### [INLONG-10575][Sort] Make mysql source support report audit information exactly once Fixes #10575 ### Modifications 1. Using the checkpoint principle in Flink to modify the process, the modified flow chart is shown in Figure 1 and Figure 2. In Figure 1, the callback method of notifyCompleteCheckpoint is used to upload audit information instead of scheduled upload.Each Source/Sink will save the checkpointId of the currently ongoing checkpoint, which is nowCheckpointId in the figure. When the audit information is written to the Buffer, nowCheckpointId will be attached, indicating that the audit information is written during this ongoing checkpoint. The audit information and checkpointId are in a many-to-one relationship.  When a snapshot request is received, the current operator's nowCheckpointId is updated to (snapshot) checkpointId + 1. When all operators in a task complete the snapshot, the notifyCompleteCheckpoint method is called back. At this time, AuditBuffer uploads audit information less than or equal to checkpointId (parameters in the notifyCompleteCheckpoint method).  2. The getCurConsumedPartitions method gets the partitions assigned to the client by the tube server, including the partitions where the client has consumed data and the client has not consumed data. According to the previous logic, the offsets of the partitions that have not been consumed are not recorded. Here, the offsets of the partitions that have not been consumed are added. -- This is an automated message from the Apache Git Service.
