Zhu Zhu created FLINK-27710: ------------------------------- Summary: Improve logs to better display Execution Key: FLINK-27710 URL: https://issues.apache.org/jira/browse/FLINK-27710 Project: Flink Issue Type: Improvement Components: Runtime / Coordination, Runtime / Task Affects Versions: 1.16.0 Reporter: Zhu Zhu Fix For: 1.16.0
Currently, an execution is usually represented as "{{{}job vertex name{}}} ({{{}subtaskIndex+1{}}}/{{{}vertex parallelism{}}}) ({{{}attemptId{}}})" in logs, which may be redundant after this refactoring work. With the change of FLINK-17295, the representation of Execution in logs will be redundant. e.g. the subtask index is displayed 2 times. Therefore, I'm proposing to change the format to be "{{{}job vertex name{}}} ({{{}short ExecutionGraphID{}}}:{{{}JobVertexID{}}}) ({{{}subtaskIndex+1{}}}/{{{}vertex parallelism{}}}) ({{{}#attemptNumber{}}})" and avoid directly display the {{{}ExecutionAttemptID{}}}. This can increase the log readability. Besides that, the displayed {{JobVertexID}} can also help to distinguish job vertices of the same name, which is common in DataStream jobs (e.g. multiple {{{}Map{}}}). -- This message was sent by Atlassian Jira (v8.20.7#820007)
