POP/FED: Progressive Query Optimization for Federated Queries in DB2
Summary: POP/FED extends progressive optimization for federated queries addressing stale statistics that mislead plan choice. Enables risk-controlled iterative reoptimizations with redundancy elimination and eager statistics; demonstrated on DB2 with POPMonitor. (summarized by gpt-5-nano on Feb 09 2026)
