I think that work has stalled 15:30:59 4. Project "Pod". Each project gets a dedicated hang-out / mini unconference table 15:31:06 kgriffs: AFAIK, some companies are interested in porting Marconi in production env, so it would be super cool to have an operations session 15:31:36 flwang: oz_akan_ proposed a talk on that. Maybe we can trim it to 15 minutes 15:31:46 (to get it into venue #3) 15:32:09 o/ 15:32:10 kgriffs: it would be nice, thanks 15:32:11 back 15:32:22 flwang: I think we should do a few screencasts and put them on the wiki too 15:32:42 kgriffs: good idea, I can work with oz_akan_ to make it happen 15:32:49 rock on 15:32:55 I added a note to the etherpad 15:32:59 kgriffs: because I'm trying to setup it :) 15:33:21 during Juno I want to totally rock out on our docs 15:33:28 more production deployment, more feedbacks, more stable 15:33:34 flwang: cool, let's get that recorded 15:33:40 kgriffs: love it 15:33:49 even if it just used pop-up bubbles rather than voice over, that would be super awesome 15:33:59 actually, lemme take that back. gtg again! (I started the FAQ here https://etherpad.openstack.org/p/draft-marconi-faq add comments ) 15:34:09 flaper87: ttfn 15:34:21 #link https://etherpad.openstack.org/p/draft-marconi-faq 15:34:30 speaking of docs, heh 15:34:50 alcabrera, megan_w, malini: can you help with the FAQ? 15:34:58 kgriffs: sure thing 15:35:00 flwang: you too 15:35:00 kgriffs: of course 15:35:01 sure 15:35:02 :D 15:35:30 #action core team to contribute to the FAQ 15:35:38 +1 for the FAQ, I'll help around where I can as well. 15:35:55 sriram: wooot 15:36:46 #topic review updates to the API v1.1 spec 15:36:54 darn, flaper87 is MIA again. 15:36:57 * kgriffs sad panda 15:37:15 we'll never get to have nice things. :( 15:37:20 let's review pop semantics today 15:37:26 works for me 15:37:41 "Added new "pop" semantics for claiming and deleting messages in a single request. Note that this should only be used when an application is OK with the risk of missing a message when a worker crashes." 15:38:12 so, a little background 15:38:26 this idea arose independently from two sources 15:38:49 first, was the request to add it because it would make it easier to map marconi semantics to AMQP 15:39:33 second, I actually spoke with someone who is planning to use Marconi and they requested this feature for processing certain kinds of events, and they were willing to make the durability tradeoff 15:39:57 my first stab at this was adding it to the DELETE messages operation: 15:40:01 #link https://wiki.openstack.org/wiki/Marconi/specs/api/v1.1#Delete_Multiple_Messages 15:40:26 would that be a multi-pop, kgriffs? 15:40:29 I'd like to get everyones thoughts and suggestions 15:40:45 alcabrera: yes, you can set pop=N 15:40:55 gotcha -- interesting 15:40:57 alcabrera: that was also requested by the user 15:41:02 so, my initial thoughts 15:41:09 are that this POP functionality is valuable 15:41:16 I've used a variant of it already 15:41:29 which a sort of claim and delete one at a atime 15:41:32 kgriffs: is it a new endpoint? 15:41:45 **which is a 15:42:11 flwang: no, it is adding additional semantics to the existing messages resource 15:42:46 delete-bulk? 15:42:56 or like pop-bulk? 15:43:50 yeah. basically, you can delete all messages, a few by ID, or N. In the last case, the deleted messages are returned to you, and there is a guarantee that nobody else will delete those same messages. 15:44:07 "pop specifies a certain number of messages to pop off the queue, which is equivalent to claiming and deleting those messages atomically (therefore guaranteeing once-and-only-once delivery)" 15:44:13 I think pop makes it much easier to issue a request, rather than supply a large number of ids. 15:44:39 sriram: agreed 15:44:52 o/ *catching up* 15:44:57 depends on what you are trying to do 15:44:58 vkmc: :) 15:45:01 vkmc: hi! 15:45:02 kgriffs: pop will be done in a single call ? 15:45:09 Adding a pop function certainly simplifies automation, I like that! 15:45:48 HTTP DELETE /queues/{q}/messages?ids=[1, 2, 3]&pop=3 -- what would this do? 15:46:14 does 'pop' gather from the front of the queue? 15:46:20 malini: yes, a single call. you trade off the safety of the two-phase claim+delete for improved performance/convenience 15:46:25 kgriffs: yep, what's the http url looks like? 15:46:30 alcabrera: +1 good question 15:47:18 Yeah, it may be confusing to use pop with ids 15:47:22 http DELETE marconi.example.org/queues/videos/messages?pop=10 15:47:35 if you specify both ids and pop, pop is ignored 15:47:37 But DELETE currently just returns a 204 15:47:41 you really are supposed to use one or the other 15:47:47 hmmm 15:48:07 tempts me in the direction of a new endpoint 15:48:08 we probably want to return a message & delete it 15:48:19 I'm not super happy about having the exclusive-or semantic, but this was the best I thought of so far short of coming up with a new resource 15:48:27 HTTP POST /queues/videos/pop?n=10 15:48:37 or even 15:48:42 why not just claim? 15:48:51 HTTP POST /queues/videos/messages/pop?n=10 15:49:03 HTTP CLAIM /queues/videos/pop?n=10 15:49:15 because CLAIM isn't an HTTP verb, malini. :( 15:49:24 grr.. :D 15:49:27 hehe 15:49:37 so does popping follow any order here? 15:49:46 I will drink more coffee before next meeting ;) 15:49:50 malini: because the client doesn't want to make two requests, and also this semantic may make it easier to support broker-based backends, in which case I guess we would say for those backends the two-step claim isn't available? 15:50:02 I'd love to avoid overloading endpoints. Different functionality should have a different interface. 15:50:31 well, technically, there isn't anything wrong with coming up with custom HTTP verbs, but I know people will say WAH?! if we do that. :p 15:51:12 alcabrera: mmm, noted. However, remember this isn't RPC over HTTP either. We have to work in terms of resources, and IDK that a "pop" resource makes any sense. 15:51:23 hmmm 15:51:26 fair enough 15:51:33 there may be another way, don't get me wrong 15:51:46 we just need to work within the architectural style we've chosen 15:52:15 +1 for not having a resource called pop 15:52:27 #info try to find a way to not have mutually exclusive query string params on a single resource 15:52:28 PopResource 15:52:30 heh 15:53:10 let me play with it and we can revisit next time 15:53:26 +1 15:53:49 pop most like an action, not a new resouse 15:54:14 yep 15:54:22 so i prefer to don't implement it with a new endpoint 15:54:27 yeah 15:54:31 ok, last thing - we have a couple days before rc1 is cut. 15:54:45 Let's discuss the remaining bugs in #openstack-marconi 15:54:51 #topic open discussion 15:55:10 can we start doing some retros in g+ ? 15:55:21 what we are doing well, where we can improve? 15:55:34 especially focusing around graduation 15:55:55 malini: how often would you propose? 15:56:12 every 3 weeks /month 15:56:44 milestone releases are about every 4 i think 15:56:56 that may be a natural time to do them, but may not be often enough 15:57:02 I'm partial to once a month 15:57:05 sounds like reflections :) 15:57:12 I really like the idea of a retro/reflections 15:57:13 flwang: yes :) 15:57:17 for team-marconi 15:57:31 so, +1 for retrospectives 15:57:52 +1 15:57:57 we would have two parts: (1) reflect on our development process and community 15:58:08 (2) up-periscope on graduation 15:58:15 +1 15:58:17 kgriffs: +1 15:58:22 monthly sounds good 15:58:40 +1 15:58:47 in some sense 15:58:54 flaper87 is having such a thing in two days 15:59:05 the marconi g+ hangout 15:59:07 But tht's more of an FAQ , rt? 15:59:14 it might be 15:59:16 this is for the team to reflect 15:59:23 I've lost track of the vision behind that particular hang out. >.> 15:59:31 Though, I like it. :) 15:59:34 ok, g+ is useful until we get full. Also you trade having logs for higher-bandwidth communication. 15:59:48 am ok with anything where we can talk, rather than type 15:59:55 and human-to-human voice 15:59:58 visual? 16:00:14 visual wud be nice to have, not mandatory 16:00:35 google hangouts 16:00:49 #action set up monthly v&v meetings 16:00:53 +1 16:00:54 FWIW, g+ doesn't work great past 8 people 16:00:55 flwang: has a 10 person limit 16:00:58 #action kgriffs to set up monthly v&v meetings 16:01:21 ok, let's continue this chat over in #openstack-marconi 16:01:22 we'll all hangout by malini's machine 16:01:25 ;-) 16:01:27 #endmeeting
