Db2une: Tuning Under Pressure via Deep Learning

Summary: Db2une automatically tunes Db2 knobs by encoding queries with QBERT (transformer-based embeddings) and driving a stability-oriented on-policy deep reinforcement learning agent to balance performance and resource use. Multi-phase, metadata-driven training leverages cost estimates and interpolation to avoid executing queries, enabling scalable tuning of large workloads and outperforming expert and state-of-the-art recommenders.
