Bridging the Indexing Gap in Fused GPU Query Engines
Summary: Fused bitmap indexing brings selective-query acceleration to GPU engines via a virtual program for arbitrary Boolean predicates. It fuses index access with lookups, joins, and aggregation in registers, while three-valued candidate checking handles misaligned bins without materialization.
