@gyfora if the effort is reasonable, it would be great to try this out on
your topology. As soon as you give your +1, I could merge this change :-)
> Flink treats every task as stateful (making topology changes impossible)

> Key: FLINK-5985
> URL: https://issues.apache.org/jira/browse/FLINK-5985
> Project: Flink
> Issue Type: Bug
> Components: State Backends, Checkpointing
> Affects Versions: 1.2.0
> Reporter: Gyula Fora
> Priority: Critical
>
> It seems that Flink treats every Task as stateful so changing the topology
> is not possible without setting uid on every single operator.
> If the topology has an iteration this is virtually impossible (or at least
> gets super hacky)
