      • allowConnectingTo

        public abstract boolean allowConnectingTo​(HostStatus status)
      • getTargetServerType

        public static HostRequirement getTargetServerType​(java.lang.String targetServerType)

        The postgreSQL project has decided not to use the term slave to refer to alternate servers. secondary or standby is preferred. We have arbitrarily chosen secondary. As of Jan 2018 in order not to break existint code we are going to accept both slave or secondary for names of alternate servers.

        The current policy is to keep accepting this silently but not document slave, or slave preferSlave

        Parameters:
        targetServerType - the value of targetServerType connection property
        Returns:
        HostRequirement
