Hello Colin, Thank you for the response! 1. I have attached the compatibility matrix in the KIP under the section Compatibility, Deprecation, and Migration Plan. 2. I believe the answer to how many bridge releases (for Kafka) will be needed to upgrade from 2.0 to 4.0 based on the compatibility ma

Re: [VOTE] KIP-902: Upgrade Zookeeper to 3.8.1

I'm +1 for this change, but we should do it early in the release cycle. Perhaps 3.6.0 is the right release target. That should buy us enough time for users to migrate to kraft mode. Ismael On Mon, Mar 20, 2023 at 10:12 AM Divij Vaidya wrote: > Hey Colin > > Thank you for your feedback. In addit

Hey Colin Thank you for your feedback. In addition to what Christo mentioned above, I have tried to provide answers to your questions below. Also, for some context, we have had some conversation about the upgrade in the comments of this PR

Hello Colin, Thank you for taking the time to review the proposal! I have attached a compatibility matrix to aid the explanation below - if the mailing system rejects it I will find another way to share it. For the avoidance of doubt, I am not proposing to drop support for rolling upgrade from o

Hi, I'm struggling a bit with this KIP, because dropping support for rolling upgrades from old Kafka versions doesn't seem like something we should do in a minor release. But on the other hand, the next Kafka release won't have ZK at all. Maybe we should punt on this until and unless there is a

Re: [VOTE] KIP-902: Upgrade Zookeeper to 3.8.1

Thanks for the KIP Christo. Having Zk 3.6 reach EOL in Dec 2022 is a good enough reason to upgrade, hence I completely agree with the motivation. Your experiments have demonstrated that the new version of Zk is stable at scale and the backward compatibility risks are acceptable since Apache Kafka
