Which is better: Redis or Python dict?

Question

CMS

To create an anonymous chat, I need to choose how to store messages between users. In fact, they will have to be stored for a maximum of 2 seconds, so the idea arose to store them simply in a standard Python dictionary. Tell me, is this a rational decision?

Answer 1

Radish is better. If later you want to scale the chat, you still have to organize communication between several processes.

Answer 2

Yes Yes. I, too, as I wrote this post, immediately realized that the problems begin with an increase in cars, but I'm just learning from this project. I’ll connect to this Redis later, I just wanted to know about performance.
