On the surface, setting the replication factor seems to be a fundamentally straightforward idea. You configure Cassandra with the number of replicas you want to maintain (during keyspace creation), and the system dutifully performs the replication for you, thus protecting you when something goes wrong. So by defining a replication factor of three, you will end up with a total of three copies of the data. There are a number of variables in this equation, and we'll cover many of these in detail in this chapter. Let's start with the basic mechanics of setting the replication factor.
