Can you be more specific? I'm having a brain fart here and not
remembering what you are referring to with respect to the nova_api DB.

I'm pretty sure you were in the room in YVR when we talked about how
operators were going to do the database migration and were mostly OK
with what was discussed, which was a lot will just copy and take the
downtime (I think CERN said around 10 minutes for them, but they aren't
a public cloud either), but others might do something more sophisticated
and nova shouldn't try to pick the best fit for all.
I'm definitely interested in what you do plan to do for the database
migration to minimize downtime.
+openstack-operators ML since this is an operators discussion now.
