There is lot of homework done in any of your video. You just not come up with a any generic solution which could be applied, but actually the solutions which are currently being used in the company (be it twitter/Netflix). Kudos man, great work! :)
Thanks @Atul :)
@@TechDummiesNarendraL Thanks for your videos. Just wanted to know how can we be sure this is the technical stack used in the companies? Any checks you made with the developers of those company?
I loved the way you keep the videos informative enough for the experienced to stay glued and simple enough for the beginners to understand. Great work Narendrea. Appreciate the way you are converting PAPERS to these great VIDEOS.
Your work is brilliant. You always include small details like "What is Fanout? Fanout is moving from a single point to different directions.". That level of detail is amazing because you are not taking things for granted (i.e. that everyone knows what a fanout is; I initially always got confused by the concept of fanout actually) it makes it much easier to grasp the material! Thanks!!!
It is almost impractical to cover each and every aspect of all components that make up a system in a single video, unless it is several hours long. However, Naren does a great job in putting the most important information across in a way that is simple and easy to understand. He also makes sure he uses the exact keywords and terms that interested users can later research on for a more holistic view into every design. Thanks a ton!!
When I research the design for a particular product, I watched at least 3 - 4 videos that explain it on UA-cam. And your is always the most complete and relevant. Great job! I think you can consider write a book about system design focusing on interview purpose.
He is doing fantastic job. Ton to learn from the videos.
This is a really detailed walk-through of newsfeed system design. Thanks!
I came here after clicking on an UA-cam recommendation video. I am so glad I got this channel through the recommended videos. I referred so many videos and your video was the best explanation I came across for System Design interview especially taking Twitter as an example. Thanks so much for your videos. Hats off !!! great job. Such an amazing explanation. I wish I had teacher like you!!! Thanks a lot.
I am preparing for an interview of Amazon, and your video taught me a lot. Thanks and keep it coming!
Shen Chen please help me too.. Am. Also preparing for same
Rekha Mor good luck!
Thank you for posting design questions in such a fast pace. I really like your videos...Keep it coming :)
Absolutely love your work man. Gives so much more confidence when you mention what these companies are actually using. Highly, highly appreciated, thank you!
Just saw the Wpp video from 2 months before this. And the difference is enormous kkkkkk.
This video is much better. Good work and thank you for the video
Read "Grokking the System Design Interview" could not understand much and then came here, and everything made sense. Thank you Narendra for these great videos.
There is a lot of work done! You are amazing sir
Aaayee captain! Nice to see you here, your content is awesome as well. Fun fact, I listen to your podcast on Spotify daily while evening walks :D
I was truly amazed when i discovered your channel . Keep the good work mate!
Keep Coming. Really appreciate the efforts you are taking to make such valuable source of Information.
Narendra, I'm a big fan of your work. I want you to know that I really appreciate the time and effort that you've put into this. It has helped me a lot to improve my understanding of system design.
Best content so far I have come across in days. Really good!!
I have seen more than 5 videos and read many more articles. But yours one is the best and well detailed. Thank You.
This is so thorough and specific yet explained in a great way! Shows true mastery of the topic. Thank you very much for your work, really appreciated :D
Amazing !! 👍 Simple straight forward explanation, well structured in parts, well connected explained in a very nice clear voice. This is complete and comprehensive. I don't know of any video on these topics which comes anywhere near it. Great job man!! keep going !! You do us proud. 👍👍
Brilliant. Well done managing the details+clarity in 35 mins!
Thank you for explaining the overall system design in a such a clear, very easy to understand manner!!
Hey man! Great work! Well explained! Love to see more coming from you!
Now I understand the importance of reading books. I remember this celebrity example was provided in the book name "Designing Data-Intensive Applications: The Big Ideas Behind Reliable, Scalable, and Maintainable Systems". Great Work. More power to you,
Outstanding System Design video. I think this Twitter Design is more realistic than what other videos on the same topic show. Great work!
Many thanks for making this video :-) You start from basic and go up to advanced concepts in very a easy to understand manner.
Best Twitter system design video I've seen so far.
I think for every video you must have read lot of articles , book and compile all the information and delivered in 40 Mins. Keep up the great Job Naren.
Really like all of your videos. Thank you for doing the hard work and sharing your knowledge with the community.
Thanks Narendra....your videos are really useful. It is very difficult to get
such system design explanation with so much details.
Awesome one, mate.
Wonderful and neat explanation of such a large scale system.
Thanks.
There is lot of preparation that you do to come up with these videos. Excellent work!
Great explanations! The only additional things that I learned from other videos (of lesser pedagogical quality):
- Regional distribution of cached data (for Reddis) is done thanks to the Writer API (that writes the tweet in the primary region for Reddis + additional regions).
- in order to have quick response times between the client and the Write API, the client actually talks to a queue; and the write API picks up messages from that queue.
links to those videos?
On going through your lectures able to get horizontal approach on many new concepts . very good work. Thank you
very good compilation Naren, really like your videos as they are detailed and good quality :)
fantastic work bro. You have scaled to a new level :)
Thank you very much for the simplified explanation!! It cannot be any simpler than this.
very well explained, I could get every bit of the system and much better than many other videos on youtube.

I've seen so many system design videos and your's are the best. You know your stuff, you keep it to the point, go deep and overall really helpful. Awesome job and many thanks for all your work. A single video cannot cover everything but I would have liked to see how twitter shards users in this design.
@Prashant thanks, Yes Thats the problem. with my day job I dont have much time to make it a series of videos explaining everything / cover every bits and pieces so i keep it simple and important points only.

Really great video, in the upcoming ones could you spend some time explaining the intuition behind coming up with capacity & traffic estimates.
I am still at 7:45 but have to say you are very good technically ! Thanks a ton !
Excellent and thorough explanation!

Very happy to see you pasted design diagram image too.. (y)
I nailed Amazon system design interview question by watching your videos. Just wanted to say thank you and thank you.
keep it up bro. this is the nice video with very good explanation
Amazing job! It helped me learn a good deal.
Small nit pick, you want to reverse the order of your redis keys. +- is less efficient than -, think of redis keys as multi-column indices, if you put the random id in front your you effectively double the binary search time. The way you have it the order of your keys might looks like
Current Redis
---------------------
123-user
124-tweet
125-tweet
126-user
Should Be
----------------
tweet-124
tweet-125
user-123
user-126
If the ratio of tweets to users is not 1:1 you will increase the user lookup time by a factor of the ratio
In Redis is it hash-based lookup from K-V pair or does it use the binary search to find the cache names?
Bikas Katwal that’s a good point. Redis runs in memory, any kv store that uses disk behind the scenes is usually using b-trees
awesome description Naren .
Great stuff 🙌 Learned a lot.
you are great bro.. awesome video. thanks for helping out.
Great job. Please continue your work.
Well explained. Thank you for posting the video

Amazing Video.....Nice and simple explanation.
Super work bro. Thanks a lot
