Adding metadata to an RPC

[Guy Pardon]

Hi,

Being new to protocol buffers and gRPC, I am looking for a good way to add metadata "annotations" to the contract description.

In particular, we are adding transaction context propagation across gRPC calls. We would like to mark some RPCs (or services) as "transactional" - meaning that they expect / support a transaction context header in the incoming request.

What is the recommended way of doing this? I did not seem to find this in the documentation.

Thanks,

Guy

"custom options" exist, but frankly they don't do much unless you have custom code generation that is going to emit something useful from them, and that "something" itself does something useful at runtime - which may itself be tricky between runtimes/platforms.

Does "add a comment" suffice?

Makes sense, thanks.

Alternatively, there seem to be Java options that we could define? (since we're doing Java)
