QTune: A Query-Aware Database Tuning System with Deep Reinforcement Learning

Summary: QTune: a query-aware database tuning system using a Double-State DDPG (DS-DDPG) deep RL model to pick configurations from rich SQL-query features. Supports query-, workload-, and cluster-level tuning; validated across three real DB systems, it outperforms state-of-the-art tuners. (summarized by gpt-5-nano on Feb 09 2026)
