AgentTune: An Agent-Based Large Language Model Framework for Database Knob Tuning

Summary: AgentTune: an agent-based LLM framework decomposing DB knob tuning into four specialized collaborating agents. Reconstructs valid knob ranges, prunes the search space and recommends safe configs to reduce replays and avoid invalid/crashing settings. (summarized by gpt-5-mini on Feb 11 2026)
