Optimizing Database Expression Evaluation with JIT Compilation Using Gandiva

This article explains how Just‑In‑Time (JIT) compilation, particularly via the Gandiva expression compiler built on LLVM and Apache Arrow, can dramatically accelerate database expression evaluation by transforming abstract syntax trees into native vectorized code, addressing traditional interpretation bottlenecks and improving CPU‑bound query performance.
