I think I'm to blame (apologies!) for suggesting that one driver was preferred over the other (that was my understanding a few weeks ago, based on test coverage). However, test coverage has since improved and I think people are having good experience with the SQL driver.
The two methods are *not* functionally identical. The file-based driver is simple and high-performance, and the sql-based driver provides flexibility and API/CLI administration. I've just proposed a review to clarify each option in the http://keystone.openstack.org/configuration.html docs: https://review.openstack.org/#change,5820 As well as a separate review to change the default backend to SQL, since most users are looking for the CLI management commands out of the box: https://review.openstack.org/#change,5821 -Dolph On Mon, Mar 26, 2012 at 8:29 AM, David Kranz <[email protected]> wrote: > There seems to be an unfortunate difference in opinion out there about > whether the keystone endpoints should be defined using templates (devstack) > or keystone calls (ubuntu).
