Join Back Cluster REST Service

Use Join Back Cluster REST Service to rejoin an isolated master server, which is configured in read-write mode, to a Multi-Master cluster. If you detect conflicts when rejoining the master server, first resolve the conflicts, and then run the REST service again to rejoin the master server to the cluster. For more information, see Conflict resolution REST Services.
