Creating a demo keyspace for tutorials

Step-by-step instructions to create a keyspace for tutorials found in this section.

Procedure

Get a list of datacenter names (DC) in the cluster.

dsetool status

The header line contains the datacenter name (

DC:
                            datacenter_name) and the type of
                    workload.

DC: Cassandra       Workload: Cassandra       Graph: no
======================================================
...

DC: Solr            Workload: Search          Graph: no
======================================================
...

Start a cqlsh session:
```
cqlsh
```
Tip: To connect cqlsh to a remote node use the host switch with the hostname or IP address.
Create a demo keyspace with a replication factor of 1 in each datacenter.
In multi-datacenter environments use NetworkTopologyStrategy and set the replication factor for each datacenter to at least one.
```
CREATE KEYSPACE demo 
WITH replication = {
    'class': 'NetworkTopologyStrategy', 
    'Cassandra': '1', 
    'Solr': '1'};
```
Note: Datacenter names are case-sensitive. Exit cqlsh and ensure that the name exactly matches the DC name from the dsetool status output.
