             Summary: Truncate producer state when incrementing log start offset
                 Key: KAFKA-9105
                 URL: https://issues.apache.org/jira/browse/KAFKA-9105
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 2.4.0
            Reporter: Bob Barrett
            Assignee: Bob Barrett


In github.com/apache/kafka/commit/c49775b, we removed the 
ProducerStateManager.truncateHead method as part of the change to retain 
producer state for longer. This removed some needed producer state management 
(such as removing unreplicated transactions) when incrementing the log start 
offset. We need to add this functionality back in.
