I think you are right that implementing support of topic ids in the functional layer before exposing it in the API makes sense as it provides the guarantee that offsets and metadata belong to the partitions of the right topic in case of homonyms. Now, one question is how deep we go in the integration of ids in this layer. Would you consider changing the data model authored by the group coordinator down to the `OffsetCommitValue ` as prescribed by KIP 848? -- This is an automated message from the Apache Git Service.
