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

             Summary: Remove useless ResultPartitionID from AddCredit message
                 Key: FLINK-16257
                 URL: https://issues.apache.org/jira/browse/FLINK-16257
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Network
            Reporter: Zhijiang
            Assignee: Zhijiang
             Fix For: 1.11.0


The ResultPartitionID in AddCredit message is never used on upstream side, so we can remove it to cleanup the codes. There would have another two benefits to do so:
 # Reduce the total message size from previous 52 bytes to 20 bytes.
 # Decouple the dependency with `InputChannel#getPartitionId`
