Aqua: A Fast Decision Support System Using Approximate Query Answers

Summary: Aqua provides fast approximate aggregation for OLAP by rewriting queries to run on precomputed synopses stored in the DBMS. Synopses are incrementally maintained and come with quality guarantees, enabling DBMS-agnostic deployment atop commercial RDBMS. (summarized by gpt-5-nano on Feb 09 2026)
