Damian Guy created KAFKA-5804:
---------------------------------

             Summary: ChangeLoggingWindowBytesStore needs to retain duplicates when writing to the log
                 Key: KAFKA-5804
                 URL: https://issues.apache.org/jira/browse/KAFKA-5804
             Project: Kafka
          Issue Type: Bug
            Reporter: Damian Guy
            Assignee: Damian Guy


The {{ChangeLoggingWindowBytesStore}} needs to have the same duplicate retaining logic as {{RocksDBWindowStore}} otherwise data loss may occur when performing windowed joins.
