[jira] [Created] (BEAM-13080) Specify numBuckets in Python Reshuffle

Inigo San Jose Visiers created BEAM-13080:
---------------------------------------------

             Summary: Specify numBuckets in Python Reshuffle
                 Key: BEAM-13080
                 URL: https://issues.apache.org/jira/browse/BEAM-13080
             Project: Beam
          Issue Type: New Feature
          Components: sdk-py-core
            Reporter: Inigo San Jose Visiers


While Java has `withNumBuckets` to set the amount of generated keys, Python doesn't.

This is particularly need when your input data is not so high and you need to take advantage for DoFn methods `start / finish bundle`.
