Query Execution Techniques for Caching Expensive Methods

Summary: Evaluates caching of unary methods in OR/O-O queries with duplicates; compares memoization, sorting, and Hybrid Cache. Hybrid Cache dominates memoization and often beats sorting; adds unary-hash optimizations. (summarized by gpt-5-nano on Feb 09 2026)
