> Use max busytime instead of average to compute true processing rate

> Key: FLINK-30652
> URL: https://issues.apache.org/jira/browse/FLINK-30652
> Project: Flink
> Issue Type: Improvement
> Components: Autoscaler, Kubernetes Operator
> Affects Versions: kubernetes-operator-1.4.0
> Reporter: Gyula Fora
> Assignee: Gyula Fora
> Priority: Critical
> Labels: pull-request-available
> Fix For: kubernetes-operator-1.4.0
>
>
> Currently we use the some of busyTimes and processed records to estimate the
> true processing rate.
> This computation however is not correct when any data skew is present as TPR
> is not fully additive. The first task to reach 100% utilization will set a
> limit to the pipeline processing rate through backpressure.
> To avoid this we should use the max busyTime and compute the TPR from that.
