As suggested by Ismael, I've factored the increasePartitionCounts() API out of KIP-179 out into a separate KIP which hopefully can progress more quickly.
https://cwiki.apache.org/confluence/display/KAFKA/KIP-195%3A+AdminClient.increasePartitions If you've looked at KIP-179 in the last few days there's no much new to see here, but if not you should find KIP-195 a lighter read. Cheers, Tom
