AutoSteer: Learned Query Optimization for Any SQL Database
Summary: AutoSteer: a portable, learning-based system that steers any SQL optimizer exposing tunable knobs by extending Bao with automated hint-set discovery and low-integration APIs for monolithic and disaggregated engines. Evaluated on PostgreSQL, Presto, Spark, MySQL and DuckDB, it outperforms native optimizers (up to ~40% for Presto), matches Bao while reducing human supervision, and ships open-source with a visual tool.
