Hi, If you want to see or test the my current idea of the implementation of this KIP, you can check it out in my repo: https://github.com/jukkakarvanen/kafka/compare/trunk...jukkakarvanen:KAFKA-8233_InputOutputTopics
After my test with KPI-451 I do not see need for add methods for Iterables, but waiting Patrick's clarification of the use case.
