COMPARE: Accelerating Groupwise Comparison in Relational Databases for Data Analytics

Summary: Proposes Compare, a relational operator for concise enumeration and cross-subset comparison. Optimizations exploiting Compare semantics, implemented in SQL Server, yield speedups over standard plans, UDFs, and middleware for large-scale analytics. (summarized by gpt-5-nano on Feb 09 2026)
