Description RHOS Integration 2013-12-12 19:26:36 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/glance/+spec/no-downtime-db-migrations.

Description:

Some migrations can take a long time to finish, causing a service to be down for an unacceptable amount of time. The proposed solution is to switch to an expand, migrate, contract model where migrations occur while the services are running.
