Yangze Guo commented on FLINK-17295:
------------------------------------
I compare the entire job runtime in the parallelism of 2000. After a cluster
warm up, There is no difference in running time (29.4s vs 30s). Maybe this
result will give us more confidence to introduce a random element.
> Refactor the ExecutionAttemptID to consist of ExecutionVertexID and
> attemptNumber
