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

IGNORED should be assigned to hosts that should not be
used by this driver (because they are in a remote data center for instance).
