Boyang Chen commented on KAFKA-9421: ------------------------------------ At the moment it doesn’t seem necessary for existing use cases. Also for really advanced users, they may actually want to let their consumers work concurrently on one partition, I guess this will then become a user’s responsibility for making their customized partition assignor behave correctly. > 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 > Priority: Major > > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
