[jira] [Created] (FLINK-36614) mysql cdc will be stuck when the ChangeEventQueue is full at snapshot consume phase

Youle created FLINK-36614:
-----------------------------

             Summary: mysql cdc will be stuck when the ChangeEventQueue is full at snapshot consume phase
                 Key: FLINK-36614
                 URL: https://issues.apache.org/jira/browse/FLINK-36614
             Project: Flink
          Issue Type: Bug
          Components: Flink CDC
    Affects Versions: cdc-3.1.1
            Reporter: Youle
         Attachments: image-2024-10-28-20-21-11-112.png

Reason: The ChangeEventQueue may get too many events because of little delay of network.
The ChangeEventQueue is writen data to be full before it is called to disconnect the binarylog client connection.


Solve: The data  is not necessary when the the task is not running. I think we can avoid the ChangeEventQueue to be full by adding these code lines.

Is it right to work in this way? Can anyone check this?
