I am new to Couchbase. We are planning to use 3 server groups one for each zone in our GKE cloud. From the documentation, (https://docs.couchbase.com/server/6.0/learn/clusters-and-availability/groups.html#group-failover-and-service-availability), it’s clear the case of 2 groups (each bucket has a replica in the other group). What happens in case of 3 groups? will each bucket has 2 replicas (in the other two groups).
I am assuming there should be a way to configure number of replicas to maintain the cluster. Can you please let me know where to configure that if that is the case/or point me to any documentation?
Please do let me know if you have any questions.
