MongoDB

From their Website

MongoDB is a general purpose, document-based, distributed database built for modern application developers and for the cloud era.

MongoDB free monitoring.

To disable the message about free monitoring you can run db.disableFreeMonitoring().

Security

MongoDB 6+ eggs enable access control by default in the mongod.conf file, meaning that even if people will be able to connect to your database as guests, they will not be able to perform any operation, apart from nonhazardous commands

Disabling authentication

If you know what you are doing and want to explicitly disable access control, you can edit the following lines to your mongod.conf file:

security:
  authorization: "disabled"

Minimum RAM warning

MongoDB requires approximately 1GB of RAM per 100,000 assets. If the system has to start swapping memory to disk, this will have a severely negative impact on performance, and should be avoided.
