Create a keyspace

CREATE KEYSPACE demo WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 1};

A keyspace (similar to database in relational DB) is a collection of database objects together, such as:

• tables (or column families)
• user-defined types
• user-defined functions
• replication settings
• and more!

The keyspace also controls the replication behavior for all of the data stored in the keyspace.
