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

             Summary: Avoid copying when converting byte[] to ByteString in StateFun
                 Key: FLINK-21498
                 URL: https://issues.apache.org/jira/browse/FLINK-21498
             Project: Flink
          Issue Type: Bug
          Components: Stateful Functions
            Reporter: Tzu-Li (Gordon) Tai
            Assignee: Tzu-Li (Gordon) Tai


There's a few places in StateFun where we can be more efficient with byte[] to Protobuf ByteString conversions, by just wrapping the byte[] instead of copying, since we know that the byte array can no longer be mutated.
