14:17:26 <dims> anyone from barbican around? :)
14:17:55 <gcb> 3. #link http://lists.openstack.org/pipermail/openstack-dev/2017-March/114823.html  Introduction of new driver for oslo.messaging
14:18:03 <gcb> dims: I don't think so
14:18:44 <dims> gcb : the #3 was for April 1st :)
14:19:31 <dims> EmilienM : are we going to do #2 above for pike?
14:19:48 <EmilienM> hello
14:20:07 <EmilienM> dims: I hope we can make progress
14:20:16 <gcb> dims: really?  you must be joking ,  engineers shouldn't do that
14:20:36 <dims> gcb :) it was a joke
14:20:43 <EmilienM> dims: do we have people working on it?
14:20:54 <dims> EmilienM : nope
14:21:01 <EmilienM> yeah that's the problem
14:21:10 <EmilienM> a lot of folks want it but not sure anyone is active on this task
14:21:16 <dims> EmilienM : i did some background work, got a library that works with eventlet + etcd3 - https://pypi.python.org/pypi/etcd3gw
14:21:32 <dims> and will be adding support in tooz to use that library
14:21:52 <EmilienM> dims: i'll check with therve, he also started something a few weeks ago
14:22:04 <dims> EmilienM : i thought bnemec may be interested and dhellmann was asking for specific details i think
14:22:07 <dims> thanks EmilienM
14:22:34 <EmilienM> ok I'll also check with Ben
14:22:58 <gcb> EmilienM, dims: that's really a useful feature, I can help review(learn etcd at the same time)
14:23:25 <dims> gcb : cool. will ping you on the review
14:23:34 <gcb> dims: sure
14:24:36 <gcb> okay, that's all update about oslo
14:24:53 <gcb> #topic Open discussion
14:25:20 <kgiusti> I've got one!
14:25:35 <kgiusti> I've been working with the Massively Distributed working group
14:25:54 <kgiusti> trying to help them scale with respect to messaging...
14:26:26 <kgiusti> We're trying to determine which backends make sense for a given deployment
14:26:54 <kgiusti> for example, why would one use ZeromMQ instead of rabbitmq?
14:27:14 <kgiusti> or kafka?  What are the deployment strategies
14:27:35 <kgiusti> ?  So I'm proposing a forum topic on this: http://forumtopics.openstack.org/cfp/details/62
14:27:44 <kgiusti> @ the boston summit.
14:27:54 <gcb> kgiusti,  the question we talked many times before :-)
14:27:55 <dims> kgiusti : ++
14:28:28 <kgiusti> I'd like to work towards some recommendations, backed up with data ideally :)
14:28:32 <gcb> kgiusti, ++
14:29:16 <kgiusti> TBH - I'm not really an expert in some of these drivers, so it would be great if the other driver specialists would weigh in here and help out.
14:29:51 <kgiusti> In any case, something to think about.
14:31:14 <gcb> kgiusti,  we use rabbit backend in production, would like to help if I can :-)
14:31:52 <kgiusti> gcb great thanks - also anyone interested in joining the MDWG discussions that would be great.
14:32:28 <kgiusti> fyi: https://wiki.openstack.org/wiki/Massively_Distributed_Clouds
14:33:15 <gcb> kgiusti, you got my questions, haha, just want to ask lol
14:33:43 <kgiusti> One other topic:
14:34:25 <kgiusti> I've got a proposal accepted @ boston to talk about "dual messaging backends"
14:34:45 <kgiusti> e.g.: rabbitmq for notifications, Zeromq for rpc, etc...
14:35:16 <kgiusti> If anyone would like to join the presentation and help out, just ping me on irc.  Thanks.
14:35:36 * jungleboyj 's head explodes
14:35:57 <kgiusti> Wed 10th 11 am
14:36:08 <kgiusti> jungleboyj: yeah that happens alot.
14:36:13 <jungleboyj> I have a hard enough time understanding the setup with one message service.  :-)
14:36:30 <jungleboyj> kgiusti: Ok, glad it isn't just me.
14:36:58 <kgiusti> :)  hopefully with Triple0, etc, support it will be a great bit less painful than it is now.
14:37:38 <kgiusti> jungleboyj: but there are tests in CI (heat I believe) that are doing this atm.
14:37:56 <jungleboyj> Ok, that is good.
14:38:17 <gcb> jungleboyj,  just checkout #link http://forumtopics.openstack.org/cfp/details/79 , bring all of your pain points about oslo  there
14:38:19 <kgiusti> but it would be great if we could get kafka, zeromq folks to join the preso
14:39:17 <gcb> kgiusti, agree
14:39:23 <jungleboyj> kgiusti:  Thanks.
14:40:27 <kgiusti> thanks everyone.
14:41:08 <gcb> kgiusti, please go ahead, hope I didn't disturb you :-)
14:41:34 <kgiusti> gcb: not at all - that's all I have for now.
14:42:30 <gcb> okay,  anyone has other things to discuss ?
14:44:17 <gcb> I think we can call it a meeting, and back to openstack-oslo to discuss any oslo stuff
14:45:16 <gcb> BTW, Chinese have 3 days holiday,  I will be back on April 5
14:45:31 <gcb> thanks everyone
14:46:17 <jungleboyj> Sounds good.  Thanks gcb
14:46:21 <jungleboyj> Have a good vacation.
14:47:03 <gcb> jungleboyj,  thanks, have a nice day
