             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{}}}).
