> * What should we do about nova calling the placement db, like in > > [nova-manage](https://github.com/openstack/nova/blob/master/nova/cmd/manage.py#L416) This should be purely a placement-side migration, nah? > and > > [nova-status](https://github.com/openstack/nova/blob/master/nova/cmd/status.py#L254). For others' reference, Chris and I have been discussing this [1] in the spec review that was prompted by the above. As of the last episode: a) we're not convinced this status check is worth having in the first place; but if it is, b) the algorithm being used currently is pretty weak, and will soon be actually bogus; and c) there's a suggestion for a "better" (if not particularly efficient) alternative that uses the API instead of going directly to the db. -efried [1] https://review.openstack.org/#/c/600016/3/specs/stein/approved/list-rps-having.rst@49
