java.lang.Object

org.apache.calcite.adapter.enumerable.CodeGenerationBenchmark

Direct Known Subclasses:

CodeGenerationBenchmark_jmhType_B1

public class CodeGenerationBenchmark
extends Object

A benchmark of the main methods that are dynamically generating and compiling Java code at runtime.

The benchmark examines the behavior of existing methods and evaluates the potential of adding a caching layer on top.
