Setup
-----
Run `ant` from the Cassandra source directory, then cassandra-stress can be invoked from tools/bin/cassandra-stress.
cassandra-stress supports benchmarking any Cassandra cluster of version 2.0+.
Usage & Examples
----------------
See: https://cassandra.apache.org/doc/latest/tools/cassandra_stress.html
cassandra-stress write n=2 -mode user=cassandra password=cassandra
cassandra-stress read n=2 -mode user=cassandra password=cassandra
