VerdictDB: Universalizing Approximate Query Processing

Summary: VerdictDB: universal, database-agnostic AQP via driver-level middleware that rewrites queries without backend changes. Provides approximate answers with error estimates across engines (Impala, Spark SQL, Redshift), delivering 171x speedups and <3% error. (summarized by gpt-5-nano on Feb 09 2026)
