Returns list with join between tables done or returns raw table and use id field (parent) to do another query? e.g:

[1]

or

[2]

The example here isn't quite correct - in [2] you have a posts field which should be on the User type rather than the Query type.

As your schema scales, fetching all possible data that a user might have will become problematic. For that reason, you generally only want to resolve fields as needed.

Note that resolving users and then each user's posts individually can be problematic as well! This is a commonly encountered problem (named N+1, since you have your first query followed by N queries for posts where N is the number of users you got in the first query). I recommend looking into DataLoader and searching for information on "GraphQL N+1" if you're not already familiar with the topic.
