RethinkDBとそのサブクエリ機能についてもっと知りたいと思っています。ReThinkDBで次のことが可能かどうか疑問に思いました。
// example of "post" document:
{ id: .., allow: [], disallow: [some_label_id, other_label_id], ... }
// example of "label" document:
{ id: .., user_id: .., name: 'my-label' }
var MY_USER_ID = "1b4-4c6-7d9"
// Query in psuedo-code:
IN database test
IN table posts
FILTER out any "posts" where the "disallow" array
contains a value found in this sub-query:
IN table labels
FILTER id .eq disallow[index] AND user_id .eq MY_USER_ID
