Gyula Fora updated FLINK-31936:
-------------------------------
Fix Version/s: kubernetes-operator-1.5.0
> Support setting scale up max factor
> -----------------------------------
>
> Key: FLINK-31936
> URL: https://issues.apache.org/jira/browse/FLINK-31936
> Project: Flink
> Issue Type: Improvement
> Components: Autoscaler
> Reporter: Zhanghao Chen
> Assignee: Zhanghao Chen
> Priority: Major
> Labels: pull-request-available
> Fix For: kubernetes-operator-1.5.0
>
>
> Currently, only scale down max factor is supported to be configured. We
> should also add a config for scale up max factor as well. In many cases, a
> job's performance won't improve after scaling up due to external bottlenecks.
> Although we can detect ineffective scaling up and would block further
> scaling, but it already hurts if we scale too much in a single step which may
> even burn out external services.
> As for the default value, I think 200% would be a good start.
