Sending protobuf msg with checksum using CodeedOutputStrem over gRPC

[Yariv Hashai]

Hello, 

I would like to add a checksum to my protobuf msg, as i understood its is possible by using CodeedOutputStrem and write the msg bytes and append a fix sized checksum 

While creating this binary stream, i would like to send it to another endpoint via gRPC

I was thinking about creating another protobuf msg and rpc which will be something like that:

message confWithChecksum {

string bytes = 1;  // this bytes will hold the conf + checksum appnded 

}

The only issue that i have to desirialze the msg twice  - for the the confWithChecksum msg and once for the actuatl conf msg after triming the checksum bytes.

Is there another elegant way of doing it? is there a way to use the grpc and just streaming bytes?

You can send the checksum as a Metadata header.

Hi Yariv, I am not sure what library you are referring to in "ver 2.6". If it's about protobuf 2.6.x, then metadata is a grpc concept, which is independent of the protobuf version being used.

Nice! thanks for that, is that supported also in ver 2.6?
