Zhu Zhu updated FLINK-27710: ---------------------------- Description: 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> {{}}}}(<{{{}subtaskIndex>+1{}}}/<{{{}vertex parallelism>{}}}) {{#<attemptNumber>}} (graph: <{{{}short ExecutionGraphID>, vertex: <{}}}{{{}JobVertexID>{}}}) " and avoid directly display the {{{}ExecutionAttemptID{}}}. This can increase the log readability. was: 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.

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{}}}). > 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 > Assignee: Zhu Zhu > Priority: Major > Labels: pull-request-available > 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.
