FWIW I tried just removing indices from my table and rerunning my write load test and I got about 2x the performance. I'm still interested, however, in seeing whether I can replicate my table layout in cassandra-stress, just so that I can normalize my results.
Should the presence of clustering columns make a big difference in write performance?
