Debunking the Myth of Join Ordering: Toward Robust SQL Analytics

Summary: Robust Predicate Transfer (RPT) for acyclic joins; introduces LargestRoot and SafeSubjoin to achieve provable robustness to arbitrary join orders. Implemented in DuckDB; evaluated on TPC-H/JOB/TPC-DS/DSB, delivering up to 1.6x robustness improvement and ~1.5x end-to-end speedup. (summarized by gpt-5-nano on Feb 09 2026)
