We're already chatting - as is quite a bit further
along we'll focus on taking this codebase f orward, with probably the
addition of postgresql support if we need it.


If anyone is interested, we'll also be covering this in todays charms IRC
meeting at 1700 UTC in #openstack-meeting-4 - I'm pretty confident we can
get to a reasonable v1 set of changes quickly (i.e. this week) for
integration of gnocchi into the openstack charm set!

Yup - there is some detail to work out here; gnocchi o nly has context from
OpenStack Mitaka onwards so this does limit the scope of any support; as
the charms have a series aligned templating system, we can leave the older
style configuration intact and just move forward on the newer releases with
the transport_url option + the required notification driver configuration.
