These projects look really solid - they are drop-in replacements for Redis and should offer the most closely matched performance without the need to keep everything in RAM:
Has anyone tried?
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.
