Compatibility with Apache Kafka 4.0 #1360
Comments

I believe kafka-go will work with Kafka 4.0 in general because Kafka 2.x protocol support was added to kafka-go and that is not going away with Kafka 4. You will not get the very latest protocol versions with kafka-go yet, but the existing protocols should work, generally speaking. It appears that even if Apache removed support for all <2.1 protocol versions, kafka-go would still function similarly to today. We don't yet have plans to test Kafka 4 as it is still most likely 1-2 months from release. |

Thanks for the response. Let me ask a more concrete question, the following file seems to show V1, but not V2+. While KIP-896 removes both V0 and V1 for the JoinGroup request. Won't that be an issue? https://github.com/segmentio/kafka-go/blob/main/joingroup.go |
Apache Kafka 4.0 will remove a number of very old protocol API versions as specified by KIP-896. I was trying to understand if this client will work correctly with it and it was not clear, particularly when it comes to the consumer group apis.
So, I thought it would be simplest to ask the project maintainers. :) Note that the 4.0 branch of Apache Kafka contains the KIP-896 changes in case you would like to test your client.
