Subject Re: Best practice for upgrading Kafka cluster from 0.8.1 to 0.8.1.1
Date Wed, 03 Dec 2014 19:33:53 GMT
Guozhang,

We haven't enable message compression yet. In this case, what shall we do
when we upgrade to 0.8.2?  Must we launch a new cluster, redirect the
traffic to the new cluster, and turn off the old one?

Thanks!

-Yu
