Hi Kafka devs, The default behavior of security.inter.broker.protocol is: "InterBrokerListenerName=ListenerName.forSecurityProtocol(securityProtocol)" . We are not aware of this behavior from the security.inter.broker.protocol comment on the latest official website of Kafka. After using this configuration, the final value of InterBrokerListenerName is the same as the value of security.inter.broker.protocol. I originally thought it would find a suitable listenerName from the listener.security.protocol.map configuration.
Jira link: https://issues.apache.org/jira/browse/KAFKA-13437 You can ignore the suggestions on the num.network.threads parameter I mentioned in Jira. I recently discovered that Mickael Maison has already proposed optimizations for this parameter. I hope everyone can actively participate in the discussion. Best Regards RivenSun
