How twitch deals with storing so much data in realtime chats, lives…, it looks like there i huge read and write for every second

Answer 1

There is a lot of reads and writes which is not possible for single server to handle, but combination of distributed servers across the world (more than 500, but couldn’t find exact number) will do the job.
So every server will take a load from closest clients.
Then you have a caching, which stores frequently accessed or lately accessed data for fast deliver. Imagine that being stored in RAM instead of the Hard drive.
