Hello, we'd like to ask you for clarification of our question.
We have Apache Kafka deployed in the three-nodes Azure cluster. There are three Kafka brokers, three ZooKeeper nodes and three back-end services of our app. The app uses Apache Kafka as an event store. But for some reasons we couldn't upgrade Kafka client so we still have log.message.format.version=0.9.0.0 and Kafka brokers 0.10.2. We're just considering upgrading Kafka to the version 0.11.0.1 but still we are not able to update Kafka clients to newest version (i.e. we still need to use log.message.format.version=0.9.0.0). The question: Is it completely save and without performance penalty to use new Kafka brokers 0.11.0.1 with inter.broker.protocol.version=0.11.0.1 and old log.message.format.version=0.9.0.1? I mean, is there any performance impact using older message format but new inter broker protocol?
