Hi, I've put together what will hopefully be a not too contentious KIP to enable the setting of default configs for streams internal topics via StreamsConfig.
You can find the KIP here: https://cwiki.apache.org/confluence/display/KAFKA/KIP-173%3A+Add+prefix+to+StreamsConfig+to+enable+setting+default+internal+topic+configs There is a PR here: https://github.com/apache/kafka/pull/3459 Thanks, Damian
