I really appreciate this, thank you

For the folk's who thinks this is overwhelming stick till the end and watch it saw alot of comments from such guys i am a newbie too still i understood few portion of it for sure combing back again after gaining more knowledge.Great content thanx kirat sir and arpit

[@anupamdeo904]

That's what everybody should be learning - First Principal Problem Solving, One step at a time and then suddenly you will be breaking the odds.

[@pajeetsingh]

Really don't care. One could just patch up bunch of projects from GitHub and make clones or even make better versions. India's tiktok clone Moj was bootstrapped in just 90 hours. Literally, probably nobody in their dev team start with first principles.

[@pajeetsingh]

Corporations aren't wasting time on that. Programs extend existing programs for a reason.

[@advaitathreya5558]

Timestamps: 4:30 Why Distributed DB reqd? + Monolith vs MicroService + 1st principle for system design patterns -> If single node cannot handle the service, then distribute. Distribution requires data splitting or sharding 07:00 Routing basics -> static routing + storing metadata - 08:00 Framework of opposites : don't wanna store metadata -> use a mathematical function named hash don't wanna use routers -> Either middleware knows databases .. or client knows databases 11:00 - CS design patterns are inspired by real-world basics 13:00 - Consistent Hashing

[@jatintilwani8557]

Love Arpit Sir's way of teaching, the way he simplified "Senior Engineer" concepts to basic principles / algorithms, truly shows his depth of knowledge in computer science topics. Please make more such videos, learnt a lot !!

[@onepotatochips]

Wow, this video is a literal gem, Loved it...harkirat please bring more videos like this

[@alec-dora]

All the success story videos are great but videos like these are the ones I'd pay to watch.

One of the best videos I have watched so far, would love more videos like this

[@PythonicMayankVishwakarma]

It's really nice to see how things actually work behind the fancy words and on such fundamental concepts which everyone knows about, the only difference is taking a step further to dig deep on the implementation. Loved the complete session 🤍🤍

[@vp--]

This is gold!!!! , thanks a lot for uploading this

[@VivekYadav-ds8oz]

These concepts are really not that hard to think of (of course excluding the epoll kernel syscall, you either know about it or don't). It's kinda surprising people can't put that 2 and 2 together. This is why I'll always die on the hill that more people need to care and learn about what's going on under-the-hood. You're so much confident when theorising or building stuff when you know what's _actually_ happening (what/how many connections are made, what syscalls might be happening, what part is too computationally/IO heavy, what are the libraries doing, etc.). It also naturally develops this first-principles thinking. All of this came to me naturally as a consequence of knowing my stuff, I did not get stuck at any of his questions. I'm not special or very smart. Just dive deep.

[@harshsharma2450]

Why did the note sharing stop after 24:00?

[@priyanshrawat442]

This lecture was so insightful !

[@SONU_RAJ518]

Interesting class in System design, Arpit Bhaiya class like why in everythings

[@highlycurious]

47:16 Sir will it not be an overhead if we will check every time if the array if full so that we can start referencing to second array.

[@code-master]

I don't know why this seems a big problem you basically need to rebalance only 1 node and do bisect ordering when adding a new node. Use the shard key as array values, and when a new shard is added, use bisect ordering to figure out new pos and refills. The Shard key should not be monotonically incrementing. I don't have CSE background.

[@gurkaran_singh]

4:55 for god sake, THANK YOU! someone finally said that! -- they think its fancy and scalable but project shuru hua nahi microservice thokna hota hai newbies ko, cuz its cool for them -- its a fucking overhead -- go to market is most important

[@saketramsinghani195]

I respect Arpit as an engineer, but this was not a good session . Maybe people who attended it offline might find it useful. The things seem to be bit rushed. Rather than sparking curiosity this will overwhelm a lot of students. PS:- No hate to him, I think he is a good engineer, but teaching things is different.

[@Abhinav_2060]

Exactly bro.. thank god I found your comment. I felt so overwhelmed so worthless in the first 10 mins. I stopped watching. Will re-watch it maybe after year.

[@priyanshrawat442]

People who found it overwhelming has skill issue lol

[@saketramsinghani195]

@@priyanshrawat442 You can say that. But context matters. The students he is teaching are freshers and I don't think this is how you teach topics. If it would have been for people who have more experience and already know most of the concepts on a high level it would be ok. But still freshers or experienced, this is such a vague style of teaching. Everything seems to be all over the place.

[@adityaghadge2067]

It's normal to feel overwhelmed sometimes; not everyone has the same background or understanding. The key is to keep learning and pushing forward. One day, you'll look back and see how far you've come. Many concepts discussed here are part of CS syllabuses, though they're often not taught in ways that highlight their real-world value. Arpit's approach might feel fast-paced, especially if you're not familiar with some of the topics yet, but that's part of the learning process. It's a great reminder of the importance of these concepts.

what are the prerequisits of this video ? i was not able to understand majority of it 🙃

this is system design thing. Just knowing this and some famous algorithm and system design principle would be the prerequisite. (this is my opinion, i dont know how much is absolutely correct)

what I don't like about these sessions is that it is still not very hands on! real engineering is I write actual code for say a basic server in say C or Rust and show some tool like iptraf to see the sockets, use tcpdump/wireshark to capture packets sent & received, display threads etc on a unix system! can get more deep also! Write unit tests!!! He talks about epoll and io_uring but show some code in action for event loop! go deep and not talk 10 things, that real engineering for an hour tbh.

[@hemanthaugust7217]

Why they hell are oyu sharing all this with folks? this is supposed to be learnt on the job. You guys have already screwed up the design interviews by sharing designs of various systems, even when they have not designed any system. Now, they know all these things in bits and pieces and behave as if they have built it, in the interview. It only makes our lives difficult as interviewers. We have learnt all the concepts you mentioned on the job and implemented them in low-latency systems in C.
