[RFC] compile createSourceEventStream

[Dschoordsch]

Creating a source event stream from the compiled query is about 1.5 to 2 times faster. The use case for createSourceEventStream is running the event stream and resolvers in different processes. That means compiling the resolvers is not necessary and just costs performance, thus a separate function is exposed for just this use case.
It does not actually compile anything, but that's an implementation detail und thus compileCreateSourceEventStream name was chosen.

This needs some polishing and tests, but I would like to know if you're interested in this at all?

@markrzen could you take a look and let me know if this is something you would be willing to accept? If yes, I will polish it up.

Hey @Dschoordsch, I am not a maintainer of the library. You will want to ping the good folks on this list:

I wont have time before the weekend to check it.

[Dschoordsch]

@ruiaraujo did you have chance to take a look whether or not a compileCreateSourceEvent function would be something you would accept?

[Dschoordsch]

@boopathi could you take a look if that's something which you would be interested in?

@Dschoordsch We would like to learn if there are more needs for this in the GraphQL JIT user community

Subscriptions are essential for our service, so at least we'd be interested in trying this out. I've checked createSourceEventStream in graphql before, and frankly speaking I'm not fully aware of how it works these days. Probably some kind of "for dummies" explanation would be great. :)
