Thanks for all your replies. I was thinking to modify YCSB to support lightweight transactions in order to measure the overhead introduced. Since YCSB extends thrift api this is the only way to do it. I am not quite sure how to use CAS but I am now looking at it. If there is an easier way to measure the performance of my cluster under different kind of operations please let me know.
