JingsongLi opened a new pull request, #732:
URL: https://github.com/apache/paimon-rust/pull/732

   ## What changed
   
   - add `ARRAY_CONTAINS`, `ARRAYS_OVERLAP`, and `ARRAY_CONTAINS_ALL` to the 
predicate model and REST deserialization
   - evaluate array predicates exactly over Arrow list arrays, including 
null/empty arrays, duplicate literals, decimals, NaNs, and signed zero
   - push DataFusion `array_has`, `array_has_any` / `arrays_overlap`, and 
`array_has_all`, retaining DataFusion residuals where semantics differ
   - prune all-null array files through predicate stats
   - extract `TIME` values from Arrow and decode Java-compatible LZ4/LZO bitmap 
blocks
   
   ## Why
   
   These are reusable predicate and read-compatibility capabilities independent 
of the MultiValue global index implementation in #731. Moving them into a 
prerequisite PR keeps #731 focused on the writer, metadata, scanner, and 
procedure wiring.
   
   The exact array residual follows Java Paimon semantics: all NaN payloads 
compare equal, signed zero remains distinct, decimal values compare across 
scales, NULL arrays do not match, and an empty `ARRAY_CONTAINS_ALL` literal 
matches only non-null arrays.
   
   ## Validation
   
   - `cargo test -p paimon --all-targets --features fulltext,vortex 
--no-fail-fast`
   - `cargo test -p paimon-datafusion --lib filter_pushdown::tests 
--no-fail-fast`
   - `cargo clippy --workspace --all-targets --features fulltext,vortex -- -D 
warnings`
   
   All checks pass locally.
