### Purpose Related issue: #34 The Rust file-index layer had predicate composition and row-level selection support, but no Bitmap reader, so it could not consume Bitmap indexes written by Java Paimon. Bitmap V2 also requires block-level lookup to avoid eagerly materializing high-cardinality dictionaries. ### Brief change log - Decode Java-compatible Bitmap V1 and V2 metadata and value encodings. - Support Boolean, integer, floating-point, date/time, timestamp, and string types. - Preserve Java floating-point ordering, NaN canonicalization, and conservative signed-zero predicate semantics. - Deserialize singleton and RoaringBitmap32 entries on demand. - Keep V2 secondary-index blocks lazy and parse only blocks selected by predicate literals. - Return row selections for Eq, In, NotEq, NotIn, IsNull, and IsNotNull. - Add Java V1/V2 golden fixtures, malformed-input tests, and a high-cardinality multi-block regression test. ### Tests - `cargo fmt --all -- --check` - `cargo clippy --locked --all-targets --workspace --features fulltext,vortex -- -D warnings` - `cargo test --locked -p paimon --all-targets --features fulltext,vortex` - `cargo test --locked -p paimon-rest-server --all-targets` - Java release-2.0 Bitmap writer/reader fixture probe ### API and Format No public API or writer-format changes. This adds read support for existing Java Bitmap V1/V2 payloads. ### Documentation No documentation changes. -- This is an automated message from the Apache Git Service.
