Good evening,

I have read multiple keyspaces are bad before in a few discussions, but to what extent?

We have some reasonably powerful machines and looking to host an additional (currently we have 1) 2 keyspaces within our cassandra cluster (of 3 nodes, using RF3).

At what point does adding extra keyspaces start becoming an issue? Is there anything special we should be considering or watching out for as we implement this?

I could not imagine that all cassandra users out there are running one massive keyspace, and at the same time can not imaging that all cassandra users have multiple clusters just to host different keyspaces.
