Serialized data access for C++ async server

[Aniruddha Bohra]

Hi,

 I have a C++ based gRPC based bidirectional async streaming service. For failure recovery, we would like to store the incoming data to stable storage at the server. While implementing the service is easier with the already deserialized message, taking such a snapshot requires serializing the message again before writing to disk. 

 Is there a way to get the bytestream that was then parsed by the protobuf parser to generate the message received by the callback ? 

Thanks

AFAIK there is no way for that. You may have a way by using SerializationTraits that handles (de)serialization but it's not recommended since it's not designed for that purpose.
