Ankur Goenka updated BEAM-7199:
-------------------------------
    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.

  was:Make pre_optimize=all as the default pipeline graph optimization method 
for python pipelines.


> Better optimize Portable pipelines
