It's a little bit different from what I can see.  The ephemeral 
databases go away on device reboot, and you can seemingly configure 
anything you want in them (versus dynamic databases, which are limited 
to just a few BGP related configs, from what I see).

They seem to be a full overlay config as well.

For example, the main config has:

set protocols bgp group to_AMSIX neighbor 80.249.211.140 import AMSIX-IX-in

and the ephemeral config has :

set protocols bgp group to_AMSIX neighbor 80.249.211.140 import 
ps-AS13335-v4-in
set protocols bgp group to_AMSIX neighbor 80.249.211.140 import AMSIX-IX-in

and then if we look at show bgp neighbor:

Import: [ ps-AS13335-v4-in AMSIX-IX-in ]

I don't think you could do this with the dynamic db, at least according 
to the documentation.
