---------------------------------

             Summary: Specialized CopyableValue serializers and comparators
                 Key: FLINK-3868
                 URL: https://issues.apache.org/jira/browse/FLINK-3868
             Project: Flink
          Issue Type: Improvement
          Components: Core
    Affects Versions: 1.1.0
            Reporter: Greg Hogan
            Assignee: Greg Hogan


This need was discussed on the mailing list [1] and will be obviated by code generation for POJO serializers and comparators [2] (as I understand, i.e., {{LongValue}} will now simply be treated as a POJO which happens to contain a {{long}} and a specialized serializer and comparator will be generated).

In the meantime, and since {{ValueTypeInfo}} will need to be reworked to use the new generators, I think it is worthwhile to add specialized serializers and comparators for the {{CopyableValue}} types.

This will also provide another point of comparison for the performance of the generated serializers and comparators.
