UDO: Universal Database Optimization using Reinforcement Learning

Understand

UDO is a versatile tool for offline tuning of database systems for specific workloads.

• UDO can consider a variety of tuning choices, reaching from picking transaction code variants over index selections up to database system parameter tuning.
• UDO uses reinforcement learning to converge to near-optimal configurations, creating and evaluating different configurations via actual query executions (instead of relying on simplifying cost models).
• To cater to different parameter types, UDO distinguishes heavy parameters (which are expensive to change, e.g.
