If the request requires querying across 2 (or more) databases, we need to track how many results were loaded with the prior DB query. So if the query to modb-01 returned 20 results, and the request wants 50, we need to know that we only need the next 30 from the next DB. Now when querying modb-02 and we get 20 results as well, the `page_size` should be 40, not 20. So, how are you accounting for this?
