Subject Re: [DISCUSS] KIPs

Thanks Jay for kicking this off! I think the confluence page you wrote up
is a great start.

The KIP makes sense to me (at a minimum) if there is going to be any
"breaking change". This way Kafka can continue to grow and blossom and we
have a process in place if we are going to release a thorn ... and when we
do it is *CLEAR* about what and why that is. We can easily document which
KIPs where involved with this release (which I think should get committed
afterwards somewhere so no chance of edit after release). This approach I
had been thinking about also allows changes to occur as they do now as long
as they are backwards compatible.  Hopefully we never need a KIP but when
we do the PMC can vote on it and folks can read the release notes with
*CLEAR* understanding what is going to break their existing setup... at
least that is how I have been thinking about it.

Let me know what you think about this base minimum approach... I hadn't
really thought of the KIP for *ANY* "major change" and I have to think more
about that. I have some other comments for minor items in the confluence
page I will make once I think more about how I feel having a KIP for more
than what I was thinking about already.

I do think we should have "major changes" go through confluence, mailing
list discuss and JIRA but kind of feel we have been doing that already ...
if there are cases where that isn't the case we should highlight and learn
from them and formalize that more if need be.
