L17: Consistency Models in Distributed Systems

preview_player
Показать описание
What does it mean when someone talks about "consistency models", or "relaxed consistency"? Here we review what it means to keep data consistent in a distributed system, covering strict consistency, sequential consistency, FIFO consistency (a.k.a. PRAM consistency), release consistency, and eventual consistency.

Another great example of eventual consistency is everyone typing "first" in youtube comment section and later realised that there are at-least 2 dozen such comments :P
Thanks for the great content !!

Watched the other videos years ago and these are still the best videos on distributed systems on all of youtube [even better than the lectures I was exposed to in my undergrad in computer science] hope you continue to make more of these videos.

Great video! Loved each of the explanations. Am I correct in saying that Strict consistency = Strong consistency and FIFO consistency = weak consistency?

Wrt. Eventual consistency... The issue becomes: What's the "latest".
It might not be what the clients expected... Even though it's consistent

Hi, your videos are amazing and I watched your videos instead of attending the boring lectures at my university. 🤣
If possible, you could make a video about Raft since it's very popular in the industry right now. I'll definitely watch it if you post it!
