0.2.0

  • Add opt-in, application-supervised LanceDB.TableCache: shared table opens, retained sessions, bounded background multi-index warming, LRU/idle eviction, explicit invalidation, status and telemetry. Track table version and index UUID so changed indexes can be warmed again; discard stale task results.
  • Move blocking table/index inspection, index prewarming and deletion, and table listing/deletion to dirty I/O schedulers so storage waits leave dirty CPU schedulers available.
  • Normalize native metrics recorder installation failures to LanceDB.Error, matching Telemetry.enable_native_metrics/0's documented return type.
  • Add typespecs for every public library function, checked by a regression test.
  • Reject stale selected native builds in CI before compilation, requiring matching immutable build and checksum manifests for committed native changes.
  • Extend anonymous package and production-release checks with supervised caching, background warming of two FTS indexes, and query reuse of warmed caches.
  • Remove the obsolete pre-release migration guide.

This release selects new verified native binaries for Linux x86_64 and ARM64. LanceDB SDK 0.37.1 and platform requirements are unchanged.

Breaking changes

0.1.1

  • Add LanceDB.Table.cache_stats/1 for the handle's actual session: index and metadata cache usage, entries, hits, and misses, without a global recorder. Capacity is unavailable in the pinned SDK and is reported as nil.
  • Add optional :timeout_ms to connect and table opening. Native work runs on Tokio, yields BEAM schedulers, and releases read admission on cooperative timeout or caller death. One deadline covers the entire native operation.
  • Accept :index_cache_size_bytes and :metadata_cache_size_bytes during initial connection setup, avoiding the extra SDK connection needed by per-open budgets. Separate connections have independent sessions; tables using one connection share its budgets. Existing per-open isolation remains.
  • Document actual session sharing, cancellation limits, and reproducible local/MinIO connect and open benchmarks.

Requires the new native build selected in this release. Normal installation downloads its verified Linux x86_64 or ARM64 binary without compiling Rust. LanceDB SDK 0.37.1 and platform requirements are unchanged.

0.1.0

Initial public release of LanceDB for Elixir, using LanceDB Rust SDK 0.37.1.

  • Local and S3-compatible storage, with explicit schemas and nested data types.
  • Vector, batch vector, multivector, full-text, and hybrid queries, plus filters, projections, streaming, and direct row retrieval.
  • Scalar, vector, and full-text indexes; streaming writes, updates, merges, and schema evolution.
  • Table history, tags, branches, clones, metadata, blobs, and maintenance.
  • Structured errors, execution deadlines, telemetry, and asynchronous native jobs.
  • Precompiled Linux x86_64 and ARM64 NIFs with immutable build IDs and verified checksums. Normal installation does not require Rust.

Requires Elixir 1.20 or later in the 1.x series. Linux x86_64 requires glibc 2.35 or later; Linux ARM64 requires glibc 2.39 or later.
