---------------------------------------------------------------------
First round of report in brief: P.S This results based on very first time retrieval of these nodes (with in a single server startup).
1. http://localhost:8080/content/cassandra/A/100.json - Time per request: 65.449 [ms]
2. http://localhost:8080/content/cassandra/B/100.json - Time per request: 73.022 [ms]
3. http://localhost:8080/content/cassandra/C/100.json - Time per request: 61.696 [ms]
4. http://localhost:8080/content/cassandra/D/100.json - Time per request: 71.855 [ms]
Same round of test results, but each node retrieval done in a fresh server start.
1. http://localhost:8080/content/cassandra/A/100.json - Time per request: 65.449 [ms]
2. http://localhost:8080/content/cassandra/B/100.json - Time per request: 236.641 [ms]
3. http://localhost:8080/content/cassandra/C/100.json - Time per request: 260.856 [ms]
4. http://localhost:8080/content/cassandra/D/100.json - Time per request: 233.855 [ms]

> 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.
