Data is replicated/copied on my 2nd node even with a replication factor of 1 for the key-space

Author: Naveen

I have a Cassandra cluster of 3 nodes and I create a keyspace 'abcd' using SimpleStrategy and ReplicationFactor 1. Since I have chosen RF as 1, I assume that any writes to my node-1 should not be replicated across the other 2 nodes.

But when I inserted a record into keyspace/table, I saw this new row is getting inserted in to all nodes in my cluster.

My question is since I have chosen RF as 1 for this keyspace, I would have expected only one node (i.e. node-1) in this cluster should have owned this data, not the rest of the nodes.

Pease correct me if my understanding is wrong.
