Andrew Schofield commented on KAFKA-16657:
------------------------------------------
Ah, sorry for the jargon :) Apache Kafka = AK.
The latest release is Apache Kafka 3.7. This release supports KRaft and
ZooKeeper.
The release under development is Apache Kafka 3.8. This release supports KRaft
and ZooKeeper, but it's the final release that supports ZooKeeper.
The following one is Apache Kafka 4.0. This release only has KRaft.
This is why some features only work with KRaft. Soon, Kafka will be KRaft only.
> KIP-848 does not work well on Zookeeper Mode

> Hi, Kafka Team.
> I am testing the new rebalance protocol of KIP-848. It seems that the KIP-848
> protocol works well in KRaft mode. However, KIP-848 protocol does not work
> well in `Zookeeper` mode.
>
> I have created two versions of docker-compose files for Zookeeper Mode and
> KRaft Mode. And I tested KIP-848 using the same consumer code and settings.
>
> In KRaft Mode, the consumer received the assignment correctly. However, an
> error occurred in Zookeeper Mode.
>
> *Is KIP-848 supported in Zookeeper mode? or only KRaft is supported?*
>
> FYI, This is the code I used.
> * ZK docker-compose:
> https://github.com/chickenchickenlove/kraft-test/blob/main/docker-compose2/docker-compose.yaml
> * ZK Result:
> https://github.com/chickenchickenlove/kraft-test/blob/main/docker-compose2/README.md
> * KRaft docker-compose:
> https://github.com/chickenchickenlove/kraft-test/blob/main/docker-compose3/docker-compose.yaml
> * KRaft Result:
> https://github.com/chickenchickenlove/kraft-test/blob/main/docker-compose3/README.md
> * Consumer code:
