    Description

      Currently Couchbase Server requires a minimum of 3 Data Service Nodes in order to have automatic failover of a failed node as a quorum is required to prevent split-brain issues

      With the move to Chronicle, we should investigate if having a cluster of 3 or more nodes is enough to establish quorum where only 2 of the nodes in the cluster are running the Data Service.    So for example a 4 node cluster where  2 nodes running the Data Service and 2 nodes are running Query+Index.
