Hi Jan, Thanks for the question and interest in the KIP. I'll be participating in this discussion from the authors' side as well. KIP-E has been published today as https://cwiki.apache.org/confluence/display/KAFKA/KIP-1181%3A+Metadata+Rack+Awareness+for+Diskless+Topics and the proposal there is a little different from KIP-1123. Please take a look.
