0.8.1 stability
Thanks for giving the 0.8.1 release a spin! A few people have reported bugs
with delete topic <https://issues.apache.org/jira/browse/KAFKA-1310> and
also the automatic leader
rebalancing<https://issues.apache.org/jira/browse/KAFKA-1305>feature
that we released as part of 0.8.1. These features were released as
beta and were not widely tested at LinkedIn, unlike most of the stuff that
we have released in the past. As a result, more bugs are being reported on
0.8.1 that are of a rather serious nature. It is unclear how many of these
bugs might show up on 0.8.1 as more people adopt it. To mitigate the impact
and also to continue releasing stable code to our users, I'm proposing we
do a point release (0.8.1.1?) to turn off these features for the time
being. Stabilize and test these and then release these as part of 0.8.2.
Do people have any thoughts on this?
Thanks,
Neha

A point release focusing on stability would definitely be nice.
And maybe a table in a wiki marking the stability of various features
(core, replication, synchronous messageing, compaction, rebalancing,
topic create, etc), so that people don't end up in the danger zone on
prod deployments.

Thanks for this follow-up, and +1 here.
I was aware, for instance, that the newly introduced delete topic
feature in 0.8.1 is not fully ready for prime time. But IIRC I
learned about this by following the mailing list (It think it was
actually a reply of yours, Neha), and I did not see a warning/comment
in the 0.8.1 release notes directly.
On my side I'm ok with adding such beta features to a release,
although I would suggest to mark them more clearly as such (i.e.
experimental). Particularly because people may have become used to
how stable the Kafka experience typically is, so if there's a new
feature you'd blindly expect it to work flawlessly. ;-)
Best,
Michael

I am +1 on a 0.8.1.1 release ( off the 0.8.1 branch tagged) for blocking bug fixes. If we have features/improvements for 0.8.2 then we should hold them off ( with 0.9.0 providing more system changes).

Hi,
We are in the process of migrating to 0.8.1, so we haven't seen any bugs
yet, but would welcome a bugfix release if others are reporting issues.
Versioning Q: wouldn't that be 0.8.2?

Auto rebalance is already turned off in 0.8.1.
