Hi,

thanks for all the answers, I will look deeper into ocaml-protoc.

As a kind of follow-up question. Do you add some kind of unique identi= fier to every message to allow resending the message in case some service g= oes down?

Thanks again for the help here I highly appreciate it,

Betreff:=C2=A0Re: [Caml-list] Protobuf for ocaml
The difference between ppx_deriving_protobuf and ocaml-protoc is that = the former generates a protobuf schema from an OCaml type while the later g= enerates the OCaml type from a protobuf schema. They are both using the sam= e runtime library for the binary encoding.

Although I have written ocaml-protoc as a personal project, it has bee= n used successfully in a professional context to interface with apache meso= s.
