Hi Everyone, One of the pre-requisites we have for supporting multiple security protocols (SSL, Kerberos) is to support them on separate ports.
This is done in KAFKA-1684 (The SSL Patch), but that patch addresses several different issues - Multiple ports, enriching the channels, SSL implementation - which makes it more challenging to review and to test. I'd like to split this into 3 separate patches: multi-port brokers, enriching SocketChannel, and the actual security implementations. Since even just adding support for multiple listeners per broker is somewhat involved and touches multiple components, I wrote a short design document that covers the necessary changes and the upgrade process: https://cwiki.apache.org/confluence/display/KAFKA/Multiple+Listeners+for+Kafka+Brokers Comments are more than welcome :) If this is acceptable, hope to have a patch ready in few days.
