             Summary: Restricting access of commit for consumer member
                 Key: KAFKA-9421
                 URL: https://issues.apache.org/jira/browse/KAFKA-9421
             Project: Kafka
          Issue Type: Improvement
            Reporter: Boyang Chen


Currently for during each generation, the partition ownership should be unique 
for members, which infers we shouldn't allow multiple consumers committing to 
the same partition. This logic is currently not supported on broker side, and 
we should discuss whether this is needed and useful.
