Subject Re: Creating key spaces on the fly

Rather than creating a new keyspace consider using the domain as part of a key. 

Generally an application has a single keyspace and a few column families (enough to response
to the queries you expect).

Think about using the domain as the full or partial key, and then creating column families
for each group/type of information you want to read for a single query.
