[openstack-dev] [Octavia] Minutes from 8/13/2014 meeting

I agree pretty strongly with Brandon's and Doug's comments as well.

And I did want to clarify that I certainly don't hate the Neutron cores
either. I feel like we (those working on Neutron LBaaS and the Cores) made
commitments to each other both at the Atlanta summit and the mid-cycle
hackathon, including taking on additional work we otherwise wouldn't have
done in order to work with the Neutron team in good faith. I feel like we
upheld our end of the deal, but without getting the reviews we need to get
into Juno, and with LBaaS becoming the poster child (or proof of concept,
or guinea pig, depending on your level of cynicism) for projects that
should go into Neutron Incubator...  well, here we are about to hit Juno-3
and there's essentially zero chance we're going to get in.

All that is to say, I think the cores we've been working with embarked on
this in good faith, but unexpected happenings in the Neutron community have
necessitated the events as they are happening. I think I understand *why*
things have happened as they have, but I can't help but feel like our team
was betrayed here. And it's certainly not going to be any easier to
convince our bosses that our time working on Neutron LBaaS over the last
few months was well spent when the features and changes we need are no
closer to becoming part of the official, accepted code base. (Heck, if
Brandon is the voice of Optimism in our defacto team, then you can call me
the voice of Skepticism in it:  It's also conceivable that with the extra
complication of neutron-incubator graduation being worked through, it is
likely that we will not see our changes get into Kilo either!)

I do hope that they take our previously voiced concerns about
neutron-incubator very seriously (particularly the ones about moving
Neutron LBaaS v1 into incubator, and taking meaningful, tangible steps to
solve the core reviewer bandwidth problem that I think is the *real* reason
it takes so long to get major changes into Neutron.) At this time, though,
I feel like prudence demands we spend time making Octavia happen--  after
all, we can only go through so many cycles where we effectively have
nothing to show for our work before we'll all be out of our jobs. :/

On joining the weekly meetings and otherwise contributing:

We'd love to have you attend Salvatore! If you (or anyone else interested)
are free at 20:00 UTC on Wednesdays, shoot me a note and I can get you the
webex connection details.

If you're not able to make it to these--  well, in any case we mean for
in-depth discussions to happen either via the mailing list or IRC (we're in
#openstack-lbaas ). Right now the meetings are mostly being used to answer
questions, raise concerns and drive consensus without usually going into
novel discussions that weren't already started via the mailing list or IRC.

On holding these meetings via IRC:

Actually, we did discuss each of the points you brought up Salvatore. And
yes Doug, a voice meeting with variable and sometimes high latency is going
to naturally prefer those with more boorish communication styles (like me)
who (allegedly accidentally) end up walking over the voice of people who
are either quieter or prefer to wait for pauses to communicate. (Sorry
about that.) The plus-side of voice and video communication is much higher
bandwidth (even for people like me who type quite quickly), and many kinds
of human communication are much more effective when voice and video are
used versus simple text. (

We did put it up for an informal vote and the consensus was to keep doing
the video meetings for the time being (especially while we're still
bootstrapping this project). But I did point out that asking the people who
joined the video meeting whether they wanted to keep doing video meetings
might simply be a form of confirmation bias. ;)
