Hi, I am also very excited to see this discussion, because I also implemented the "federation model" based on the kafka-0.10.2.1 version before in company and got benefits from going online. It solves the problem of seamlessly migrating the bytesIn/bytesOut of a topic to another kafka cluster without the client being aware. Therefore, it includes the cross-cluster synchronous topic data mentioned in this discussion, and ensures the consistency of the offset. It also provides the global coordinator service to ensure the consistency of the group offset, and the metadata service to ensure that the client is visible of the real traffic cluster of the topic. So I am very excited to see that the community has finally discussed this feature, and I especially hope to participate in the development and reviewer of this feature as a co-author.
