Eddies: Continuously Adaptive Query Processing

Summary: Introduce eddies: continuously adaptive query processing that reorders operators on the fly in shared-nothing DBs. Guided by symmetry moments and barrier coordination, a learner merges optimization with execution, delivering gains in dynamic workloads. (summarized by gpt-5-nano on Feb 09 2026)
