The Replication Factor is a strategy that is used in designing Cassandra to handle Big Data efficiently and preserving the data is a priority, and therefore, it stores data on different nodes. As any node could go down at an instant, we can use the data from a different node to get the work done.

So, a Replication Factor of 1 means, there is only a single copy of the data, and if RF is 2, it means there are 2 copies of the data.
