> As I mentioned over on HBASE-9940, I'd like to have randomRead operate only on a sample
of the total dataset. It would also be useful to collect latency measurements from individual
responses. Throughput times are aggregated according to the amount of user data processed
and the result is reported as well. This is a patch I've been using for some performance tests
I've run -- maybe it'll be useful to someone else.
