I like the idea to use a DB for storing cache data. May be it is a good
idea to store config data in a DB as well, but I an not sure that it is
a good idea to store configuration and cache data in the same DB (IMHO
it is a bad idea).

I am not sure that I understand the SizeThreshold parameter. Is this the
amount of data (MBytes or data sets) that are stored in the cache DB?
What are the consequences if I set this value to 0 or a even higher
value than the default.
