Instance Attribute Details

#name ⇒ ::String

Returns The name of a locality load-balancing policy. Valid values include ROUND_ROBIN and, for Java clients, LEAST_REQUEST. For information about these values, see the description of localityLbPolicy.

Do not specify the same policy more than once for a backend. If you do, the configuration is rejected. Check the Name enum for the list of possible values.
