April 2026: Delivered native Lance format support in Doris via Rust FFI (PR with commit b613c3711c9ebbea5b31a48d5bed0b35b353517d), enabling SQL queries over Lance datasets from local disk and S3. Implemented a Rust-based Lance reader with Arrow C Data Interface for zero-copy data exchange between Rust and C++, and wired end-to-end access through s3() and local() TVFs with practical usage examples. Validated core capabilities on a live cluster (SELECT, WHERE, LIMIT, COUNT, aggregations) and prepared time-travel/config readiness. Established robust build/test coverage and deployment notes, including opt-in BUILD_RUST_READERS and ~430MB Rust static library. Documented architecture and outlined next steps for broader Lance adoption (catalog creation, fragment-level scans, FE pushdown, and caching).
