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:
