Just an opinion here as we are having to do this ourselves loading tons of researchers datasets into one clusters. We are going the path of one keyspace as it makes it easier if you ever want to mine the data so you don't have to keep building different clients for another keyspace. We ended up adding our own security layer as well so researchers can expose their datasets to other researchers and once exposed, other researchers can join that data with their existing data.
This of course is just one use case, but if 10 applications use cassandra, you still may find a benefit in having an 11th data mining app look at the data from all 10 apps.

Is any of the models suggested over the other? Thanks. -- Ersin Er
