From 706a9c327fb324e7961620cf1e159fe8c15f7fab Mon Sep 17 00:00:00 2001 From: Dan Rammer Date: Fri, 7 Aug 2026 14:50:22 -0500 Subject: [PATCH 01/22] feat: infer maintained indexes when an LsmWriteSpec omits them (#3748) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## What `LsmWriteSpec::maintained_indexes` becomes `Option>`: | value | meaning | |---|---| | `None` (new default) | every index the MemWAL supports, resolved when the spec is installed | | `Some([])` | maintain nothing β€” a scan/filter-only WAL table | | `Some([..])` | exactly these, taken verbatim | `with_maintained_indexes` keeps its signature; `with_no_maintained_indexes()` is new. Surfaced through the remote path (null on the wire), Python, and Node. ## Why Callers had to state the maintained set by hand every time, which is both tedious and easy to get wrong β€” the common case is "maintain what I already built." Resolution filters on `IndexConfig::is_memwal_maintainable`, delegating to lance's `is_maintainable_index_type`. This is load-bearing rather than cosmetic: lance does **not** skip an index type its memtable cannot build, it errors when the shard writer opens, so sweeping up a bitmap index would fail every memtable claim and leave the table unwritable. The inferred set excludes those, and an explicit list naming one is now rejected at spec time instead of at claim time. ## Behavior change A freshly constructed spec used to maintain **nothing**; it now maintains **everything supported**. This flipped because napi collapses `undefined` and `null` to `None`, so TypeScript cannot express "absent means nothing, null means all" β€” any other choice makes the bindings disagree with the wire. The error direction also favors it: an unwanted maintained index costs memory, while a silently unmaintained one degrades FTS to an unscored scan. Three existing tests encoded the old default and are updated rather than worked around. ## Caveat The resolved set is a snapshot, not a subscription. An index created after the spec is installed is not maintained until the spec is unset and set again. `get_lsm_write_spec` therefore always reports a concrete list β€” `None` never round-trips. ## Dependency Needs a lance release carrying `is_maintainable_index_type` (lance-format/lance#8095) before this builds against the pinned tag. Draft until then. ## Testing 38 Rust LSM tests and 10 Python tests pass against a local lance build, including new coverage that a bitmap index is excluded from inference and rejected when named, and that `[]` stays distinguishable from null on the wire. πŸ€– Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5 (1M context) --- docs/src/js/classes/Table.md | 12 +- docs/src/js/interfaces/LsmWriteSpec.md | 4 +- nodejs/lancedb/table.ts | 18 +- nodejs/src/table.rs | 12 +- python/python/lancedb/_lancedb.pyi | 11 +- python/python/lancedb/table.py | 13 +- python/python/tests/test_lsm_write_spec.py | 15 +- python/python/tests/test_merge_insert_lsm.py | 4 +- python/src/table.rs | 46 +++-- rust/lancedb/src/remote/table.rs | 30 ++- rust/lancedb/src/table.rs | 202 +++++++++++++++---- rust/lancedb/src/table/merge.rs | 4 +- rust/lancedb/src/table/merge/lsm.rs | 82 +++++++- 13 files changed, 360 insertions(+), 93 deletions(-) diff --git a/docs/src/js/classes/Table.md b/docs/src/js/classes/Table.md index 11fca32d0..3fa3b08db 100644 --- a/docs/src/js/classes/Table.md +++ b/docs/src/js/classes/Table.md @@ -431,9 +431,10 @@ Read the [LsmWriteSpec](../interfaces/LsmWriteSpec.md) currently installed on th Resolves to `undefined` when the MemWAL LSM write path is not enabled (no spec has been set, or it was removed with [Table#unsetLsmWriteSpec](Table.md#unsetlsmwritespec)). -The returned spec β€” including its `maintainedIndexes` and -`writerConfigDefaults` β€” mirrors what was passed to -[Table#setLsmWriteSpec](Table.md#setlsmwritespec). +The returned spec mirrors what was passed to +[Table#setLsmWriteSpec](Table.md#setlsmwritespec), except that `maintainedIndexes` always +reports the concrete list resolved when the spec was set β€” `undefined` +never round-trips. #### Returns @@ -806,6 +807,11 @@ All variants require the table to have an unenforced primary key ([Table#setUnenforcedPrimaryKey](Table.md#setunenforcedprimarykey)); bucket sharding additionally requires it to be the single column being bucketed. +Omitting `maintainedIndexes` maintains every index on the table, resolved +here, failing if one cannot be maintained β€” name them to install anyway. +Naming them pins an exact set, and a still-building index is rejected +rather than quietly omitted. + #### Parameters * **spec**: [`LsmWriteSpec`](../interfaces/LsmWriteSpec.md) diff --git a/docs/src/js/interfaces/LsmWriteSpec.md b/docs/src/js/interfaces/LsmWriteSpec.md index 8a588df6a..f2ae91186 100644 --- a/docs/src/js/interfaces/LsmWriteSpec.md +++ b/docs/src/js/interfaces/LsmWriteSpec.md @@ -34,7 +34,9 @@ Bucket and identity variants: the sharding column. optional maintainedIndexes: string[]; ``` -Names of indexes the MemWAL should keep up to date during writes. +Indexes the MemWAL keeps up to date.

The module-level `is_valid_url()` a few lines above does it correctly (`urlparse(text)`), which is why this reads as a typo rather than intentional. Fixed to `urlparse(str(image))` β€” `str()` is needed because `urlparse()` only accepts `str`/`bytes` and raises a different `AttributeError` on a raw `Path`. ## Testing Added `test_jina_generate_image_input_dict_local_path`, which fails with the original `AttributeError` before the fix and passes after, covering both a `str` path and a `pathlib.Path`. Verified locally (built the Rust extension, ran redβ†’green, then the full `test_embeddings.py` file: 15 passed / 8 skipped, no regressions) and with `ruff check`/`ruff format`. --- Disclosure: this PR was drafted with AI assistance (Claude); I reviewed, tested, and take responsibility for the change. --------- Co-authored-by: Claude Opus 4.8 --- python/python/lancedb/embeddings/jinaai.py | 7 ++++--- python/python/tests/test_embeddings.py | 20 ++++++++++++++++++++ 2 files changed, 24 insertions(+), 3 deletions(-) diff --git a/python/python/lancedb/embeddings/jinaai.py b/python/python/lancedb/embeddings/jinaai.py index 9656f041f..f6ab601b3 100644 --- a/python/python/lancedb/embeddings/jinaai.py +++ b/python/python/lancedb/embeddings/jinaai.py @@ -87,12 +87,13 @@ class JinaEmbeddings(EmbeddingFunction): if isinstance(image, bytes): image_dict = {"image": base64.b64encode(image).decode("utf-8")} elif isinstance(image, (str, Path)): - parsed = urlparse.urlparse(image) - # TODO handle drive letter on windows. + parsed = urlparse(str(image)) PIL_Image = attempt_import_or_raise("PIL.Image", "pillow") if parsed.scheme == "file": pil_image = PIL_Image.open(parsed.path) - elif parsed.scheme == "": + elif parsed.scheme == "" or (os.name == "nt" and len(parsed.scheme) == 1): + # A Windows drive letter parses as a one-character scheme + # ("C:\\img.png" -> scheme="c"), so treat it as a local path. pil_image = PIL_Image.open(image if os.name == "nt" else parsed.path) elif parsed.scheme.startswith("http"): pil_image = PIL_Image.open(io.BytesIO(url_retrieve(image))) diff --git a/python/python/tests/test_embeddings.py b/python/python/tests/test_embeddings.py index 678270f19..9850669eb 100644 --- a/python/python/tests/test_embeddings.py +++ b/python/python/tests/test_embeddings.py @@ -631,3 +631,23 @@ def test_url_retrieve_downloads_image(): image_bytes = url_retrieve(image_url) img = Image.open(io.BytesIO(image_bytes)) assert img.size[0] > 0 and img.size[1] > 0 + + +def test_jina_generate_image_input_dict_local_path(tmp_path): + """ + JinaEmbeddings._generate_image_input_dict must accept a local image path + (str or Path), not just bytes.

It also dropped the separate dictionary vector payload and did not preserve identity shared by dictionary schema types, vector wrappers, or growing dictionary chunks. ## Fix Recursively sanitize nested Arrow data types and child data. Use one table-scoped sanitization context to rebuild and memoize source type objects, dictionary vectors, and Data nodes in the local Arrow realm, preserving all identities required by Arrow IPC. Add Arrow 15 through 18 regressions for list serialization, ordinary dictionaries, dictionaries shared across fields and batches, growing dictionaries, and IPC round trips. ## Validation - pnpm test __test__/arrow.test.ts --runInBand (188 passed) - pnpm lint - pnpm build - pnpm test --runInBand (706 passed, 5 skipped) - pnpm run docs Fixes #2256 --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> --- nodejs/__test__/arrow.test.ts | 115 +++++++++++++++++++ nodejs/lancedb/sanitize.ts | 203 +++++++++++++++++++++++++++++----- 2 files changed, 289 insertions(+), 29 deletions(-) diff --git a/nodejs/__test__/arrow.test.ts b/nodejs/__test__/arrow.test.ts index c05849cb9..29030d4f8 100644 --- a/nodejs/__test__/arrow.test.ts +++ b/nodejs/__test__/arrow.test.ts @@ -6,7 +6,9 @@ import * as arrow17 from "apache-arrow-17";

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary `opendal 0.58.1` (the version pulled in transitively via Lance) already ships `goosefs-sdk 0.1.9`, which includes the upstream fix for the 0.1.6 compile break. The explicit version pin that lancedb has been carrying since the GooseFS feature was introduced is therefore no longer necessary and is now redundant work to maintain. ## Changes - Remove the direct `goosefs-sdk` dependency from `rust/lancedb/Cargo.toml` (it was pinned to `=0.1.9` with a comment referencing the 0.1.6 compile break). - Remove the `dep:goosefs-sdk` entry from the `goosefs` cargo feature, since no source file in lancedb imports the crate directly. - Refresh `Cargo.lock`; `goosefs-sdk 0.1.9` now resolves transitively through `lance` β†’ `opendal 0.58.1`. ## Verification - `cargo fmt --all` β€” clean - `cargo check --features remote,goosefs --tests --examples` β€” passes - `Cargo.lock` confirms `goosefs-sdk 0.1.9` is still resolved (now transitively), so the `goosefs` feature continues to enable the same set of Lance/IOPaths as before. ## Backwards compatibility No public API changes. The `goosefs` cargo feature still activates `lance/goosefs`, `lance-io/goosefs`, and `lance-namespace-impls/dir-goosefs`, and the same `goosefs-sdk 0.1.9` version is selected by the resolver. --- Cargo.lock | 1 - rust/lancedb/Cargo.toml | 3 --- 2 files changed, 4 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 20f20a0ac..ec6b7cbfb 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -5447,7 +5447,6 @@ dependencies = [ "datafusion-physical-plan", "datafusion-sql", "futures", - "goosefs-sdk", "half", "hf-hub", "http 1.5.0", diff --git a/rust/lancedb/Cargo.toml b/rust/lancedb/Cargo.toml index 2dbd9d895..e33b86b12 100644 --- a/rust/lancedb/Cargo.toml +++ b/rust/lancedb/Cargo.toml @@ -49,8 +49,6 @@ lance-namespace = { workspace = true } lance-namespace-impls = { workspace = true } metrics = { workspace = true, optional = true } metrics-util = { workspace = true, optional = true } -# Pin the GooseFS SDK to the version required by Lance's OpenDAL dependency. -goosefs-sdk = { version = "=0.1.9", optional = true } moka = { workspace = true } pin-project = { workspace = true } tokio = { version = "1.23", features = ["rt-multi-thread", "sync"] } @@ -136,7 +134,6 @@ azure = [ ] cos = ["lance/tencent", "lance-io/tencent"] goosefs = [ - "dep:goosefs-sdk", "lance/goosefs", "lance-io/goosefs", "lance-namespace-impls/dir-goosefs", From 5acce6782e456f5f33a436a247290c4f796264f1 Mon Sep 17 00:00:00 2001 From: Xuanwo Date: Mon, 10 Aug 2026 15:08:36 +0800 Subject: [PATCH 07/22] ci(docs): report link checker failures through issues (#3909) --- .github/workflows/docs-link-check.yml | 119 +++++++++++++++----------- 1 file changed, 70 insertions(+), 49 deletions(-) diff --git a/.github/workflows/docs-link-check.yml b/.github/workflows/docs-link-check.yml index 0e22100eb..1286819bc 100644 --- a/.github/workflows/docs-link-check.yml +++ b/.github/workflows/docs-link-check.yml @@ -36,7 +36,9 @@ jobs: permissions: contents: read outputs: + checker_outcome: ${{ steps.lychee.outcome }} exit_code: ${{ steps.lychee.outputs.exit_code }} + status: ${{ steps.validate.outputs.status }} steps: - name: Checkout uses: actions/checkout@v6 @@ -50,6 +52,7 @@ jobs: - name: Check links id: lychee + continue-on-error: true uses: lycheeverse/lychee-action@e7477775783ea5526144ba13e8db5eec57747ce8 # v2.9.0 with: # Restricted to http(s) on purpose.

Today any transform exception aborts iteration, and there is no way to skip invalid rows during loading. ## Solution New `on_transform_error` parameter on `StreamingDataset`: - `"raise"` (default, matches current behavior and the convention in tf.data / WebDataset / Ray Data) - `"skip"` β€” drop the failing rows and continue - `"warn"` β€” like skip, plus a logged warning per failing batch - a WebDataset-style callable `handler(exc) -> bool`, so users can skip only expected error types Key design points: - **Row-granular skipping**: when a batch fails, the transform is re-run on single-row slices so only the rows that actually fail are dropped (avoids Ray-style whole-block loss). Skips are counted in a new `rows_skipped` property. - **No crash on uneven skips**: the round-robin loop now ends the epoch at the last cycle where every split still has a row, instead of hitting `IndexError` when a split runs dry early. - **Exact resumability under skips**: checkpoints are now position-based. `state_dict` gains `positions_consumed_per_split` (exact for owned splits), and a new `merge_state_dicts` static method combines per-rank states via elementwise max for elastic resume across topology changes. Old checkpoints without the new key still load. Positions equal sample counts when nothing is skipped, so existing behavior is unchanged. - **Guardrail**: transforms returning the wrong number of rows now raise a clear `ValueError` instead of silently corrupting split accounting. ### Answers to the issue's open questions - *Can we do this?* Yes β€” all transforms funnel through one guarded call in the Stage 2 pipeline. - *What do other libraries do?* tf.data `ignore_errors()`, WebDataset `handler=`, Ray `max_errored_blocks`; MosaicML StreamingDataset offers nothing (skipping conflicts with its determinism model). This design follows the common conventions: raise by default, opt-in skipping, count/log drops. - *Error handling or pre-filtering?* Both: the existing `filter=` remains the recommended tool for predictable bad data (splits are built post-filter, so all guarantees hold β€” now documented); `on_transform_error` covers failures not expressible as a predicate. - *Impact on splits / elastic determinism?* Per-split sample sequences stay deterministic (skips are data-dependent, not topology-dependent). With unequal bad-row counts across splits the last few global steps of an epoch can differ across topologies (bounded by the skew), which is documented on the parameter. With equal counts per split, full determinism is preserved β€” covered by a test. ## Testing 15 new tests in `test_elastic_dataloader.py` covering: default raise, invalid values, uniform and uneven skips (including epoch-end truncation), warn logging, selective callable handlers, wrong-row-count guardrail, determinism across runs and across world sizes (1/2/3/4) with skips, exact mid-epoch resume with skips on the same topology, elastic resume via `merge_state_dicts` (ws=2 β†’ ws=1), merge validation, and backward-compat loading of old checkpoints. Note: relying on CI for the test run β€” my local machine OOMs during the final link of the native extension. The change itself is pure Python. --------- Co-authored-by: Claude Fable 5 --- python/python/lancedb/streaming.py | 342 +++++++++++++-- .../python/tests/test_elastic_dataloader.py | 402 ++++++++++++++++++ 2 files changed, 717 insertions(+), 27 deletions(-) diff --git a/python/python/lancedb/streaming.py b/python/python/lancedb/streaming.py index 525ed3d63..b27e606a4 100644 --- a/python/python/lancedb/streaming.py +++ b/python/python/lancedb/streaming.py @@ -11,6 +11,11 @@ Provides StreamingDataset, a PyTorch IterableDataset that guarantees: - **Resumability**: state_dict / load_state_dict capture per-split consumption counts so training can resume from an exact mid-epoch position even when the distributed topology changes between runs. + +Transform failures on bad rows (e.g. nulls or NaNs from incomplete data) can +be tolerated with ``on_transform_error="skip"``; see the parameter +documentation on StreamingDataset for how this interacts with the guarantees +above.

manifest-authoritative (#3919) ## What is the bug? #3731 tries to distinguish a missing table from a corrupt table after Lance returns `DatasetNotFound`. It does that by listing the database parent and treating a physical `.lance` entry as evidence that the table exists. That premise is not sound for a listing database. Table creation writes data before atomically committing the first manifest, so the same physical prefix can represent a live concurrent create, abandoned uncommitted data, or an old empty directory. It is not evidence of a committed table. The parent listing also makes every missing-table open, including the create-on-miss path, perform work proportional to the number of sibling tables. Cloud `list_with_delimiter` exhausts all pages before returning. ## How does this PR fix the problem? This PR makes the committed Lance manifest the sole table-existence authority for listing-database opens: - `DatasetNotFound` maps directly to `TableNotFound`; no parent or target storage probe runs. - Other Lance load errors continue to propagate unchanged. - A physical directory, object prefix, or uncommitted data file alone does not block `Create`. - Concurrent `Create` requests are arbitrated by the conditional version-1 manifest commit: one succeeds and the loser receives `TableAlreadyExists`. - `table_names` is documented as physical discovery, not an atomic table-existence check. Its snapshot can contain an entry that is still being created, has only uncommitted storage, or is concurrently dropped. This removes the need for a new Lance object-store capability. LanceDB remains on the official Lance `v11.0.0-beta.6` dependency from `main`; the merge commit for lance-format/lance#7722 is an ancestor of that tag, so the ambiguous-GCS-500 corruption-prevention fix is retained. ## Performance evidence Lower is better. The benchmark uses real `.lance` directories with marker objects on the local filesystem; fixture creation and teardown are outside the timed region. Baseline is `origin/main` at `6fb976cf`, candidate is `e1240751`. Both were built from the same lockfile on the same macOS arm64 machine with the repository's `release` profile (fat LTO), then executed in alternating baseline/candidate order for three pairs. Each run used 10 warmups and 100 distinct missing-table opens per scale. The table reports the median of the three run-level percentiles. | Scenario / metric | Baseline | This PR | Benefit | | --- | ---: | ---: | ---: | | 1,000 real sibling directories, p50 | 11.905 ms | 21.042 us | 566x speedup | | 10,000 real sibling directories, p50 | 143.630 ms | 18.375 us | 7,817x speedup | | 100,000 real sibling directories, p50 | 1.991 s | 19.917 us | 99,984x speedup | | 100,000 real sibling directories, p95 | 2.346 s | 25.792 us | 90,965x speedup | These results validate removal of the sibling-cardinality dependency in this local-filesystem workload; they are not an extrapolation to production GCS latency. A structural object-store regression test separately asserts that opening one missing table performs zero parent-scoped `list`, `list_with_offset`, or `list_with_delimiter` calls. Run with: ```bash BENCH_SIBLINGS=1000,10000,100000 BENCH_WARMUPS=10 BENCH_TRIALS=100 \ cargo run --locked --release --quiet -p lancedb --example bench_open_missing_table ``` ## Correctness and compatibility boundaries - An empty `.lance` directory or orphan data without a committed manifest now opens as `TableNotFound` and may be replaced by a successful `Create`. - Two synchronized creators sharing one object store deterministically produce one success and one conditional-manifest conflict mapped to `TableAlreadyExists`. - A readable manifest remains authoritative; non-`DatasetNotFound` corruption, external-manifest, authorization, and object-store errors are not folded into `TableNotFound`. - `TableCorrupted` remains in the public error enum for compatibility, but this listing-database fallback no longer synthesizes it from an ambiguous physical footprint. - Reliably distinguishing `Missing`, `Creating`, and `Corrupt` would require explicit authoritative lifecycle/catalog metadata (for example a leased creation record).

every index a query relies on (#3780) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `exclusion_watermarks` resolved a single index and capped SSTable exclusion at that index's catch-up watermark. It now takes every index the query relies on and retains to the **lowest** of them, and the resolver collects arms together rather than returning at the first match. This is groundwork, not a fix for a reachable bug: `reject_unsupported` refuses hybrid search, so the vector and full-text arms are mutually exclusive and the list never holds more than one entry today. The generalisation is what the remaining work below plugs into. Unchanged: a plain scan uses the compaction watermark alone, an index with no catch-up entry contributes no cap, and a caught-up index falls back to the compaction watermark. Taking a minimum over more indexes can only lower a watermark, so the failure direction is "read an SSTable unnecessarily", never "miss rows". ## Tests Three in `lsm`: the existing lagging-index test updated for the new signature; `exclusion_watermark_takes_the_minimum_across_every_index_used` (two indexes at 7 and 4 against compaction at 9 β€” each alone stops at its own watermark, together the lower governs, order-independent); and `an_untracked_index_does_not_widen_a_lagging_sibling`. `cargo test -p lancedb --lib` β€” 45 lsm tests, 484 in the crate. `cargo fmt --check` clean. ## Follow-ups This crate pins lance to a released tag, so anything needing unreleased Lance symbols waits for a bump. 1. **Select legacy versus strict semantics from the feature bit.** On a table with `FLAG_MEM_WAL_INDEX_CATCHUP` set, a *missing* entry must mean "not caught up" and retain the SSTables, instead of leaving the compaction watermark unchanged. Needs the bit from lance-format/lance#8263. **This must land before any table is activated** β€” otherwise the bit is set while queries still read permissively. 2. **Collect scalar and bitmap-family prefilter indexes.** The genuinely multi-index query is a vector search with a scalar prefilter, and it is gated on the vector index alone today. Identifying the others needs the planner's chosen indexes, not the columns the filter names, so it needs a Lance-side helper. 3. **Verify a retained SSTable can actually answer.** Both base and SSTable arms use `fast_search`; a source without a compatible index contributes nothing, so retention alone does not guarantee its rows are returned. Needs a flat-search fallback or an explicit error in Lance's `LsmScanner`. 4. **Planner-level integration tests.** Current tests exercise the watermark arithmetic directly. End-to-end coverage over real queries β€” prefilter forms, legacy versus activated, missing index and missing shard entries β€” depends on 1–3. --- rust/lancedb/src/table/query/lsm.rs | 198 ++++++++++++++++++++-------- 1 file changed, 146 insertions(+), 52 deletions(-) diff --git a/rust/lancedb/src/table/query/lsm.rs b/rust/lancedb/src/table/query/lsm.rs index 074d13476..7ccdedf5a 100644 --- a/rust/lancedb/src/table/query/lsm.rs +++ b/rust/lancedb/src/table/query/lsm.rs @@ -84,9 +84,8 @@ pub(super) async fn create_lsm_plan( let pk_columns = pk_columns(&ds_ref)?; // The base index an indexed arm relies on may lag compaction; resolve it so the // snapshot retains SSTables the index has not yet caught up to. - let arm_index = arm_maintained_index_name(&ds_ref, &query, &details).await?; - let (snapshots, in_memory) = - build_read_context(table, &ds_ref, &details, arm_index.as_deref()).await?; + let arm_indexes = arm_maintained_index_names(&ds_ref, &query, &details).await?; + let (snapshots, in_memory) = build_read_context(table, &ds_ref, &details, &arm_indexes).await?; let limit = query.base.limit; let offset = query.base.offset; @@ -232,28 +231,36 @@ fn pk_columns(dataset: &Dataset) -> Result> { Ok(pk) } -/// Per-shard SSTable exclusion watermark: the generation at or below which SSTables -/// are safe to drop for this arm.

recorded index catch-up, as an explicit activation (#3911) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit > Stacked on #3780. Blocked only on #3922 (`lance` β†’ `v11.0.0-beta.6`), so CI > stays red until that lands. ## Missing coverage must mean "not known to be covered" #3780 caps the SSTable exclusion watermark at an index's recorded catch-up when there is one, and silently ignores the case where there is none. On a table that requires catch-up, an absent entry means the index is *not* known to hold the compacted rows β€” and the LSM base arm reads base through the index (`fast_search`, no brute-force tail), so dropping that SSTable loses those rows for that query. ```rust Some(caught_up) => watermark = watermark.min(caught_up), None if catchup_required => watermark = 0, // retain everything None => {} ``` `catchup_required` reads the manifest feature bit directly, and requires both words: a half-set manifest is treated as legacy, which is the conservative side. Without the bit the field is not maintained at all, so absence carries no information and behaviour is unchanged. ## Activation, as a table-level entry point `Table::require_mem_wal_index_catchup()` performs the one-way switch, separate from `set_lsm_write_spec`: a table carrying the bit retains every generation until something records catch-up, so it has to follow the deployment of whatever repairs coverage, not the creation of the table. This is a convenience, not the only path β€” a writer holding the dataset calls the equivalent on `DatasetMemWalExt`, which is what the WAL pod does. Lance enforces the preconditions either way: the MemWAL index must exist, and the table must not already carry `compacted_sstables` from before this protocol, since those numbers cannot be validated. ## Still correct after the Lance rework lance-format/lance#8481 replaced the transmitted `IndexCatchupAdvance` with a position derived at commit time from the version a transaction read. That changed how a writer earns coverage; it did not change what a reader may conclude from its absence. The rule here, and the field it reads, are unchanged. ## Tests Existing `exclusion_watermarks` unit tests carry the new argument. Coverage against a real dataset follows once #3922 lands and this can build. --- rust/lancedb/src/table.rs | 27 ++++++++++ rust/lancedb/src/table/merge/lsm.rs | 30 +++++++++++ rust/lancedb/src/table/query/lsm.rs | 78 +++++++++++++++++++++++++---- 3 files changed, 124 insertions(+), 11 deletions(-) diff --git a/rust/lancedb/src/table.rs b/rust/lancedb/src/table.rs index 32b6bcebc..10822cafa 100644 --- a/rust/lancedb/src/table.rs +++ b/rust/lancedb/src/table.rs @@ -637,6 +637,15 @@ pub trait BaseTable: std::fmt::Display + std::fmt::Debug + Send + Sync { message: "set_lsm_write_spec is not supported on this table type".into(), }) } + /// Switch this table to required index catch-up, one way. + /// + /// The default implementation returns `NotSupported`.

computed columns by SQL expression (#3937) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit add_columns().computed("doubled", "x * 2") stores the expression in field metadata and commits the column empty; a later refresh fills it. Type and inputs are derived from the expression. The declaration stays authoritative for its lifetime: writes that would give the column a value (append, update, merge, SQL insert), schema changes that would break the stored expression or reshape its output, metadata edits, volatile expressions, declaration metadata arriving through any path but the validated declare call, and LSM write specs in either order against latest committed state are all refused. The LSM check also refuses on the mem-wal catch-up feature flag, which outlives unset and marks retained SSTable rows. Simultaneous declare/install interleavings conflict at commit via lance's mem-wal rule (lance#8539).

A row that holds a value keeps it; deleted and already-filled rows never reach the expression, so a poison value in them cannot fail the refresh.
