Subject Re: Any gotchas upgrading to 0.9?
Date Tue, 01 Dec 2015 16:57:02 GMT
Also I remember reading (can't find now) something about default traffic
quotas. I'd hope the default quotas are very large (infinite?) and not
small so that compatibility is maintained. It would be very unfortunate if
some of our traffic was throttled because of the upgrade because of magic
defaults. For example we have a certain cluster dedicated to serving a
single important topic and we'd hate for it to be throttled because of
incorrect defaults.
