Great explanation!
For the single partition read, it makes sense to read data from only one
replica.
Thank you so much Ben!

Each individual read (where a read is a single row or single partition) will
read from one node (ignoring read repairs) as each partition
distributed across all the nodes in your cluster).

Hi there,
I have a question about the replica and replication factor.
For example, I have a cluster of 6 nodes in the same data center.
Replication factor RF is set to 3 and the consistency level is default 1.
