Default Recator for Streaming Request

[Brent Edwards]

For a unary server request you can use a default reactor.
e.g.
grpc::ServerUnaryReactor* reactor = context->DefaultReactor();

If there such an "Default" reactor for a server streaming request

e.g. 

grpc::ServerWriteReactor<GetTracksResponse>* reactor = context->DefaultWriteReactor<GetTracksResponse>()

[Brent Edwards]

This is for a service with callback processing enabled i.e. service derived from CallbackService

Could you elaborate your suggestion? I cannot see why it's useful. Usually streaming request reactor needs some state to handle writing a series of messages to the peer.
