public enum HostDistance extends Enum<HostDistance>
distancemethod). The distance assigned to an host influences how many connections the driver maintains towards this host. If for a given host the assigned
REMOTE, some connections will be maintained by the driver to this host. More active connections will be kept to
LOCALhost than to a
REMOTEone (and thus well behaving
LoadBalancingPolicyshould assign a
REMOTEdistance only to hosts that are the less often queried).
However, if a host is assigned the distance
IGNORED, no connection
to that host will maintained active. In other words,
be assigned to hosts that should not be used by this driver (because they
are in a remote data center for instance).
