These records will allow the driver to determine the exact Couchbase servers that provide the appropriate CouchbaseService. You must also set the DNSServer property so that the driver is able to fetch these service records.
Note that enabling Cloud mode will override these connection properties with the values discovered by contacting the cluster:
