JingsongLi opened a new pull request, #731: URL: https://github.com/apache/paimon-rust/pull/731
## What changed - add the `multivalue` global-index type for array columns - build Java-compatible bitmap postings for every non-null array element - support `ARRAY_CONTAINS`, `ARRAYS_OVERLAP`, and `ARRAY_CONTAINS_ALL` in predicates, global-index scans, Arrow residual evaluation, and DataFusion pushdown - add Java-compatible `MVIM` element-type metadata, including the Java `STRING` signature - expose create/drop procedure support and document SQL usage ## Behavior Null arrays, empty arrays, and null elements do not create postings. Duplicate elements in one row are deduplicated by the bitmap. Empty `ARRAY_CONTAINS_ALL` falls back to residual evaluation because the index cannot distinguish null arrays from empty arrays. ## Validation - `cargo test -p paimon --all-targets --features fulltext,vortex --no-fail-fast` - `cargo clippy --locked --all-targets --workspace --features fulltext,vortex -- -D warnings` - focused DataFusion array-function pushdown tests - end-to-end multivalue build/read/query coverage, including nulls, empty arrays, duplicate elements, metadata compatibility, and all three query operators -- This is an automated message from the Apache Git Service.
