But in the case of GraphQL, like I may get an incomplete list, or I may get a complete list that will have some fields with missing data, or some combination of both, going down deep depending on the structure of the query. I don't see a clear way to request the missing data without duplicating part of what I already have, and I don't see a clear way to combine the results.

But I may be missing something about GraphQL or something about the tools that makes this simple.

For example something like this:

    {
      users(first: 10000, after: "cursor123") {
        edges {
            cursor
            node {
                id
                name
                friends(first: 10000, after: "cursor235") {
                    edges {
                        cursor
                        node {
                            id
                            name
                        }
                    }
                }
            }
        }
     }
    }
