimize_warns_on_zero_cleanup_sync` fail on main (`DID NOT WARN`) and pass with the fix. The failing tests are in their own commit before the fix. - `pytest python/tests/test_table.py -m "not slow and not s3_test"`: all pass except `test_merge_insert`. That test's `timeout=timedelta(0)` assertion fails the same way on unmodified main on my machine. - `ruff format --check` and `ruff check` are clean on the changed files. Tests ran against the source tree with the `_lancedb` extension from the matching `0.40.0b11` wheel. The change touches no Rust.

The documented default is 10, and `AsyncHybridQuery` already falls back to `DEFAULT_HYBRID_LIMIT` (10). In `LanceHybridQueryBuilder`, each sub-query (vector and FTS) falls back to its own default of 10 rows. The fused result was then sliced with `limit=None`, i.e. not truncated at all. When the two legs match different rows, the caller gets the union. t = db.create_table("t", [{"text": ("dog" if i >= 20 else "cat") + f" {i}", "vector": [float(i), 0.0]} for i in range(40)]) t.create_index("text", config=FTS()) len(t.search(query_type="hybrid").vector([0.0, 0.0]).text("dog").to_arrow()) # before: 20, after: 10 For the same reason, `.offset(n)` without `.limit()` did not raise the sub-query limits to cover the skipped prefix; that only happened inside `if self._limit:`. ## Changes - Use `DEFAULT_HYBRID_LIMIT` when no limit is set, both for the sub-query limits (`limit + offset`) and for the final slice of the reranked results, matching `AsyncHybridQuery`. ## Test plan - [x] New `test_hybrid_query_default_limit` in `test_hybrid_query.py`. It is the sync counterpart of `test_async_hybrid_query_default_limit`, plus an `offset()`-without-`limit()` check. It fails before the fix (20 rows) and passes after. - [x] `pytest python/tests/test_hybrid_query.py python/tests/test_rerankers.py` - [x] `ruff format --check` / `ruff check` I have no local Rust toolchain, so I ran the tests against the released 0.39.0 native module with the changed Python files overlaid.

SQL reads those as column names: ```python table.update(where="id = 1", values={"price": float("nan")}) # ValueError: Invalid input, Schema error: No field named nan. Valid fields are id, price. ``` The same happens for `math.inf`, `-math.inf`, `np.nan` and `np.float32("inf")`, which go through the same float path. The only workaround today is `values_sql`. ## Fix Emit `CAST('NaN' AS DOUBLE)`, `CAST('Infinity' AS DOUBLE)` and `CAST('-Infinity' AS DOUBLE)` for these values. Finite floats render as before. The cast also lands correctly in `float32` columns. ## Tests `test_value_to_sql_nan_and_infinity` in `python/python/tests/test_util.py` updates `float64` and `float32` columns to NaN, +inf and -inf, then reads them back: - On `main`, it fails with `ValueError: Invalid input, Schema error: No field named nan`. - With the fix, it passes. All of `test_util.py` passes (75 passed, 1 skipped), and so do the update tests in `test_table.py` (`-k update`, 8 passed). - `ruff format --check` and `ruff check` are clean. NaN inside a list value (for example a vector) still fails, because Lance only accepts literals inside array values. This PR covers scalar columns only. The fix was found and written by an AI agent (Breken) and checked against the tests above.

With two searches of 3 rows each (`K=60`): | row | rank in its own list | score today | RRF score | |---|---|---|---| | 1 (top of list 1) | 1 | 1/61 | 1/61 | | 3 (third of list 1) | 3 | 1/63 | 1/63 | | 4 (top of list 2) | 1 | **1/64** | 1/61 | | 5 (second of list 2) | 2 | **1/65** | 1/62 | So the best hit of the second search ranks below the worst hit of the first, and the order of the lists passed in decides the fused ranking. `MRRReranker.rerank_multivector` already scores each list on its own ("MRR semantics require treating each vector result as a separate ranking system"). RRF is defined the same way. ## Fix Score each result list with its own ranks (`1 / (rank + K)`, summed across lists for rows found by more than one), then dedupe the concatenation by `_rowid`, attach `_relevance_score`, and sort. The `return_score` handling is unchanged. ## Tests `test_rrf_multivector_ranks_each_result_list` in `python/python/tests/test_rerankers.py`: - On `main`, it fails with `assert 0.015625 == 0.01639344262295082` (the top hit of list 2 got `1/64` instead of `1/61`). - With the fix, it passes, and so do the other tests in `test_rerankers.py` (16 passed, 12 skipped for missing API keys or models). - `ruff format --check` and `ruff check` are clean. The fix was found and written by an AI agent (Breken) and checked against the tests above.

A single blob over the byte cap could not be read through this method. ## Fix - Send at most 1024 row IDs per request and split batches further when the server reports the blob-byte cap, preserving input order and nulls. - Resolve one exact dataset version before multi-request reads. If an initial single request hits the byte cap, resolve the version before any successful split or Range read; use that version for every resulting request. - Read an individual oversized blob through the existing Range route. - Document the per-request caps and transparent handling in the Rust, Python, and TypeScript APIs and generated JS docs. ## Validation - Focused Rust `fetch_blobs` tests: 26 passed, including row-count, byte-cap, Range fallback, and exact-version assertions. - Rust clippy and formatting passed. - Focused Python blob tests: 13 passed; Ruff lint and formatting passed. - Node build, lint, docs generation, and focused `fetchBlobs` test passed.

Add composable DataFusion pair and retained-row relations so a host can use its existing SQL job and MV writer instead. `VectorQueryTable` binds a retained snapshot, selects all/first/random nonempty IVF scopes before dispatch, and exposes `DuplicatePairsExec` as its physical child. Pair queries can include segment, partition and snapshot columns and fetch a scalar application key for each endpoint without reading source vectors for scoring. The default primitive schema remains unchanged. `VectorDedupExec` consumes the pair stream, reuses the spillable greedy direct-representative selection, and scans retained original rows from that snapshot. A–B–C without A–C retains A and C. This query path has no durable partition receipts or writes; publication and failure belong to the enclosing SQL sink. Existing native MV APIs remain available. `BaseTableAdapter::vector_query_snapshot(None)` captures latest without changing a shared table handle's pin; `Some(version)` selects a retained version. A host can retain unbound SQL and resolve latest again for each refresh. Single-segment random sampling matches Sophon's `ivf_partition` SplitMix64 policy; multi-segment sampling ranks canonical nonempty scopes. Host integration and SQL syntax: https://github.com/lancedb/sophon/pull/8135. The host authorizes sources, binds named arguments, distributes the pair child, and uses its existing SQL Job Registry and atomic MV replacement. ## Validation All manual validation ran on an AWS r8i.8xlarge VM, not the developer laptop. - Focused Rust integration suite: 2 passed, including multiple segments/partitions, empty results, threshold boundaries, 8,193 rows per segment, deterministic sampling, mapped application IDs, and native-oracle pair equality. - Additional compacted stable/nonstable row-ID and blob test: 1 passed, including application-key mapping, null vectors, snapshot deletions and explicit/latest version capture. - Rust formatting and focused Clippy with warnings denied passed. - Dependent Sophon SQL-job E2E passes with two worker PEs: pairs, sampling, direct representatives, latest/fixed snapshot refreshes, and blob payloads. Killing a SQL worker after partial staging preserves the old MV; full rerun commits the complete replacement.

Later range reads resolved the latest version again, so an update or delete could make an opened handle fail. ## Fix For nonempty blobs, capture `x-lancedb-version` from the 206 size probe and include it on every later range request. Reject a nonempty probe without a valid version. Accept an empty-blob 416 probe with or without that header, because an empty handle makes no later data range request. The Python remote mock now covers both response shapes. ## Limitation A table dropped and recreated with the same name can reuse version numbers and row addresses. Version pinning does not identify the table itself, so an old handle can still return data from the recreated table. That identity case needs a separate fix. Callers that replace a table should discard its old blob handles. ## Validation - `cargo test --quiet --features remote -p lancedb --lib remote::table::blobs::tests` (24 passed) - Rebuilt the Python extension; `uv run --extra tests pytest python/tests/test_remote_db.py -q -k remote_blob` (6 passed) - `cargo clippy --quiet --features remote -p lancedb --lib --tests --examples` - `cargo fmt --all -- --check`, `ruff check .`, and `ruff format .` Fixes #4276 --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> --- python/python/tests/test_remote_db.py | 20 +++- rust/lancedb/src/remote/table.rs | 1 + rust/lancedb/src/remote/table/blobs.rs | 147 +++++++++++++++++++++++-- 3 files changed, 152 insertions(+), 16 deletions(-) diff --git a/python/python/tests/test_remote_db.py b/python/python/tests/test_remote_db.py index e32dbe8ca..cd4b78a1b 100644 --- a/python/python/tests/test_remote_db.py +++ b/python/python/tests/test_remote_db.py @@ -2403,11 +2403,16 @@ def blob_remote_table(*, server_version=Version("0.5.0")): elif request.path.startswith("/v1/table/test/blob/image/"): path = request.path.partition("?")[0] row_id = int(path.split("/")[-2]) - payload = {10: b"alpha", 20: None, 30: b"gamma"}[row_id] + payload = {10: b"alpha", 20: None, 30: b"gamma", 40: b""}[row_id] if payload is None: request.send_response(204) request.end_headers() return + if not payload: + request.send_response(416) + request.send_header("Content-Range", "bytes */0") + request.end_headers() + return byte_range = request.headers["Range"].removeprefix("bytes=") start_text, end_text = byte_range.split("-", maxsplit=1) start = int(start_text) @@ -2416,6 +2421,9 @@ def blob_remote_table(*, server_version=Version("0.5.0")): request.send_response(206) request.send_header("Content-Range", f"bytes {start}-{end}/{len(payload)}") request.send_header("Content-Length", str(len(chunk))) + request.send_header( + "x-lancedb-version", str(BLOB_DESCRIBE_RESPONSE["version"]) + ) request.end_headers() request.wfile.write(chunk) elif request.path == "/v1/table/test/query/": @@ -2459,17 +2467,21 @@ def test_remote_blob_columns_and_fetch(): def test_remote_blob_files_are_lazy_seekable_handles(): with blob_remote_table() as table: - files = table.fetch_blob_files("image", [10, 20, 30]) + files = table.fetch_blob_files("image", [10, 20, 30, 40]) - assert len(files) == 3 - alpha, null_row, gamma = files + assert len(files) == 4 + alpha, null_row, gamma, empty = files assert null_row is None assert alpha is not None assert gamma is not None + assert empty is not None assert alpha.size() == 5 assert alpha.read_range(1, 3) == b"lph" gamma.seek(2) assert gamma.read() == b"mma" + assert empty.size() == 0 + assert empty.read() == b"" + assert empty.read_range(0, 0) == b"" alpha.close() assert alpha.closed with pytest.raises(RuntimeError, match="already closed"): diff --git a/rust/lancedb/src/remote/table.rs b/rust/lancedb/src/remote/table.rs index 195c18ea5..238187931 100644 --- a/rust/lancedb/src/remote/table.rs +++ b/rust/lancedb/src/remote/table.rs @@ -5326,6 +5326,7 @@ mod tests { "bytes=0-0" => http::Response::builder() .status(206) .header(reqwest::header::CONTENT_RANGE, "bytes 0-0/10") + .header(VERSION_HEADER, "42") .body(b"0".to_vec()) .unwrap(), "bytes=0-" => http::Response::builder() diff --git a/rust/lancedb/src/remote/table/blobs.rs b/rust/lancedb/src/remote/table/blobs.rs index 29023eeed..07aeeae63 100644 --- a/rust/lancedb/src/remote/table/blobs.rs +++ b/rust/lancedb/src/remote/table/blobs.rs @@ -22,7 +22,8 @@ use crate::remote::client::{HttpSend, RequestResultExt, RestfulLanceDbClient}; use crate::table::BaseTable; use super::{ - FreshnessHeaders, FreshnessState, ReadSnapshot, RemoteTable, freshness_headers_snapshot, + FreshnessHeaders, FreshnessState, ReadSnapshot, RemoteTable, VERSION_HEADER, + freshness_headers_snapshot, }; // The Cloud route rejects larger row-id lists.

In a mixed bytes and URI batch, Arrow inferred a binary column and encoded the URI as inline bytes; dict and `lance.Blob` values could fail conversion. ## Fix Build blob v2 columns from the original Python values using the target field's storage type before converting the rest of each row. This preserves inline bytes, external URIs, descriptor dictionaries, blob objects, and nulls for `add`, `merge_insert`, and `create_table`. ## Validation - `python/tests/test_blob.py`: 76 passed, 1 skipped. - Python project Ruff check passed. - Repository-wide Ruff check still reports 29 existing findings in `ci/` files outside this change.

2026 20:11:34 +0500 Subject: [PATCH 26/38] fix(rust): list indices when an FTS index's files are missing (#4330) Fixes #4250. `list_indices()` reads each FTS index's files to fill `index_details`. When those files were missing, the error failed the whole call, so the caller could not list any index, including the damaged one it needs to rebuild. Scalar indexes were not affected because their listing reads only the manifest. Now a failed read logs a warning and leaves that index's `index_details` as `None`. The other fields still come from the manifest, and `tokenize()` already returns a clear error when an FTS index has no details. The new test `test_list_indices_with_missing_fts_index_files` creates an FTS index and a BTree index, deletes the FTS index directory, and reopens the table. It then checks that both indexes are still listed. Without the change, it fails with the same `Not found` error as the issue. --- rust/lancedb/src/table.rs | 15 ++++++++- rust/lancedb/src/table/create_index.rs | 44 ++++++++++++++++++++++++++ 2 files changed, 58 insertions(+), 1 deletion(-) diff --git a/rust/lancedb/src/table.rs b/rust/lancedb/src/table.rs index f6455b290..251baad99 100644 --- a/rust/lancedb/src/table.rs +++ b/rust/lancedb/src/table.rs @@ -3791,7 +3791,20 @@ impl BaseTable for NativeTable { let Some(segment) = segments.first() else { continue; }; - let params = load_segment_params(&dataset, segment).await?; + // The listing itself only needs the manifest.

Lance's new combined-fields FTS query variant (introduced by v13.0.0-beta.17) is handled the same way as in #4336: the remote capability check and Rust/Node bindings accept it, with a regression test for the remote request payload, and the Python conversion reports that this query type is not yet supported. This PR supersedes #4336. --- Cargo.lock | 89 ++++++++++++++++---------------- Cargo.toml | 28 +++++----- java/pom.xml | 2 +- nodejs/src/query.rs | 1 + python/src/query.rs | 3 ++

<74999164+BilalAtique@users.noreply.github.com> Date: Tue, 29 Sep 2026 21:32:30 +0500 Subject: [PATCH 28/38] feat(node): expose seek, tell, bounded read, readRanges and close on BlobFile (#4348) Closes #4300. The TypeScript `BlobFile` only had `size()`, `read()` and `readRange()`, while the Rust `BlobFile` behind it also has `seek`, `tell`, `read_up_to`, `read_ranges` and `close`. This exposes those on the Node binding: - `read(maxBytes?)` reads at most `maxBytes` from the cursor (Rust `read_up_to`). Without the argument it reads to the end, as before. - `readRanges([{ start, end }, ...])` reads several half-open ranges and returns one buffer per range, in order. Like `readRange`, it does not move the cursor. - `seek(position)` and `tell()` move and report the cursor. - `close()` releases the handle, and `isClosed()` reports it. Every read, `seek` and `tell` after `close()` fails with "blob file is already closed". A second `close()` does nothing. The binding keeps its own `closed` flag, the same way the Python `BlobFile` does. Offsets and lengths are `bigint`, like `readRange` and `size()`. `BlobRange` is exported as a type. The new tests in `table.test.ts` cover chunked reads with `read(maxBytes)`, `seek` and `tell`, a negative seek position, `readRanges` order and cursor, a `readRanges` end past the blob size, and reads after `close()`. The Node docs under `docs/src/js` are regenerated with `pnpm run docs`. I left the `ReadableStream`/async iterator idea from the issue out of this PR. The AbortSignal work in #4288 touches the same methods, so it can follow on top of this. --- docs/src/js/classes/BlobFile.md | 95 +++++++++++++++++++++++++-- docs/src/js/globals.md | 1 + docs/src/js/type-aliases/BlobRange.md | 27 ++++++++ nodejs/__test__/table.test.ts | 68 +++++++++++++++++++ nodejs/lancedb/blob.ts | 50 ++++++++++++-- nodejs/lancedb/index.ts | 2 +- nodejs/src/blob.rs | 79 +++++++++++++++++++++- 7 files changed, 310 insertions(+), 12 deletions(-) create mode 100644 docs/src/js/type-aliases/BlobRange.md diff --git a/docs/src/js/classes/BlobFile.md b/docs/src/js/classes/BlobFile.md index 84a596d1a..ee9f9ad28 100644 --- a/docs/src/js/classes/BlobFile.md +++ b/docs/src/js/classes/BlobFile.md @@ -10,16 +10,50 @@ A lazy handle to blob bytes.

Mypy's suggested `Vector[...]` spelling also cannot represent a dimension computed at runtime and fails because `Vector` is a function. `VectorField` already carries the embedding function and its dimension, but schema conversion previously ignored that metadata for a statically valid `list[float]` annotation. The runtime factory remains available for dimension-constrained Pydantic validation. Embedding-backed models that require mypy compatibility can now use `list[float] = embedding.VectorField()`; LanceDB derives the same nullable fixed-size float32 Arrow type from the field metadata. ## Validation - `cd python && uv run --extra tests pytest python/tests/test_pydantic.py -q` (23 passed) - focused mypy check reproducing the original error and accepting the new `LanceModel` declaration - isolated schema checks with Pydantic 1.10.24 and 2.11.7 - `ruff format .` - `ruff check .` Fixes #1982 Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> --- python/python/lancedb/embeddings/base.py | 6 +++- python/python/lancedb/pydantic.py | 39 ++++++++++++++++++++++++ python/python/tests/test_pydantic.py | 20 ++++++++++++ 3 files changed, 64 insertions(+), 1 deletion(-) diff --git a/python/python/lancedb/embeddings/base.py b/python/python/lancedb/embeddings/base.py index 149b9c089..fbe43860d 100644 --- a/python/python/lancedb/embeddings/base.py +++ b/python/python/lancedb/embeddings/base.py @@ -182,7 +182,11 @@ class EmbeddingFunction(BaseModel, ABC): def VectorField(self, **kwargs): """ Creates a pydantic Field that can automatically annotate - the target vector column for this embedding function + the target vector column for this embedding function. + + The field can be annotated as ``list[float]`` for compatibility with + static type checkers.

Regression tests cover createTable and add with Arrow 15–18 and adding a LargeBinary Arrow column to a blob table. ## Validation - Confirmed the new table test failed before the fix with `Unrecognized type id in schema: 20` on all four Arrow versions. - The table, sanitizer, and Arrow Jest suites passed: 604 tests. - `pnpm lint`, `pnpm build`, and `pnpm run docs` passed.

Blob reads in Node can now be cancelled. `BlobFile.read`, `readRange` and `readRanges`, and `Table.fetchBlobs` and `fetchBlobFiles` take an optional `{ signal?: AbortSignal }` (new `BlobReadOptions` type). When the signal aborts, the call rejects with `signal.reason` (an `AbortError` unless the caller gave a reason) and the native future is dropped, so the read stops instead of running to completion. A signal that is already aborted rejects before any read starts. How it works: - On the Rust side, these five methods are now sync `#[napi]` methods that return `env.spawn_future(...)`. The future is wrapped in `futures::future::abortable`, and the abort handle is registered with napi's `AbortSignal::on_abort`. napi's `AbortSignal` is `Rc`-based, so it can't be an argument of an `async fn`, which is why the methods changed shape. The TypeScript signatures are unchanged apart from the new optional argument. - napi-rs installs its own `onabort` on the signal it receives, which would overwrite a handler the caller set. So the TypeScript wrapper passes a private `AbortController` signal to the native call for each request, forwards the caller's abort to it with `addEventListener(..., { once: true })`, and removes the listener when the call settles. Tests in `table.test.ts`: - an already aborted signal rejects on all five methods, and the handle still reads afterwards - a custom abort reason is what the call rejects with - a read with a signal that never aborts returns normally and leaves no `abort` listener on the signal - aborting a 32 MiB `readRange` right after it starts rejects with `AbortError`, and the same handle reads again afterwards The Node docs under `docs/src/js` are regenerated. I didn't add a test for where the `read()` cursor ends up after a mid-flight abort on a local table. The remote `BlobFile` documents that a cancelled read leaves the cursor unchanged, but I haven't confirmed the same for the native Lance handle, so the docs don't claim it. --- docs/src/js/classes/BlobFile.md | 15 ++- docs/src/js/classes/Table.md | 14 ++- docs/src/js/globals.md | 1 + docs/src/js/type-aliases/BlobReadOptions.md | 24 +++++ nodejs/__test__/table.test.ts | 75 ++++++++++++++ nodejs/lancedb/blob.ts | 60 ++++++++++-- nodejs/lancedb/index.ts | 2 +- nodejs/lancedb/table.ts | 15 ++- nodejs/src/blob.rs | 102 ++++++++++++++------ nodejs/src/table.rs | 49 ++++++---- 10 files changed, 293 insertions(+), 64 deletions(-) create mode 100644 docs/src/js/type-aliases/BlobReadOptions.md diff --git a/docs/src/js/classes/BlobFile.md b/docs/src/js/classes/BlobFile.md index ee9f9ad28..ee012be25 100644 --- a/docs/src/js/classes/BlobFile.md +++ b/docs/src/js/classes/BlobFile.md @@ -42,7 +42,7 @@ Returns true after [BlobFile.close](BlobFile.md#close). ### read() ```ts -read(maxBytes?): Promise +read(maxBytes?, options?): Promise ``` Reads from the cursor and advances the cursor. @@ -55,6 +55,8 @@ otherwise.

The namespace is addressed in the route identifier (`/v1/function/analytics$features$embed/describe`, `/v1/namespace/analytics$features/function/list`); no body carries it. `FunctionVersion` and `FunctionVersionRef` name their Function **by parts** — a short `name` plus `namespace_path` — the same shape as `SecretReference`, so a returned version reopens from its own fields: ```python fv = db.create_function(embed, namespace_path=["analytics", "features"]) fv.name, fv.namespace_path # "embed", ("analytics", "features") db.get_function(fv.name, version=fv.version, namespace_path=list(fv.namespace_path)) ``` An empty path is omitted from the wire, so root documents keep their shape. `namespace_path` is passed straight to the binding, so a bare string (`namespace_path="prod"`) is a `TypeError` rather than four one-character segments; segments are checked for addressability before a request is built. The binding and application allow-lists now share one field list, `FUNCTION_VERSION_REF_FIELDS`, which admits `namespace_path` — without it a namespaced binding or application read as coming from a newer contract. ## Service side The Sophon half serves and persists FunctionVersion / FunctionVersionRef documents in this split form, keeping the joined id as its internal catalog key. It lands in sophon with the submodule bump. ## Tests - Rust: every Function verb addresses a namespace in the path; an unaddressable segment never reaches the transport; `FunctionVersion` round-trips a namespace and `reference()` carries it; a namespaced binding and application are known shapes. - Python: sync and async verbs address the namespace; a created Function reopens from its own `name`/`namespace_path`; a bare-string path is refused before any request. Draft: compiles, `cargo fmt --check` and clippy `-D warnings` clean; lancedb lib Function tests (116) and `first_class_function_slice2` pass on this base. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 5.5 --- python/python/lancedb/_lancedb.pyi | 18 +- python/python/lancedb/db.py | 154 ++++++++++++++---- python/python/lancedb/functions.py | 11 +- python/python/lancedb/remote/db.py | 55 ++++++- .../tests/test_first_class_function_slice1.py | 23 +++ .../tests/test_first_class_function_slice2.py | 118 +++++++++++++- python/src/connection.rs | 32 +++- rust/lancedb/src/connection.rs | 29 +++- rust/lancedb/src/database.rs | 23 ++- rust/lancedb/src/function.rs | 83 ++++++++-- rust/lancedb/src/remote/db.rs | 136 +++++++++++++--- rust/lancedb/src/table/computed_columns.rs | 22 ++- .../tests/first_class_function_slice2.rs | 9 +- 13 files changed, 602 insertions(+), 111 deletions(-) diff --git a/python/python/lancedb/_lancedb.pyi b/python/python/lancedb/_lancedb.pyi index cf63d7a9b..176e57ac3 100644 --- a/python/python/lancedb/_lancedb.pyi +++ b/python/python/lancedb/_lancedb.pyi @@ -149,12 +149,20 @@ class Connection(object): limit: Optional[int], ) -> list[str]: ... # Deprecated: Use list_tables instead async def open_job(self, job_id: str) -> Job: ... - async def create_function_async(self, request_json: str) -> Job: ... - async def get_function(self, name: str, version: str) -> str: ... - async def list_functions(self) -> List[str]: ... - async def drop_function(self, name: str, version: str) -> bool: ... + async def create_function_async( + self, request_json: str, namespace_path: Optional[List[str]] = None + ) -> Job: ... + async def get_function( + self, name: str, version: str, namespace_path: Optional[List[str]] = None + ) -> str: ... + async def list_functions( + self, namespace_path: Optional[List[str]] = None + ) -> List[str]: ... + async def drop_function( + self, name: str, version: str, namespace_path: Optional[List[str]] = None + ) -> bool: ... async def drop_function_async( - self, name: str, version: str + self, name: str, version: str, namespace_path: Optional[List[str]] = None ) -> Tuple[bool, Job]: ... async def create_secret( self, name: str, value: str, namespace_path: Optional[List[str]] = None diff --git a/python/python/lancedb/db.py b/python/python/lancedb/db.py index 490987c3c..60e1780f0 100644 --- a/python/python/lancedb/db.py +++ b/python/python/lancedb/db.py @@ -784,6 +784,7 @@ class DBConnection(EnforceOverrides): definition: UdfDefinition, *, secrets: Optional[Sequence[EnvVarSecret]] = None, + namespace_path: Optional[List[str]] = None, ) -> FunctionVersion: """Build and register a scalar Python UDF, then return its version. @@ -800,6 +801,9 @@ class DBConnection(EnforceOverrides): Function needs, each naming a Secret and the environment variable its value arrives in.

Removes a redundant `pub(crate)` declaration in the private Node.js blob module to satisfy the required Clippy check. Validation: `cargo clippy --quiet --workspace --tests --all-features -- -D warnings`, `cargo fmt --all --quiet`, `pnpm build`, and `pnpm test __test__/blob.test.ts --runInBand` (26 tests passed) in

A named set is checked here, where the caller can be told which names exist; an index of a kind the MemWAL cannot mirror fails a named set and is skipped by an unnamed one. **A newly created index reaches a writer that is already open.** lancedb caches a `ShardWriter` per shard and reuses it, so `create_index` installs the current set on the cached writer. A failure there is reported rather than propagated: the index is committed durably by then, and the writer this process holds may be fenced or poisoned, which is no reason to fail creating an index. **A table carries one spec.** `set_lsm_write_spec` fails while one is installed and names `unset_lsm_write_spec` in the error, because the generations already written were homed under that spec. Accepting a repeat that changed only the maintained set would hand a caller who also passed a different sharding a success that changed nothing they asked for. **The read path asks what is actually carried.** An unnamed set leaves the stored list empty, so the list alone cannot decide whether an index is maintained. The read asks the spec *and* every resident MemTable whether it carries the index, so a MemTable built before the index joined the set refuses the read rather than answering without its rows. Both spec routes report an unnamed set as `null` rather than `[]`: maintain whatever the table gains, and maintain nothing, are different settings. ## Known gap The guard above covers resident MemTables. Once a writer flushes and closes none is resident, so a retained generation written before the index existed still gets an indexed read that omits its rows. This window is **wider than on main**: a set resolved at install time excluded an index created later, so the read was refused; an intent includes it, and the refusal only holds while a MemTable is resident. Closing it needs the generation's own coverage, which this layer cannot see — its snapshot carries a generation and a path — so it belongs in lance's scanner or flush path. ## Testing `cargo nextest run -p lancedb --lib --features remote` — **1479 passed, 3 skipped**. `cargo fmt --all --check`, and `cargo clippy --features remote --lib --tests --examples -- -D warnings`, both clean. Covered: the round trip of an unnamed set, a set over an installed spec refused, a spec replaced through unset, a read refused while a resident MemTable predates the index, and an index created mid-write reaching the open writer. Two Python binding tests move with the semantics: an unnamed set now reads back as `None` rather than the list it resolves to, and the refusal is matched on `already set`. Neither was run locally — no Python build here — so CI is the check on them. --- python/python/tests/test_lsm_write_spec.py | 14 +- rust/lancedb/src/table.rs | 102 +++++++----- rust/lancedb/src/table/create_index.rs | 6 + rust/lancedb/src/table/merge.rs | 183 +++++++++++++++++++++ rust/lancedb/src/table/merge/lsm.rs | 136 ++++++++------- rust/lancedb/src/table/query/lsm.rs | 112 +++++++++---- 6 files changed, 421 insertions(+), 132 deletions(-) diff --git a/python/python/tests/test_lsm_write_spec.py b/python/python/tests/test_lsm_write_spec.py index d43cb7532..ac767ea31 100644 --- a/python/python/tests/test_lsm_write_spec.py +++ b/python/python/tests/test_lsm_write_spec.py @@ -52,9 +52,9 @@ def test_set_lsm_write_spec_validates(tmp_path): with pytest.raises(Exception, match="num_buckets"): table.set_lsm_write_spec(LsmWriteSpec.bucket("id", 1025)) - # Happy path then mutation rejected. + # Happy path, then a set over the installed spec is refused. table.set_lsm_write_spec(LsmWriteSpec.bucket("id", 4)) - with pytest.raises(Exception, match="mutation"): + with pytest.raises(Exception, match="already set"): table.set_lsm_write_spec(LsmWriteSpec.bucket("id", 8)) @@ -176,18 +176,18 @@ def test_get_lsm_write_spec(tmp_path): table.unset_lsm_write_spec() assert table.get_lsm_write_spec() is None - # Identity round-trips (column recovered from the schema).

Updates `napi` from 3.12.2 to 3.12.5
Release notes

Sourced from napi's releases.

napi-v3.12.5

Fixed

  • fatal_exception noop in optimized builds (#3509)

napi-v3.12.4

Security

  • Object::unwrap and Object::remove_wrapped (and the deprecated Env::unwrap / Env::drop_wrapped) read a TypeId out of a payload that is not a TaggedObject, giving a heap out-of-bounds read and a JavaScript-forgeable out-of-bounds write; payload provenance is now validated before dereferencing. See GHSA-rhpj-pggq-896v, fixed in #3506.
  • The serde deserializer reached unreachable!() on ordinary JavaScript values and aborted the process instead of returning an error. See GHSA-f334-75xc-qxv3, fixed in #3507.
  • ArrayBuffer::from_external, TypedArraySlice::from_external and Uint8ClampedSlice::from_external (plus the compat-mode Env::create_arraybuffer_with_borrowed_data) built their slice from freed memory on runtimes without external buffers. See GHSA-32mm-r9wp-hrvc, fixed in #3503.

Fixed

  • (napi) return errors from the serde deserializer for unexpected JS value shapes (#3507)
  • (napi) validate wrapped payload provenance in Object::unwrap/remove_wrapped (#3506)
  • (napi) point from_external slices at the engine-owned copy after finalize reclaims the source (#3503)

napi-v3.12.3

Fixed

  • CurrentThread waker-stack deadlocks and threadless-wasm Buffer detachment (#3489)

I was just looking into this myself. I started with your PR and added: - make arrow 21 the default - widen the peer range to <22 so if they release 21.3 that'll be included - have to do skipLibCheck in tsconfig.json, because of flatbuffers 25 which needs TypeScript 5.7 - fix override in Symbol.hasInstance - support new types in Arrow 20-21 (LargeList, Utf8View, BinaryView, IntervalMonthDayNano) - arrow-compat job in nodejs.yml that runs tests with arrow 19 and 20 (adds 2 sec) - put the list of arrow types in one place - update NODEJS_THIRD_PARTY_LICENSES.md - regenerated typescript docs (sorry about reorderings, one time cost) - reformat arrow.test.ts (sorry, almost all whitespace, thanks to biome. git diff -w shows 110 lines edited) - fixed Sliced Utf8View / BinaryView serialization error, by just converting them to Utf8 and Binary (as our rust code would anyway) --------- Co-authored-by: Vincent Koc Co-authored-by: Claude Fable 5.1 --- .github/workflows/nodejs.yml | 65 + docs/src/js/classes/AutoQuery.md | 2 +- docs/src/js/classes/Query.md | 2 +- docs/src/js/classes/QueryBase.md | 2 +- docs/src/js/classes/Table.md | 2 +- docs/src/js/classes/TakeQuery.md | 2 +- docs/src/js/classes/VectorQuery.md | 2 +- docs/src/js/globals.md | 1 + docs/src/js/interfaces/CherryPickResult.md | 6 +- .../src/js/interfaces/DropNamespaceOptions.md | 2 +- .../embedding/classes/EmbeddingFunction.md | 4 +- .../classes/TextEmbeddingFunction.md | 4 +- docs/src/js/type-aliases/DataTypeLike.md | 18 + nodejs/NODEJS_THIRD_PARTY_LICENSES.md | 8 + nodejs/__test__/arrow.test.ts | 2871 ++++++++--------- nodejs/__test__/arrow_versions.ts | 39 + nodejs/__test__/registry.test.ts | 13 +- nodejs/__test__/sanitize.test.ts | 114 +- nodejs/__test__/table.test.ts | 129 +- nodejs/lancedb/arrow.ts | 87 +- nodejs/lancedb/index.ts | 1 + nodejs/lancedb/sanitize.ts | 146 +- nodejs/package.json | 6 +- nodejs/pnpm-lock.yaml | 98 +- nodejs/tsconfig.json | 5 +- 25 files changed, 2110 insertions(+), 1519 deletions(-) create mode 100644 docs/src/js/type-aliases/DataTypeLike.md create mode 100644 nodejs/__test__/arrow_versions.ts diff --git a/.github/workflows/nodejs.yml b/.github/workflows/nodejs.yml index 98acccf02..2e290166e 100644 --- a/.github/workflows/nodejs.yml +++ b/.github/workflows/nodejs.yml @@ -164,6 +164,71 @@ jobs: python ci/mock_openai.py & cd nodejs/examples node_modules/.bin/jest --testEnvironment jest-environment-node-single-context --verbose + arrow-compat: + # The main jobs resolve `apache-arrow` to the version pinned in + # devDependencies (the newest supported release).
