RequestMirrorPolicy(mapping=None, *, ignore_unknown_fields=False, **kwargs)

A policy that specifies how requests intended for the route's backends are shadowed to a separate mirrored backend service. The load balancer doesn't wait for responses from the shadow service. Before sending traffic to the shadow service, the host or authority header is suffixed with -shadow.
