             Summary: Add a Reshuffle PTransform preventing fusion of the surrounding transforms
                 Key: BEAM-8292
                 URL: https://issues.apache.org/jira/browse/BEAM-8292
             Project: Beam
          Issue Type: New Feature
          Components: sdk-go
            Reporter: John Patoch


Reshuffle is a PTransform that takes a PCollection<A> and shuffles the data to help increase parallelism.
Reshuffle adds a temporary random key to each element, performs a
 GroupByKey, and finally removes the temporary key.
