Description
Python has an experimental flag pre_optimize=all which does pre-optimization of python pipelines by fusing operators.
Python optimization is expected to be better than the one in java because it has more information about the pipeline.
Make java pipeline optimization at par with python so that the benefits can be shared by all languages.
