feat: bump lance 2→4 + datafusion 51→52 + deltalake 0.30→0.31#273
Merged
Conversation
Dep upgrade across all workspace crates. Arrow stays at 57. Version matrix: lance 2.0.1 → 4.0.1 (lancedb 0.27 compatible) lance-linalg 2.0.1 → 4.0.1 lance-arrow 2.0.1 → 4.0.1 lance-index 2.0.1 → 4.0.1 lance-namespace 2.0.1 → 4.0.1 datafusion 51 → 52 datafusion-* 51 → 52 (common, expr, sql, functions-aggregate) deltalake 0.30 → 0.31 (0.32 needs arrow 58, incompatible) arrow 57 → 57 (unchanged) object_store 0.12 → 0.12 (unchanged) API breaks fixed: 1. lance-namespace: NamespaceError::invalid_input() now takes 1 arg (message only), not 2 (message + location). Removed `location!()` calls and unused `snafu::location` import in directory.rs. 2. deltalake: DeltaTable no longer implements TableProvider directly. Fixed table_readers.rs to go through DeltaTableProvider::try_new( snapshot, log_store, scan_config) — gets EagerSnapshot via delta_table.snapshot()?.snapshot().clone(). Workspace compiles clean (4 pre-existing warnings, 0 errors). https://claude.ai/code/session_01SbYsmmbPf9YQuYbHZN52Zh

Datafusion 52's switch from xz2 to liblzma eliminated the dual links="lzma" collision that blocked auth-rls + lance simultaneously. smb-bridge::rls module now ships RlsRewriter wiring; the previously-impossible feature combo `auth-rls + lance` builds clean. 140 tests pass with auth-rls mongo lance wal all enabled. PR follows on smb-office-rs.
