Instance-Optimal Acyclic Join Processing Without Regret: Engineering the Yannakakis Algorithm in Column Stores
Summary: SYA converts binary join plans into 2-phase Nested Semijoin Algebra (Lookup/Expand) plans and evaluates them by shredding in column stores to attain instance-optimal acyclic join evaluation. Provably avoids blowups and is no-regret vs binary plans; on 1,849 queries it speeds 85.3% up to 62.5x. (summarized by gpt-5-mini on Feb 09 2026)
