Re: [DISCUSS] Apache Kafka 4.0.0 release

We discovered a regression in a specific Kafka Streams API. I filed a ticket here: https://issues.apache.org/jira/browse/KAFKA-18917 and a fix here: https://github.com/apache/kafka/pull/19089. The fix is small, I would suggest we include this fix in 4.0. On Tue, Mar 4, 2025 at 12:19 PM David Jacot

Re: [DISCUSS] KIP-1134: Virtual Clusters in Kafka

Hi, I'll answer your questions below. 1. Sure, I amended the KIP with a diagram. 2. Topics scale out as they did before, there will be no changes. One can increase the replication factor or partition count as they did before. 3. Virtual clusters aren't physical entities, there won't be any broker

Re: [DISCUSS] KIP-1136: Make ConsumerGroupMetadata an interface

Hi, I think it should be sufficient to just state in the JavaDocs of the new interface, that the interface is not intended to be implement by users, and point to the Consumer method that returns it. To me, the main thing is really, that currently user can call `new` what makes it easy to do

Re: [DISCUSS] KIP-1124: Providing a clear Kafka Client upgrade path

hi Kuan-Po Q1: in the "Kafka Connect:" section, the word "clients" should be replaced by "connect", right? Q2: Additionally, could you add a brief description explaining why the bridge version used by Connect is "3.8.x - 3.9.x"? This conflicts with the "API compatibility" section. Best, Chia-Ping
