ConEx: A System for Monitoring Queries

Summary: ConEx offers real-time, unified visualization of query execution with continuous progress updates and operator-status awareness for the plan. It introduces dynamic, efficient estimation techniques for key progress parameters to enable end-to-end monitoring inside a relational DBMS. (summarized by gpt-5-nano on Feb 09 2026)
