Getting started with CQL

With some quick definitions of CQL data modeling and cqlsh completed, now we'll take a look at CQL. The basic commands for creating data structures (keyspaces, tables, and so on) will be covered right away, with command complexity increasing as we build more useful structures.

Creating a keyspace

Keyspaces are analogous to the logical databases of the relational world. A keyspace contains tables, which are usually related to each other by application, use case, or development team. When defining a keyspace, you also have the ability to control its replication behavior, specifying pairs of data center names and a numeric Replication Factor (RF).
