create 2 keyspace, one for production and one for test:
CREATE KEYSPACE atlanteus WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 };
create test keyspace:
CREATE KEYSPACE test WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 };
check if keyspaces were correctly created using DESCRIBE keyspaces;
