Ask HN: I don't get GraphQL. How do you solve the N+1 issue without preloading?

A neighborhood has many homes. Each home is owned by a person.

Say I have this graphql query:

    {
        neighborhoods {
            homes {
                owner {
                    name
                }
            }
        }
    }

I can preload the owners, and that'll make the data request be a single SQL query. Fine.

But what if I don't request the owner in the graphql query, the data will still be preloaded.

I'm not sure if this is a solved issue, or just a painpoint one must swallow when working with graphql.

Using Absinthe, DataLoader and Elixir by the way.
