Gyula Fora commented on FLINK-32589:
------------------------------------
So just to be clear, do you suggest adding a new status field with the
autoscaler overrides and always applying them to the spec?
This way we could actually get rid of any spec modification done by the
autoscaler module and let the reconciler simply apply it without updating it in
k8s.

> Key: FLINK-32589
> URL: https://issues.apache.org/jira/browse/FLINK-32589
> Project: Flink
> Issue Type: Improvement
> Components: Autoscaler, Kubernetes Operator
> Reporter: Maximilian Michels
> Priority: Major
>
> The autoscaler currently sets the parallelism overrides via the Flink config
> {{pipeline.jobvertex-parallelism-overrides}}. Whenever the user posts specs
> updates, special care needs to be taken in order to carry over existing
> overrides. Otherwise the job will reset to the default parallelism
> configuration. Users shouldn't have to deal with this. Instead, whenever a
> new spec is posted which does not contain the overrides, the operator should
> automatically apply the last-used overrides (if autoscaling is enabled).
