[GitHub] [beam] mosche opened a new issue, #27533: [Performance]: GetterBasedSchemaProvider.fromRowFunction doesn't lend itself well for JIT optimizations

mosche opened a new issue, #27533:
URL: https://github.com/apache/beam/issues/27533

   ### What would you like to happen?
   
   The conversion of rows to the external object is rather inefficient. The code to convert `Row` fields to the external field types required for the constructor / setters in `FromRowUsingCreator` is branch heavy and rather hard to optimize for Java's JIT compiler.
   
   Benchmarks for GetterBasedSchemaProvider are available here: https://s.apache.org/beam-community-metrics/d/kllfR2vVk/java-jmh-benchmarks?orgId=1
