public enum HostDistance extends Enum<HostDistance>
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
LOCAL host than to a
REMOTE one (and thus well behaving
LoadBalancingPolicy should assign a
REMOTE distance only to hosts that are the less
However, if a host is assigned the distance
IGNORED, no connection to that host will
maintained active. In other words,
IGNORED should be assigned to hosts that should not be
used by this driver (because they are in a remote data center for instance).
