> This is to keep track on the statistics of the latency for the requests done on Cassandra layer through Cassandra Resource Provider. Here we use Apache Benchmark.
> We have a test profile java component in the cassandra module to add bulk test data to cassandra.

> /content/cassandra/B/0 to /content/cassandra/B/9999
> /content/cassandra/C/0 to /content/cassandra/C/99999
> /content/cassandra/D/0 to /content/cassandra/D/999999
> And then this JIRA will keep track of reports on the http request time to retrieve 1 node from each following data collection.
