Description

I have the following query:

```graphql
{
user(id: $id) {
username
comments(last: 10) { # How can I handle pagination here?
id
body
author {
username
}
replies(last: 3) { # How can I handle pagination here?
id
body
}
}
}
}
```

How can I handle pagination in those cases? Should I use DataLoader?

Until now, everything that I found on the web suggests using the `splice` array method, but if I use it, my server will run out of memory, as I should paginate the data on the SQL query, am I right?

So how I am able to query my database with such GraphQL query? Do you handle those cases in any of your projects?

I am really struggling with that. It is even possible to use DataLoader in this case? And if I not use it, I my server will suffer a lot with the N+1 problem...
