Benchmark various GraphQL resolving variants

Benchmark various GraphQL resolving variants

There exists confusion about how a GraphQL execution engine like graphql-js does its work. The engine will invoke a resolve function for every [scalar] field in a request.

  • defaultFieldResolver: By default graphql-js will invoke its own defaultFieldResolver resolve function when no explicit resolver was specified when generating the executable schema. This resolver needs to do some reflection on the request in order to determine what data to return.
  • explicitDefaultFieldResolver: We can also use graphql-js's defaultFieldResolver explicitly, which will skip a check for whether or not a field resolver function was specified when generating the executable schema.
  • customFieldResolver: We can also specify our own field resolver function that does not need to perform any reflection, as we know what type to return.
  • customAsyncFieldResolver: Custom field resolvers can also be async. This doesn't make their own execution time much worse, but scheduli

In our application, we have a need to wrap Apollo Client, amongst other reasons we do this to pass default link context to operations. This works well for operations originating from the top-level APIs, but it doesn't for the subscribeToMore function that gets created by useQuery.

We could augment useQuery further and also wrap each subscribeToMore function object that's created, but it struck us that the relationship between the useQuery invocation and the created subscribeToMore function might actually imply that it should inherit the link context of the useQuery invocation. Below you can find a naive patch that does this.

Rewrite GraphQL Live Query to subscription.
/**
* This is a Live Query polyfill, as graphql-js does not strictly have support for that. Instead, we leave it up to the
* client to recognize a Live Query is requested with the `@live` directive on a `query` operation and here we
* transform it into a `live` subscription instead.
*
* Consider a schema like the following:
*
* ```graphql
type Badge {
id: ID!
scalar Date
type Query {
badge: Badge!
}
type Badge {
key: BadgeKey!
text: String!
history: BadgeHistoryConnection!
