PET: Reducing Database Energy Cost via Query Optimization
Summary: PET augments PostgreSQL’s optimizer with compile-time power modeling and a composite time–energy cost model. DBAs can tune the performance/energy tradeoff at runtime, exposing energy-efficient plans conventional optimizers overlook. (summarized by gpt-5.6-luna on Jul 24 2026)
