[jira] [Created] (FLINK-19547) Partial record clean Up after receiver task fails and restart

Yuan Mei created FLINK-19547:
--------------------------------

             Summary: Partial record clean Up after receiver task fails and restart
                 Key: FLINK-19547
                 URL: https://issues.apache.org/jira/browse/FLINK-19547
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Network
    Affects Versions: 1.12.0
            Reporter: Yuan Mei


In the mode of approximate local recovery, the problem of partial record occurs when a record is spanning over multiple buffers. If the first (several) buffers have already been sent over the network and then get lost due to the failure of the receiver task, the remaining data belonging to the same record in transition should be cleaned up.
