Hi @hudeqi. Thanks for the patch. I would like to better understand it. My first question is how would Flink commit Flink with a generationId equal to -1? The generation of the group is only managed by the group. It is not possible to alter it from an external system. The -1 passed in the offset commit request is only used for validation purposes. The reason why we don't write a tombstone in this case is because the group was never materialized in the log if it stayed at generation 0. I am not sure it is a worthwhile optimization though. -- This is an automated message from the Apache Git Service.
