------------------------------------
Sure [~wangm92] , I will assign this to you. I think the best way to start
would be a FLIP to describe the design and what problem we are solving and how
exactly so that other community members can also understand and participate in
the review :)
> Consider using the autoscaler to detect slow taskmanagers

> Key: FLINK-30680
> 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.
