----------------------------------
Assignee: (was: Gyula Fora)
> Do not redeploy taskmanagers on standalone application scaling
> ---------------------------------------------------------------
>
> Key: FLINK-30404
> URL: https://issues.apache.org/jira/browse/FLINK-30404
> Project: Flink
> Issue Type: Improvement
> Components: Kubernetes Operator
> Reporter: Gyula Fora
> Priority: Major
>
> The standalone deployment mode allows in-place scale ups when reactive mode
> is configured but in other cases it deletes and redeploys both task and
> jobmanagers.
> Without reactive mode, we could improve the current behaviour by not
> redeploying taskmanagers during scale changes. In theory only the jobmanager
> needs to be redeployed in these cases (as it cannot run multiple jobs in
> application mode).
> This improvement would greately improve the startup times in busy clusters
> and make scaling more robust
