> After a scale up/down, autoscaler measures the true processing rate via busy
> time metrics to be negative as it uses num-records-in metric before the scale
> up/down -
> [https://github.com/apache/flink-kubernetes-operator/blob/main/flink-autoscaler/src/main/java/org/apache/flink/autoscaler/ScalingMetricEvaluator.java#L459]
>
> We need to find the first metric after the last scaling action instead to
> compute the true processing rate
