It definitely isn't. And, once again, dataloaders are just the first step.

Even with a "general way" your REST endpoint knows what actual request or a type of request it's solving. So, instead of doing several requests to the database where each request is essentially "SELECT *", you'll be doing queries optimised for the specific request type.

And there are many-many other things. Like caching. For which Apollo has to unpack and look into every single request and response, for example (and libraries in other languages don't solve at all).
