[jira] [Created] (BEAM-2365) Use highest protocol for pickle coder.

Robert Bradshaw created BEAM-2365:
-------------------------------------

             Summary: Use highest protocol for pickle coder.
                 Key: BEAM-2365
                 URL: https://issues.apache.org/jira/browse/BEAM-2365
             Project: Beam
          Issue Type: Bug
          Components: sdk-py
            Reporter: Robert Bradshaw
            Assignee: Robert Bradshaw


E.g. for large NumPy arrays, this is a 3x reduction in size and a 61x reduction in cpu. 

Note that dill already does this (but the FastPrimitivesCoder intentionally uses cPickle instead).
