Zhu Zhu commented on FLINK-13639:
---------------------------------
+1 for this proposal.
A structured ID system would be helpful for debugging and further
development(e.g. fast lookup).
Maybe later we should even refactor the ExecutionAttemptID as well, to make it
(ExecutionVertexID, attemptNumber) ? (ExecutionVertexID consists of JobVertexID
and subtaskIndex).
> Consider refactoring of IntermediateResultPartitionID to consist of
> IntermediateDataSetID and partitionIndex
