Cody Schroeder created BEAM-4405:
------------------------------------

             Summary: Support SortValues GroupByKey extension
                 Key: BEAM-4405
                 URL: https://issues.apache.org/jira/browse/BEAM-4405
             Project: Beam
          Issue Type: Improvement
          Components: sdk-go
            Reporter: Cody Schroeder
            Assignee: Henning Rohde


A port of the Java [SortValues|https://beam.apache.org/documentation/sdks/java-extensions/] extension would be helpful in the Go SDK.

Brief summary of the extension: for a GroupByKey or CoGroupByKey operation, allow the user to specify that the value streams per key should be sorted (either by their byte encoding or by a secondary sort key) upon delivery the user's ParDo.
