Easy one, to remember arithmetic progression, but if you don't want to bruteforce will work as well

Distributed systems, Tanenbaum.

Pretty similar to consistent hashing, but without a coordinator

Something that is called chord, and it has very interesting way of finding the right node (that has your key)

You have pointers to adjacent nodes (neighbours) + finger table, that is very unclear, but in the nutshell it has exponential “pointers” where the data is. You can chatgpt it.

I am wondering is it much worse than consistent/rendezvous hashing or not. Cause rendezvous does not beed coordinator in theory, as well as consistent

OMG, absolutely love it. This amazing feeling to implement something close to real world.
Not sure how come this is medium, typically, the concurrency knowledge is something that is getting checked in "bank" related algo/oop questions, but in leetcode it is not.

By the way, do you know why it won't work in concurrent world, e.g. 2 transfers at the same time {acc1 => acc2} and {acc1 => acc3)?

How would you handle it? Let's now even abstract it from database, let's say this is only in memory

Pls support with like❤️

Gg to my screen I guess

What I'm busy at midnight?

Proving that no fucking real time system design should have pubsub/kafka approach. Applies to
- messenger
- presence service
- realtime video comments

Just don't do it. I'm so fucking pissed that every second resource on internet suggests this, WTF

I'm prepping for the next system design video/article like that one.

You are my audience, community and people that are supporting me. You gotta be choosing the next one

Did you see this new feature? As I understood now you can invite the friends to code with you
