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.
str
The full or partial URL to the BackendService
resource being mirrored to. The backend service
configured for a mirroring policy must reference
backends that are of the same type as the
original backend service matched in the URL map.
Serverless NEG backends are not currently
supported as a mirrored backend service.
This field is a member of oneof_ _backend_service.
mirror_percent
float
The percentage of requests to be mirrored to
backend_service.
This field is a member of oneof_ _mirror_percent.
