Hello . I have a kafka broker 2.4.0 running with below message format setting both in broker and topic.
# Broker configuration inter.broker.protocol.version = 2.4-IV1 log.message.format.version = 2.4 # Topic configuration message.format.version=2.4-IV1 I just checked the documentation and realized log.message.format requires -IVX after minor version. https://kafka.apache.org/documentation/#log.message.format.version How does a broker treat log.message.format.version if "-IVX" is not specified? I ended up with below code but looks like I am not looking at the right place... https://github.com/apache/kafka/blob/7f90a58b69cd0eb63ba122b41e6ef6195b0a5d98/core/src/main/scala/kafka/server/KafkaConfig.scala#L126 Thanks, Yu -- Yu Watanabe linkedin: www.linkedin.com/in/yuwatanabe1/ twitter: twitter.com/yuwtennis
