Why REDIS?

[MOHITRAJANI]

Hey Community, I have a very generic question for the planners and all contributors of such a great library. That question is, why is BullMQ backed with REDIS In-Memory Database?
It could have been any other database also right? Probably MySQL or maybe even MongoDb?
I ask this question because I am currently implementing my Thesis and this question was raised to me when I had to choose a Database solution for my architecture.

If someone could list down a few points that lead to this decision I would be obliged to them.

Thanks in advance.
