Beschreibungen/Notizen

• Nowadays, data systems, including IBM Db2 have dozens of knobs (configuration parameters). These knobs significantly affect the runtime of queries. We present the design of and a demonstration plan for a query-informed, efficient tuning system, BLUTune, which utilizes deep reinforcement learning to tune configurations. Using synthetic and real workloads, we demonstrate how BLUTune can help users to understand the semantics of analytical queries, including their execution plans, and interactively tune data systems to improve performance.
