MongoClient::DEFAULT_PORT
27017: Port to connect to if no port is given.
MongoClient::RP_PRIMARY
"primary": Read preference for the primary replica set member.
MongoClient::RP_PRIMARY_PREFERRED
"primaryPreferred": Read preference for preferring the primary replica set member.
MongoClient::RP_SECONDARY
"secondary": Read preference for a secondary replica set member.
MongoClient::RP_SECONDARY_PREFERRED
"secondaryPreferred": Read preference for preferring a secondary replica set member.
MongoClient::RP_NEAREST

connected: This property will be set to TRUE if we have a open connection the database based on the ReadPreference and tagsets (for ReplicaSet connections), FALSE otherwise. This property does not take authentication into account.
