What is the flow of the request in the server?

[special-character]

I am working on speeding up some of my endpoints and am tracing them with Sentry (express handlers). It appears that my resolvers are all fast (<50ms) but it is taking up to a few seconds for the server to "finish" after the resolver is complete.

I took a look at the server source code and see that we pass the request to express when httpServer.on('request') but we also have an Apollo server.

Is there a place that we specifically do something after the resolver is done somewhere? I took out my other middleware functions to limit the complexity but I wasn't able to find out what was happening with the request after it returned from my resolver.

Any thoughts/ideas would be appreciated, thanks!

I think this is because we are requesting way more than we should have in our projects fragment. I am not exactly sure where we resolve the exact fields of the response but it definitely happens outside of the inner resolver (which I had forgotten).

I am going to find out how that happens and see if I can measure it accurately with our tracing with Sentry.
