Overlay Bitmap Encoding for Efficient Consumption of Apache Parquet Files
Summary: Recasts Parquet column chunks as compressed overlay-bitmaps, making indexes the physical representation rather than an adjunct. Integrated in Parquet C++/SAP IQ, it enables row-level predicate pushdown, improving compression and reducing loads by up to 100×. (summarized by gpt-5.6-luna on Aug 28 2026)
