Introduction to CLI

This section gets you acquainted with another tool that is used for interaction with Cassandra processes—the CLI shell.

The following steps are used for interacting with Cassandra using the CLI shell:

1. The following is the command to connect to the Cassandra CLI:

   Cd Cassandra-installation-dir/bin
   cassandra-cli -host localhost -port 9160
   

2. Create a keyspace:

   [default@unknown] CREATE KEYSPACE myKeySpace
   with placement_strategy = 'SimpleStrategy'
   and strategy_options = {replication_factor:1};
   

3. Verify the creation of the keyspace using the following command:

   [default@unknown] SHOW KEYSPACES;
     Durable Writes: true
       Options: [replication_factor:3]
     Column Families:
       ColumnFamily: MyEntries
         Key Validation Class:  org.apache.cassandra.db.marshal.UTF8Type
         Default column value validator:  org.apache.cassandra.db.marshal.UTF8Type
         Columns sorted by:  org.apache.cassandra.db.marshal.ReversedType (org.apache.cassandra.db.marshal.TimeUUIDType)
