Hi, while you're welcome to post here, this is not a general forum for Node. It's the community forum for NodeBB, a Node.js based forum software.
You'll probably have better luck with your question on StackOverflow or Reddit.
Every now and then when I browse the forum I see that most people are using MongoDB instead of Redis.
However, as Redis is faster (at least from what I have heard) I wonder why the majority is going for Mongo?
Is there any benefit?
I am well aware that Redis needs RAM, however as of now prices for RAM are hilariously low compared to a year or two ago.
