However there are 2 > problems we found: > # The JobManager is required to aggregate metrics from all task managers. > When the metric cardinality is quite high, this process can trigger a > JobManager Full GC and slow response time. > # Flink user cases in prod usually have their own dashboard to view metrics. > so this feature sometimes is not useful. > In light of this, we propose to add option to disable this feature. -- This message was sent by Atlassian Jira (v8.20.10#820010)
