[jira] [Created] (FLINK-14583) Remove progressLock from
ExecutionGraph
vinoyang created FLINK-14583:
--------------------------------
Summary: Remove progressLock from ExecutionGraph
Key: FLINK-14583
URL: https://issues.apache.org/jira/browse/FLINK-14583
Project: Flink
Issue Type: Sub-task
Components: Runtime / Coordination
Reporter: vinoyang
There is a lock object named {{progressLock}} which used to secure all access to mutable fields, especially the tracking of progress within the job. Now, the {{ExecutionGraph}} can only be accessed by a single thread at any time point. IMO, we can remove this lock.
