Custom directive support for federation

Does TYK support custom directive for federation?
e.g.:

Hey @midnight,

what kind of support do you mean?

Directives are notations for server-side code. If, for example, you have a directive “precision” which you can attach to Floats, then it would mean, that the resolver should execute the “precision implementation” on the server.
But for us as Tyk we don’t care about the implementation, we just pass the result back to client. So as long as your backend is able to understand the custom directive, it should work with Tyk without any problems.
