| d0ugal | rakhmerov: Got a question for you re: cron triggers. | 09:08 |
| rakhmerov | ok | 09:09 |
| d0ugal | rakhmerov: am I right in thinking that the most frequent cron trigger is one execution per minute? | 09:09 |
| rakhmerov | nope, it's possible to configure seconds also | 09:09 |
| d0ugal | oh, interesting | 09:09 |
| rakhmerov | you just need to use 6 time placeholders instead of 5 | 09:09 |
| d0ugal | Right | 09:10 |
| rakhmerov | and the right most becomes seconds | 09:10 |
| d0ugal | rakhmerov: related question, how do you feel about making the spacing configurable? https://github.com/openstack/mistral/blob/master/mistral/services/periodic.py#L38 | 09:10 |
| rakhmerov | I figured that some time ago and was surprised too | 09:10 |
| rakhmerov | well, I'm totally fine with that but | 09:10 |
| rakhmerov | but.. | 09:10 |
| d0ugal | rakhmerov: we are using a cron trigger, but for something that runs ever 30 mins (I think). By default it checks the database every second for triggers - that creates load for no reason. If we could configured that we could make it something more sensible like every minute (or every 10 etc.) | 09:11 |
| rakhmerov | the whole subsystem needs a serious refactoring | 09:11 |
| d0ugal | Yeah, I agree | 09:11 |
| d0ugal | but at the moment we are planning to stop using it because it is causing so much load | 09:11 |
| rakhmerov | yes | 09:11 |
| rakhmerov | that's understandable | 09:11 |
| rakhmerov | my plan was to rearchitect it based on Scheduler | 09:11 |
| d0ugal | Sounds good. | 09:12 |
| rakhmerov | which is better suitable for HA, now has configuration options etc. | 09:12 |
| d0ugal | Adding a config option would be a decent workaround for us for Queens. | 09:12 |
| rakhmerov | but Scheduler needs refactoring itself too :) | 09:12 |
| rakhmerov | d0ugal: as an intermediate step, sure, no problem | 09:12 |
| d0ugal | I wasn't sure if we could easily pass a config value in to the decorator, but I see they do in Nova: http://git.openstack.org/cgit/openstack/nova/tree/nova/compute/manager.py#n1642 | 09:12 |
| rakhmerov | but I'm just sharing my forward looking plans | 09:12 |
| d0ugal | so much refactoring to do :) | 09:12 |
| d0ugal | Great, look forward to seeing them | 09:13 |
| d0ugal | rakhmerov: I guess we need to try and do some PTG planning soon | 09:13 |
| rakhmerov | d0ugal: I sent an email about office hours | 09:13 |
| rakhmerov | hopefully we'll soon agree on time slots and will do it | 09:13 |
| d0ugal | I spotted, thanks for that. I'll reply shortly. | 09:13 |
| d0ugal | I think I can make two of the slots, most of the time :) | 09:13 |
| rakhmerov | ok | 09:14 |
| rakhmerov | yes, that was my idea ) | 09:14 |
| rakhmerov | so that everybody could cover at least two | 09:14 |
| rakhmerov | d0ugal: so as far as the Scheduler, I'm planning to get to working on it soon, 2-3 weeks maybe. Some folks at Nokia are already experimenting with new approaches to implement Scheduler | 09:15 |
| rakhmerov | at some point we'll converge with them and roll out a new upstream available solution | 09:15 |
| d0ugal | Nice, it would be good if they developed it upstream too :) | 09:16 |
| rakhmerov | yes, that's the goal | 09:17 |
| rakhmerov | they just need some enhancements urgently and have to fork | 09:18 |
| d0ugal | Right | 09:18 |

| openstackgerrit | Dougal Matthews proposed openstack/mistral master: Make the cron trigger execution interval configurable https://review.openstack.org/540785 | 09:27 |
| d0ugal | rakhmerov, apetrich ^ - I think that'll work, just about to test it now tho' | 09:35 |
| rakhmerov | ok | 09:35 |
| apetrich | d0ugal, I saw that and looks good if it works :) | 09:36 |
| openstackgerrit | Merged openstack/mistral master: Fix docs to better reflect Jinja and YAQL usage https://review.openstack.org/538148 | 09:37 |
| apetrich | d0ugal, do you think that if we set the min 0 and on 0it should disable it? | 09:38 |
| apetrich | I'm saying because of random sysadm wanting it to stop and setting it to zero and getting errors instead | 09:38 |
| d0ugal | apetrich: we have the setting to disable it already - so I wasnted to avoid duplicating that. https://github.com/openstack/mistral/blob/master/mistral/config.py#L246 | 09:40 |
| apetrich | I know It is on top of that option | 09:40 |
| d0ugal | right | 09:40 |
| d0ugal | periodic_task states that if it is negative it will disable it | 09:40 |
| d0ugal | I am not sure what 0 would do | 09:40 |
| apetrich | I was just thinking that someone wanting to disable it set enable false and set it to zero and get errors | 09:40 |
| d0ugal | https://github.com/openstack/oslo.service/blob/master/oslo_service/periodic_task.py#L53 | 09:40 |
| apetrich | but on the other hand keep the change minimal is good | 09:41 |
| d0ugal | yeah, maybe I can add that later | 09:41 |
