> will a kafka client in version 4 be able to talk to a kafka 3 broker? Thanks for the question @vsevel Yes, a Kafka 4.x client will be able to work with Kafka brokers >= 2.1.x. And similarly, a Kafka 4.x broker will be able to work with Kafka clients >= 2.1.x. If you decide to upgrade to the Kafka 4.0 clients to gain Java 23+ support, applications will no longer be able to contact brokers running Kafka 0.x, 1.x, or 2.0.x You can see the planned phase-out of protocol versions here: https://cwiki.apache.org/confluence/display/KAFKA/KIP-896%3A+Remove+old+client+protocol+API+versions+in+Kafka+4.0 -- This is an automated message from the Apache Git Service.
