The server-assigned name, which is only unique within the same service that originally returns it.

public string Name

Field Value

Remarks

If you use the default HTTP mapping, the name should be a resource name ending with operations/{unique_id}.

Response

The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty.

Remarks

If the original method is standard Get/Create/Update, the response should be the resource. For other methods, the response should have the type XxxResponse,
where Xxx is the original method name. For example, if the original method name is TakeSnapshot(), the inferred response type is TakeSnapshotResponse.
