Efficient Query Re-optimization with Judicious Subquery Selections

Summary: QuerySplit re-optimization generates subqueries from the logical plan, not the global plan. A cost function favors small, low-damage subqueries to delay large joins; in PostgreSQL, it yields 35% faster JOB vs baselines, within 4% of optimal. (summarized by gpt-5-nano on Feb 09 2026)
