I realize it is not a good idea to create more than one (or a few) keyspaces. But in our current design we are required to create 3400+ keyspaces, each with 12 column families (one of them is a super column). I have created one large cli file with statements to create the keyspaces, and the column families within the keyspaces, and am loading it using cassandra-cli. The rate of keyspaces creation is about 9 per minute when the loading first starts. After a few hours, the rate of keyspaces creation comes down to about 3 per minute. I have tried lowering the compaction throughput to 0, but the rate of keyspaces creation is still sluggish. What can I do to increase the rate of keyspaces creation?
