Kevin,

Important stuff in the Matterhorn server is kept in a variety of places
including the filesystem, the database and the Solr index.

My impression (and I'm not a developer) is that currently the most important
store is the Solr index followed by the file system. The database certainly
has some useful information in it, but appears to be used only by a subset
of the system.

Consequently, choice of a database is not so critical, and either deployment
would work well.
