             Summary:  Async IO Allows Custom Action after Final Retry Failure
                 Key: FLINK-33806
                 URL: https://issues.apache.org/jira/browse/FLINK-33806
             Project: Flink
          Issue Type: Improvement
          Components: API / DataStream
            Reporter: Lu Niu


in Async IO Retry Support, if all retries fail, the record is dropped without 
any further action. However, there are user cases requiring action after the 
final retry failure occurs, e.g, log out the input or write the input data to 
an external storage.  To address this, we propose to add a new API in the 
AsyncRetryStrategy and make changes accordingly.
