OperationInfo

A message representing the message types used by a long-running operation.

Example:

rpc Export(ExportRequest) returns (google.longrunning.Operation) {
  option (google.longrunning.operation_info) = {
    responseType: "ExportResponse"
    metadataType: "ExportMetadata"
  };
}
JSON representation 
{
  "responseType": string,
  "metadataType": string
}
Fields
responseType

string

Required. The message name of the primary return type for this long-running operation. This type will be used to deserialize the LRO's response.

If the response is in a different package from the rpc, a fully-qualified message name must be used (e.g. google.protobuf.Struct).

Note: Altering this value constitutes a breaking change.
metadataType

string

Required. The message name of the metadata type for this long-running operation.

If the response is in a different package from the rpc, a fully-qualified message name must be used (e.g. google.protobuf.Struct).

Note: Altering this value constitutes a breaking change.
