npawar opened a new pull request #5257: Use GroovyCodeSource to cache compiled source URL: https://github.com/apache/incubator-pinot/pull/5257 Using GroovyShell results in parsing of the script for every record. Instead, using GroovyCodeSource along with GroovyClassLoader, so that compiled source is cached. Results from benchmark, comparing a concat function and a find max in array function, executed using a) java b) groovy shell c) groovy code source ``` Benchmark Mode Cnt Score Error Units BenchmarkTransformFunctions.groovyCodeSourceConcat avgt 3 0.803 ± 0.182 us/op BenchmarkTransformFunctions.groovyShellConcat avgt 3 3070.285 ± 6152.874 us/op BenchmarkTransformFunctions.javaConcat avgt 3 0.717 ± 0.093 us/op ``` ``` Benchmark Mode Cnt Score Error Units BenchmarkTransformFunctions.groovyCodeSourceMax avgt 3 7.564 ± 0.923 us/op BenchmarkTransformFunctions.groovyShellMax avgt 3 4244.830 ± 12903.002 us/op BenchmarkTransformFunctions.javaMax avgt 3 4.413 ± 0.473 us/op ```
