>                 URL: https://issues.apache.org/jira/browse/FLINK-30680
>             Project: Flink
>          Issue Type: New Feature
>          Components: Autoscaler, Kubernetes Operator
>            Reporter: Gyula Fora
>            Priority: Major
>
> We could leverage logic in the autoscaler to detect slow taskmanagers by comparing the per-record processing times between them.
> If we notice that all subtasks on a single TM are considerably slower than the rest (at similar input rates) we should try simply restarting the job instead of scaling it up.
