zlzhang0122 closed FLINK-19876. ------------------------------- Resolution: Won't Fix > Latency metrics can merge chain task latency metrics to reduce the number of > latency metrics > --------------------------------------------------------------------------------------------- > > Key: FLINK-19876 > URL: https://issues.apache.org/jira/browse/FLINK-19876 > Project: Flink > Issue Type: Improvement > Components: Runtime / Metrics > Reporter: zlzhang0122 > Priority: Major > > In latency metrics report, each operator will report themselves latency > metics, but actually the communication between chain operators which in one > task is very fast and the latency can be ignored.So maybe we can merge the > chain operator latency metrics into one to decrease the number of it. > For example, if source operator and downstream flat Map operator has been > chained, now it will report the latency metrics separately, while we can > merge it and make them report their latency metrics only once. -- This message was sent by Atlassian Jira (v8.3.4#803005)
