GroupMetadataManager

object GroupMetadataManager

Messages stored for the group topic has versions for both the key and value fields. Key version is used to indicate the type of the message (also to differentiate different types of messages from being compacted together if they have the same field values); and value version is used to evolve the messages within their data types:

key version 0: group consumption offset -> value version 0: [offset, metadata, timestamp]

key version 1: group consumption offset -> value version 1: [offset, metadata, commit_timestamp, expire_timestamp]

key version 2: group metadata -> value version 0: [protocol_type, generation, protocol, leader, members]
