LEON: A New Framework for ML-Aided Query Optimization
Summary: LEON augments mature expert optimizers with deployment-specific ML rather than replacing them with RL. Pairwise ranking, uncertainty-guided exploration, and model-guided pruning improve plan quality, training efficiency, stability, and planning cost. (summarized by gpt-5.6-luna on Jul 24 2026)
