----------------------------------------
> Autoscaler doesn't scale down on 0 load
> ---------------------------------------
>
> Key: FLINK-30575
> URL: https://issues.apache.org/jira/browse/FLINK-30575
> Project: Flink
> Issue Type: New Feature
> Components: Autoscaler, Kubernetes Operator
> Reporter: Gyula Fora
> Assignee: Maximilian Michels
> Priority: Major
> Labels: pull-request-available
> Fix For: kubernetes-operator-1.5.0
>
>
> The logic for computing true processing rates rely on recordsProcessed /
> recordProcessingTime style computations which do not really work well when
> everything is 0.
> This leads to no scaling actions when the load suddenly drops to 0. We should
> handle these special cases and scale the pipeline to some minimal parallelism.
