To demonstrate partitioning, let’s create a simple table and insert some rows to see how they are distributed around the cluster.
Creating container keyspace for the table
A keyspace holds a related set of tables and defines the number of nodes that store copies of each row.
Creating a keyspace titled testkeyspace with replication factor 2
A replication_factor of 2 means each row of each table in this keyspace will be stored twice in the cluster—on two different nodes.
The USE <KEYSPACE> command selects the keyspace for all subsequent queries. Notice that cqlsh:>testkeyspace displaying testkeyspace has been selected for the ...
