To elaborate on what Robert said, I think with most things technology related, the answer with these sorts of questions (i.e. "ideal settings") is usually "it depends." Remember that technology is a tool that we use to accomplish something we want. It's just a mechanism that we as humans use to

hi; we are deploying a new cluster with 2 datacenters, 48 nodes in each DC. For the system_auth keyspace, what should be the ideal replication_factor set? We tried setting the replication factor equal to the number of nodes in a datacenter, and the repair for the system_auth keyspace took
