Is it possible to limit the depth of the request when receiving a document?
I noticed a large performance drawdown when a table of not many relationships is obtained. Is it possible, like sql, to simply get an id from related objects.
How to speed up query performance?
TL;DR
There is a problem with the performance of database queries. One suggestion is to not use relationships and store the ID as a string instead.
