Summary: Provide mailbox delay metric Key: FLINK-26279 URL: https://issues.apache.org/jira/browse/FLINK-26279 Project: Flink Issue Type: New Feature Components: Runtime / Metrics Reporter: Sebastian Mattheis Related to FLINK-25414. In order to better debug Task being blocked in busy state, we can periodically enqueue a mailbox action and check how long it took for the task thread to execute such action. We can report this delay as task thread delay/mailbox delay. Would be helpful for debugging why unaligned checkpoints are taking so long to trigger/execute. -- This message was sent by Atlassian Jira (v8.20.1#820001)
