# lance-table

`lance-table` is an internal sub-crate for the
[Lance table format](https://lance.org/format/table/).

**Important Note**: This crate is **not intended for external usage**.
fix(deps): vendor lance-table 7.0.0 + lance#7480 so merge-updated tables survive filtered reads after deletes iss-merge-rowid-overlap-corrupts-filtered-reads / lance#7444: an update-style merge_insert over a merge-written fragment legally reuses the updated rows' stable row ids (row-id-lineage spec: updates preserve _rowid) while the superseded fragment keeps its full sequence plus a deletion vector. A later delete leaves the overlapping id range sparsely tiled, and lance-table 7.0.0's RowIdIndex::new asserted dense tiling — failing every filtered read that builds the id→address map ("Wrong range" debug assert; "all columns in a record batch must have the same length" or a silently-wrong batch in release). The upstream fix (lance#7480, merged 2026-07-01) landed hours AFTER v8.0.0 was cut, so no release ≤ 8.0.0 carries it. Consume it now as a vendored pin: vendor/lance-table is the pristine published 7.0.0 source plus ONLY the #7480 rowids/index.rs hunk (drop the false tiling assert; hard-error on the true invariant — one live id claimed by two fragments) and upstream's regression unit test, wired via [patch.crates-io]. The fix is read-side only, so already-written graphs become readable as-is — no data repair. Removal condition (see vendor/lance-table/README.omnigraph.md): drop the vendor dir + patch entry at the first Lance bump whose lance-table ships lance#7480 (9.0.0, or a backported 8.0.1). The surface guard filtered_scan_tolerates_merge_update_row_id_overlap keeps that honest in both directions. Turns the previous commit's red tests green. Full workspace gate passes (cargo test --workspace --locked --no-fail-fast, 68 suites). 2026-07-02 02:17:25 +03:00			`# lance-table`
