             Summary: Separate Internal and External traffic
                 Key: KAFKA-4565
                 URL: https://issues.apache.org/jira/browse/KAFKA-4565
             Project: Kafka
          Issue Type: Bug
            Reporter: Ismael Juma
            Assignee: Ismael Juma


During the 0.9.0.0 release cycle, support for multiple listeners per broker was introduced (KAFKA-1809). Each listener is associated with a security protocol, ip/host and port. When combined with the advertised listeners mechanism, there is a fair amount of flexibility with one limitation: at most one listener per security protocol in each of the two configs (listeners and advertised.listeners).

In some environments, one may want to differentiate between external clients, internal clients and replication traffic independently of the security protocol for cost, performance and security reasons. See the KIP for more details: https://cwiki.apache.org/confluence/display/KAFKA/KIP-103%3A+Separate+Internal+and+External+traffic
