Can You Set Different RF Values And Server Counts For The Read Replica Cluster?
September 8, 2023
Read replicas asynchronously replicate data from your primary cluster to a remote region in order to serve low latency reads to users in those areas. Read replicas are observer nodes that do not participate in writes, but get a timeline-consistent copy of the data through asynchronous replication from the primary cluster. They do not guarantee strong consistency and ACID compliance. As such, stale reads are possible with an upper bound on the amount of staleness.

Your primary cluster along with any read replicas make up what we call a Universe in YugabyteDB. Read replicas can have any number of servers, since their server count and replication factor (RF) is completely separate from your primary cluster. For example, if you have your primary cluster in the US, you can extend to a single region in the EU with a single read replica, or you can have multiple read replica nodes in different regions. Since read replicas have their own replication factor, if you want high availability for that replica you would want to have a higher node count and replication factor greater than 1.
