11:00:15 efried alex_xu Good evening, you still around?
11:13:42 openstackgerrit OpenStack Proposal Bot proposed openstack/os-vif master: Updated from global requirements https://review.openstack.org/511035
11:51:48 efried cdent Ready for a lunchtime spitballing session?
11:51:59 cdent one moment please caller
11:55:59 openstackgerrit Eric Fried proposed openstack/nova master: Include /resource_providers/uuid/allocations link https://review.openstack.org/499826
11:58:37 cdent efried: k, was just finishing up an email about correcting a draft of my will. what’s up?
11:58:52 efried heh, that seems fairly important.
11:59:21 efried cdent I was reviewing your 'limit allocation candidates' patch and it occurred to me that the 'randomize' conf setting should apply whether we're limiting or not.
11:59:40 efried Left a comment to that effect, but wanted to brainstorm with you and see if you agree.
12:00:43 cdent I’m guessing you’re thinking: if we’re going to randomize at all, it should be whether there is a limit or not, and if it going to happen it should happen in one place, not in multiple clients?
12:00:59 efried cdent Javol
12:01:10 efried Were we randomizing from the scheduler somehow?
12:01:27 cdent we were leaving todos about needing to decide if/how to select from too many candidates
12:02:10 efried Oh, then yeah, IMO this is that decision, and this is the sensible place to do it.
12:02:18 cdent the belief is that most people will not want to randomize, as that will tend to spread, which is apparently not a common desire (I don’t actually know how certain or true that is)
12:02:35 cdent yeah, I think you’re right.
12:03:06 efried Okay, that answers the other point of whether we should default to True - sounds like no.
12:03:49 cdent I think we should, but apparently that would change behaviors in an unacceptable way
12:04:10 efried Even though the order of candidates is undefined today.
12:04:12 cdent and bias in favor of the user rather than ops or something
12:04:22 cdent it is undefined, but semi-static
12:04:34 efried But if we've ascertained that the general preference is pack vs. spread, we should indeed preserve that behavior.
12:04:40 cdent the database will do its own ordering, with some bias
12:04:55 efried Which will be deterministic, but not really predictable by a human.
12:05:26 cdent however, I expect that the complexity of the queries thes days, and the inclusion of usage informatin throws off a lot of that ordering
12:05:51 cdent but it was deemed an important part of the plan when discussed in denver
12:06:02 efried cdent Also, just a point of curiosity, were we planning to use the limit param from the scheduler? I would think so - it should be fairly simple to come up with a number that would always give us enough candidates. And that number would be pretty small, too, like on the order of a dozen or so.
12:06:17 cdent so I reckon the change is fairly simple: if not limit and conf thing true: random.shuffle(allocs)
12:06:45 cdent efried: yes, that’s eventual hope: that the scheduler would retrieve much less data
12:07:21 cdent some math of needed instances X needed alternates X fudge factor
12:07:41 efried Yeah, cause at this point we haven't chosen a cell yet, right?
12:08:11 efried Once we pick a cell we get down to three alternates (per instance)
12:08:13 cdent the cell is chosen based on the “claimed” destination
12:08:25 cdent three isn’t static is it, that comes from conf, yeah?
12:08:32 efried edleafe ^ ?
12:08:52 efried In any case, that would make the math simple. #alternates * #instances
12:08:54 cdent needed x retries x cells
12:09:15 efried Okay. Not critical right now, but it's on the radar - cool.
12:09:34 cdent if we don’t include X cells, we may not end up with enough space to pick from
12:09:48 cdent yeah, on the radar - cool
12:09:54 cdent glad you though of that
12:11:10 cdent efried: if you want another thing to do with with your copious free time, I’ve got some microversion_parse changes that need some thinking about and there are few people who are aware of all the bits of context, you might be a good reviewer: https://review.openstack.org/#/c/496212/ and https://review.openstack.org/#/c/495356/
12:11:33 cdent no rush on that (at all) just stuff I’m sort of rolling around for the cool radar
12:11:59 efried For my part, I got started on numbered groupings in GET /allocation_candidates
12:12:13 efried We've got like a 5-way race to placement microversion 1.11.
12:13:28 cdent Is it only 5?
12:44:43 efried dtantsur|brb I'd like to be invited to the discussion of ironic traits vs. configurables if possible. Thanks!
12:47:49 openstackgerrit Jan Zerebecki proposed openstack/nova master: Only log not correcting allocation once per period https://review.openstack.org/508262
12:48:52 openstackgerrit jichenjc proposed openstack/nova master: Remove duplicate error info https://review.openstack.org/510719
12:56:52 cdent maybe we should put traits in etcc and make them watchable
