DOT: Dynamic Knob Selection and Online Sampling Automates Database Tuning Without DBA Expertise

arXiv 2603.15540·medium signal

DOT (arXiv 2603.15540) automates DBMS configuration tuning by dynamically identifying the most impactful knobs per workload, then applying online sampling to converge faster than static tuning methods. DBMS configuration is currently a manual, expertise-heavy process — DOT removes that dependency and adapts to shifting workload patterns at runtime. Directly relevant for builders running PostgreSQL or similar databases under variable agentic query patterns.
