Hello, I would like to start the discussion thread for KIP-705: https://cwiki.apache.org/confluence/display/KAFKA/KIP-705%3A+Selectively+Disable+Topology+Optimizations
The KIP is proposing an additional streams configuration that allows to selectively disable optimizations under the topology.optimization bucket. Specifically, the first optimization that can be disabled is the source-topic-as-changelog optimization. Cheers, Almog
