Subject Re: Running Kafka 1.0 binaries with inter.broker.protocol.version = 0.10
Date Wed, 06 Dec 2017 17:39:42 GMT
Thanks Manikumar for replying. One more query regarding your first reply

What if I set both inter.broker.protocol.version & log.message.format.version
to 0.10 and update the binaries? How is Kafka supposed to behave & what we
are going to miss?
