Thanks Morgan. In my embedded situation, There is no hard drive where I run the Openstack controller, keystone, and other control functions, thus, my only choice has to be to use an in-core-db (cache) for the realtime transactions into the database, and then use another process to sync the data into the real database cluster through network located off the controller node.

This should be similar to Oracle Coherence, or VMware VFabric SQLFire.
