Piotr Nowojski updated FLINK-20724:
-----------------------------------
Description:
Create a similar http handler to {{AggregatingSubtasksMetricsHandler}}, but one
that would aggregate metrics per task, from all of the job vertices. The new
handler would only take {{JobID}} as a parameter. So that Web UI can in one RPC
obtain {{max(isBackPressureRatio)}} / {{max(isCausingBackPressureRatio)}} per
each task in the job graph.
This is related to FLINK-14712, where
was:Create a similar http handler to {{AggregatingSubtasksMetricsHandler}},
