[openstack-dev] [Keystone] SQLite support (migrations, work-arounds, and more), is it worth it?

I am looking forward to the Liberty cycle and seeing the special casing we do for SQLite in our migrations (and elsewhere). My inclination is that we should (similar to the deprecation of eventlet) deprecate support for SQLite in Keystone. In Liberty we will have a full functional test suite that can (and will) be used to validate everything against much more real environments instead of in-process “eventlet-like” test-keystone-services; the “Restful test cases” will no longer be part of the standard unit tests (as they are functional testing). With this change I’m inclined to say SQLite (being the non-production usable DB) what it is we should look at dropping migration support for SQLite and the custom work-arounds.

Most deployers and developers (as far as I know) use devstack and MySQL or Postgres to really suss out DB interactions.

I am looking for feedback from the community on the general stance for SQLite, and more specifically the benefit (if any) of supporting it in Keystone.
