Is the DB the limiting factor of openstack performance ? De we have hard evidence of this ? We need numbers before acting otherwise it will be an endless discussion. When I look at the number of race conditions we had/have in OpenStack, it seems scary to remove the FK in the DB. FK look like a "guardian" to me and we should aim at enforcing more consistency/integrity, not the contrary. Also, this is an open source project with contributors with different skills and experience (beginners, part time contributor etc.). Maybe this is something to also consider. Jordan
