gRPC with C programs

[raut...@gmail.com]

Hi,

So, I have a rather embarrasing question.

We have a distributed system with a lot of services in C, which use protobuf2.

I want to use gRPC for our Data access Layer (not ready yet), and thus decided to use go lang.

But the rest of the services are C based and since gRPC needs protobuf3(which does not have a C compiler), I am stuck for now.

Suggestions on what approaches I can take, apart from manually write a library layer which converts between proto2 and proto3 before feeding to a gRPC client stub or gRPC server.

Thanks,
