Zhu Zhu updated FLINK-32199: ---------------------------- Component/s: Runtime / REST > MetricStore does not remove metrics of nonexistent parallelism in > TaskMetricStore when scale down job parallelism > ----------------------------------------------------------------------------------------------------------------- > > Key: FLINK-32199 > URL: https://issues.apache.org/jira/browse/FLINK-32199 > Project: Flink > Issue Type: Bug > Components: Runtime / Metrics, Runtime / REST > Affects Versions: 1.17.0 > Reporter: Junrui Li > Assignee: Junrui Li > Priority: Major > Labels: pull-request-available > Fix For: 1.18.0, 1.16.3, 1.17.2 > > > After FLINK-29615, FLINK will update the subtask metrics store when scaling > down parallelism. However, task metrics are added in the form of > "subtaskIndex + metric.name" or "subtaskIndex + operatorName + metric.name". > Users will be able to find many redundant metrics through > JobVertexMetricsHandler, which will be very troublesome for users. -- This message was sent by Atlassian Jira (v8.20.10#820010)
