MongoDB replacement?

Question

MongoDB

Due to the current circumstances, we have been banned from using mongodb. Are there any analogues?

Answer 1

A great reason to get rid of this ridiculous misunderstanding and start using a normal database.
If we are talking about a database, then the choice is huge: mysql, postgres, sqlite, sql-server, oracle
You can choose a DBMS to your liking, plan the database structure instead of the orgy with getters that is used in Monge and start using it.
If we are talking about in-memory key-value storage, then there is a smaller choice, but there is also redis or the now forgotten memcache.

Answer 2

Selection of the base is the competence of the architect. The architect selects it as part of the internal architecture of the application. Chooses the one that best covers exactly the needs and shortcomings of which will not affect the operation of the application.
How can we advise you something here without, at least, a case or application purpose?
