So far, through our journey across using Cassandra, we have been working with a single instance to create tables and test all the cool features provided by Cassandra. We haven't taken advantage of the distributed nature of Cassandra. With a single-node cluster, most operations don't require any sort of tweaking or performance tuning. Even the configuration operations can be left as default for the most part. But with a multi-node cluster, quite a few changes are required in order to get a balance between throughput and availability as well as getting gossip and other internal Cassandra operations to work properly. In this section, we will set up a 3-node cluster.

You can set up a single-node cluster on your personal laptop...
