Your question is too abstract to be answered.

What ORM are you using ? Mongoid ? How do you use Mongo ? Models
structure? Their relations ?

Anyway, I had same problem; at some point I wanted to switch back from
mongo to mysql because as you say ‘some concepts are not working’.
However, given amount of work this implied I rethought the problem and
found that core issue was in my model structure.

Here I from what I realized from my own experience with mongo:
We are used to think relational, but Mongo is not relational, and
because of this models for mongo and for rdbm will be different. In my
example, I almost gave up Mongo because of too many relationships, where
Mongo is poor.

To solve relationship (has_many/embeds_meny) issue I removed a few
models and made then dynamic fields, which is piece of cake in Mongo and
not possible with MySQl !!!

Think twice.
