Gyula Fora reassigned FLINK-32589:
----------------------------------
Assignee: Gyula Fora
> Carry over parallelism overrides to prevent users from clearing them on
> updates
> -------------------------------------------------------------------------------
>
> Key: FLINK-32589
> URL: https://issues.apache.org/jira/browse/FLINK-32589
> Project: Flink
> Issue Type: Improvement
> Components: Autoscaler, Kubernetes Operator
> Reporter: Maximilian Michels
> Assignee: Gyula Fora
> 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).
