Kafka protocol OffsetCommit message
Request versions summary:
- Version 1 adds timestamp and group membership information, as well as the commit timestamp.
- Version 2 adds retention time. It removes the commit timestamp added in version 1.
- Version 3 and 4 are the same as version 2.
- Version 5 removes the retention time, which is now controlled only by a broker configuration.
- Version 6 adds the leader epoch for fencing.
- version 7 adds a new field called groupInstanceId to indicate member identity across restarts.
- Version 8 is the first flexible version.
- Version 9 is the first version that can be used with the new consumer group protocol (KIP-848). The request is the same as version 8.
Response versions summary:
- Versions 1 and 2 are the same as version 0.
- Version 3 adds the throttle time to the response.
- Starting in version 4, on quota violation, brokers send out responses before throttling.
- Versions 5 and 6 are the same as version 4.
- Version 7 offsetCommitRequest supports a new field called groupInstanceId to indicate member identity across restarts.
- Version 8 is the first flexible version.
- Version 9 is the first version that can be used with the new consumer group protocol (KIP-848). The response is the same as version 8 but can return STALE_MEMBER_EPOCH when the new consumer group protocol is used and GROUP_ID_NOT_FOUND when the group does not exist for both protocols.
