What is the correct way to design a Mongo base?

Question

MongoDB

Good evening!
There was a problem. I just can not unlearn from the relational approach to building a database. Tell me how best to design a many-to-many relationship in mongodb, taking into account the heavy load on it.
Task: there is an entity "user", conditionally, with _id and name. There is a news model, which has a title, text, photo. News is sent to users. It is necessary to associate news for each user in order not to duplicate the news for new users when resending.

Answer 1

If there are many-to-many relationships, then it is better to use tools suitable for this, for example, relational DBMS.
