MongoDB vs MySQL. For what tasks, which database is better suited?

Question

MySQL

Asking the question "which database is faster", you will get the answer: "depends on the task." It is logical, but no one ever talks about the scope of a particular database. I would like to ask those who understand this topic. For what tasks, which database is best suited?

Answer 1

imagine a muscle without joins, but with the ability to break 1NF. receive a MONGO.
it will not be faster in direct hands, and never has been.
and the fashion for it has long passed, and thank God. a lot of people liked to show off, monga. it’s just that for many, the rsubd with the lowest entry threshold turned out to be too complicated, hence the exaggerated popularity at one time.

Well, as it were in nature - it depends on the task!
And which tasks for which database - depends on the task :)
