RABIT: Efficient Range Queries with Bitmap Indexing
Summary: RABIT generalizes bitmap indexes with Group Encoding and density-aware bitvector merging (choose compressed/decompressed, SIMD) to support fast range queries and low-latency updates for any-cardinality attributes. A multi-layer update design provides lightweight MV snapshots and index-only scans with single-version bitvectors, delivering up to 2.2× faster RQs, 530× faster updates, 118× smaller index vs trees and 14.8× TPC‑H speedups.
