Couchbase Groups and replicas

Can someone explain how a cluster would act if it was created with 3 groups and 1 replica? Would the data from one group replicate to only one other group and that other group would replicate to the initial group. Trying to see if it’s meshed if couchbase is smart enough about this.

reason for the question is I have 2 replicas with 3 groups and the resource hit is to much. So was thinking about removing 1 of the replica’s, but again wanted to make sure couchbase was smart enough on how to create that one replica between groups.


To give an accurate answer we will need some extra information about your cluster. Can you provide us with the Couchbase Server version, total number of nodes in each server group, and the Couchbase SDK version you might be using?
