Raster is Faster: Rethinking Ray Tracing in Database Indexing
Summary: Challenges premise that GPU ray tracing is best for column indexing; proposes rasterization-based RasterScan using arithmetic value comparisons instead of ray-triangle intersections while preserving the RT data model. Evaluation on large datasets shows consistent, often order-of-magnitude, speedups in index build and search. (summarized by gpt-5-mini on Feb 09 2026)
