Stephan Ewen commented on FLINK-17295:
--------------------------------------
Is the size of the ExecutionAttemptID really an issue here? How many times is
that one replicated in the deployment descriptors that this makes a real
difference?
We could add a full-blown UUID to the ExecutionAttemptID, which is not printed
in logs or anything, just used on equality comparisons. That should get us on
the same safe side as we were before.
> Refactor the ExecutionAttemptID to consist of ExecutionVertexID and
> attemptNumber
