Instance Attribute Details

#name ⇒ ::String

Returns The name of a locality load balancer policy to be used. The value should be one of the predefined ones as supported by localityLbPolicy, although at the moment only ROUND_ROBIN is supported. This field should only be populated when the customPolicy field is not used. Note that specifying the same policy more than once for a backend is not a valid configuration and will be rejected. Check the Name enum for the list of possible values.
