Subject Re: cassandra-stress with clustering columns?
Date Sun, 17 Aug 2014 20:08:45 GMT
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?
