Spark SQL Expression Optimizations: LIKE ALL/ANY, TRIM Function Improvements, and Constant Folding
This article examines Spark SQL expression-level optimizations, focusing on redesigning LIKE ALL and LIKE ANY to reduce memory and stack usage, refactoring the TRIM function for better code reuse and performance, and implementing constant folding to cache computed constant expressions, thereby enhancing query efficiency in big-data workloads.
