Yannakakis+: Practical Acyclic Query Evaluation with Theoretical Guarantees
Summary: Yannakakis+ provides a practical, constant-factor-efficient acyclic CQ evaluator with theoretical guarantees. It emits a conventional DAG plan for integration with SQL engines (DuckDB, PostgreSQL, SparkSQL, AnalyticDB), delivering 2x-5x speedups (avg 2.41x) on most queries.
