receiving the byte array for a protobuff in a streaming grpc

[Elhanan Maayan]

hi..

is there a way for a streaming call in grpc to accept it's binary array prior to it being turned into protobuff? 

i'm aware that protobuff itself has this ability, but getting the byte array , turning it into an object and then turning it back to byte array seems redundant. 

the reason is that i'd like to create a "recording file " of the incoming traffic (to be played back later).

You don't have to use the proto generated stubs.   You can make your own serializer / deserializer and persist the data.  You can even delegate to the next serializer and reuse the proto ones, if you want.   (this is for Java)
