Aaaaarrrgggghhh! I feel like I post this same comment whenever the discussion is about GraphQL.
I love GraphQL. What I hate about GraphQL is that it has "QL" in the name, so it confuses people into thinking it's somehow comparable to SQL. The question "How is GraphQL for aggregate queries?" doesn't even make sense.
GraphQL is simply another format for APIs. E.g. you could do APIs with SOAP, using REST, or with GraphQL.
