> Currently (in the latest release 5.11) the MQTT name-space as it's given in the incoming message is stored in the DB.  One optimization I had to make on unsubscribe was to ensure the namespaces lined up with JMS to eliminate a dip into the database for each subscription.. For me to do this, the 'destinations' Map names needed to correlate with the JMS name.. 
> I moved the name conversion to the top layer so as to align these two.. 
> I also had to add a escape feature such that an MQTT Name space could use a '.' in the namespace without major JMS confusion..
