Hi, all

I submitted a change: https://review.openstack.org/#/c/443964/
but seems like it reached a point which requires an additional discussion.

I had a few proposals, it's increasing period to 12 hours instead of 4
for start, and to leave it in regular periodic *low* precedence.
I think we can start from 12 hours period to see how it goes, although I
don't think that 4 only jobs will increase load on OVB cloud, it's
completely negligible comparing to current OVB capacity and load.
But making its precedence as "low" IMHO completely removes any sense
from this pipeline to be, because we already run experimental-tripleo
pipeline which this priority and it could reach timeouts like 7-14
hours. So let's assume we ran periodic job, it's queued to run now 12 +
"low queue length" - about 20 and more hours. It's even worse than usual
periodic job and definitely makes this change useless.
I'd like to notice as well that those periodic jobs unlike "usual"
periodic are used for repository promotion and their value are equal or
higher than check jobs, so it needs to run with "normal" or even "high"
precedence.

Yeah, it makes no sense from an OVB perspective to add these as low priority jobs. Once in a while we've managed to chew through the entire experimental queue during the day, but with the containers job added it's very unlikely that's going to happen anymore. Right now we have a 4.5 hour wait time just for the check queue, then there's two hours of experimental jobs queued up behind that. All of which means if we started a low priority periodic job right now it probably wouldn't run until about midnight my time, which I think is when the regular periodic jobs run now.


Thanks

        The request doesn't strike me as contentious/controversial. Why not
        just propose your addition to the zuul/layout.yaml file in the
        openstack-infra/project-config repo and hash out any resulting
        concerns via code review?

    Sounds good to me.
    We thought it would be nice to walk through it in an email first :)

    Thanks
