URL: https://github.com/apache/iceberg/issues/9089#issuecomment-1813965148

   Its Flink Version 1.13.2.   Currently it would be complicated to update 
Iceberg version as the application has a lot of state.
   Checkpoints are being triggered and finished as scheduled, however there are 
no commits happening to the tables. And when a commit does happen, it happens 
at random times.  The issue started to appear after scaling the application's 
parallelism.   How can i detect if its a concurrent commit.  In the logs i 
can't find any exception, or error, or the Flink Application restarting. Dont 
want to update Iceberg version and Flink Version without finding the root cause.
   
   Its a Flink application that its writing to multiple Iceberg Tables in S3
   
   In logs I am able to see:
   - 
org.apache.flink.streaming.runtime.tasks.SubtaskCheckpointCoordinatorImpl.notifyCheckpointComplete
   - Discarding local task state snapshot TaskOperatorSubtaskStates
   - Start to flush snapshot state to state backend, table:
