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.
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!!
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!!!
When I research the design for a particular product, I watched at least 3 - 4 videos that explain it on RUclips. 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.
I came here after clicking on an RUclips 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.
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
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
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!
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.
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.
This is a really detailed walk-through of newsfeed system design. Thanks!
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,
Absolutely love your work man. Gives so much more confidence when you mention what these companies are actually using. Highly, highly appreciated, thank you!
I was truly amazed when i discovered your channel . Keep the good work mate!
Thank you for posting design questions in such a fast pace. I really like your videos...Keep it coming :)
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.
He is doing fantastic job. Ton to learn from the videos.
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
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?
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. 👍👍
Best content so far I have come across in days. Really good!!
Brilliant. Well done managing the details+clarity in 35 mins!
Hey man! Great work! Well explained! Love to see more coming from you!
Thank you for explaining the overall system design in a such a clear, very easy to understand manner!!
Outstanding System Design video. I think this Twitter Design is more realistic than what other videos on the same topic show. Great work!
Best Twitter system design video I've seen so far.
Keep Coming. Really appreciate the efforts you are taking to make such valuable source of Information.
There is lot of preparation that you do to come up with these videos. Excellent work!
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.
I agree with the comment from Atul.K.Yadav. Great Job Narendra. You are exceptional in your explanation.
This was very clear and simple to understand. Thank you so much!
I will call you SIR. You are an amazing teacher. Best explanation.
Thank you very much for the simplified explanation!! It cannot be any simpler than this.
Really like all of your videos. Thank you for doing the hard work and sharing your knowledge with the community.
On going through your lectures able to get horizontal approach on many new concepts . very good work. Thank you
fantastic work bro. You have scaled to a new level :)
Many thanks for making this video :-) You start from basic and go up to advanced concepts in very a easy to understand manner.
Thanks Narendra! All your videos are nicely articulated and informative. I am a fan :)
the best video on twitter system design I've ever seen before in my life
Well explained with impressive attitude 😉
We're not curious but more eagerly watching how you are doing and finally you done it..😁
Thanks much bro 👊 for your effort and efficiency....😊
Please make more videos and spread your wisdom.. so early you gonna crossing in millions subscriber..... Congrats in advance 💐
Thank you also for mentioning the concepts involved (eventual consistency, gather & scatter, fan out, ifti)
very good compilation Naren, really like your videos as they are detailed and good quality :)
Great clarity in the explanation.. demystifies so nicely
Thank you for putting up this tutorial! Study vidoes like this and then practice at Meetapro with mock interviews will help you land multiple offers.
Fantastic Job Narendra...keep it up...your videos are really very informative and helps to understand core concept of system .Thanks
Thank you for your help, your videos are really very helpful in understanding the real life design system. Thanks much :)
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.
@@TechDummiesNarendraL Nice videos. Now extend them in details please for each component.
Would help a lot to everyone. Again Thanks for everything.
very well explained, I could get every bit of the system and much better than many other videos on youtube.
Your videos are jammed with so much useful knowledge... It's just wonderful... Big thanks
This is an amazing video! extremely detailed & well designed... Thank you for this... (Subscribed!)
You are so amazing and knowledgeable!! Thanks for sharing these informative Videos!!
Good job Naren. This design video is very well done
super introduction to the architecture! thank you
Told all my friends. You are doing a great job.
One of the best videos of its own kind. Thank you!!
Hey, Thank you so much all your knowledge sharing. I am able to perform very nice in all my interviews. Keep up the good work. More power to you.
Keep rocking!!!
Really great video, in the upcoming ones could you spend some time explaining the intuition behind coming up with capacity & traffic estimates.
Amazing work, crystal clear concepts. Thank you!
learned a ton❤️ and btw your blue bird drawing is the best lol
Thanks for spreading your knowledge man. Greetings from Egypt.
Crystal clear system design. Thanks for your time and effort 👍
I am short of words .. Awesome stuff man !!
Thank u so much for such a detailed explanation of each important topic
I am still at 7:45 but have to say you are very good technically ! Thanks a ton !
Very happy to see you pasted design diagram image too.. (y)
Amazing video , I like how you explained the fanout concept and how you explained that some of the daemon processes are delegated to streaming technologies like kafka. Would you recommend for a start-up that is trying to save on hosting , to use background jobs/workers instead of using Kafka or Apache Storm?
The best video i have ever watched on twitter system design
Great , You are helping the community a lot
Great video, thanks for the simple and clear explanation of concepts
I am gonna wish you teachers day forever . Thanks for awesome tutorial :)
Simply awesome. Keep up good work.
Hi Naren.... Nice and really informative videos !!! Would request you to put videos for 1) Travel Sites like makemytrip 2) Stock Exchange sites like : Dowjones , Sharekhan 3) Banking Sites - Barclays,ICICI.
I nailed Amazon system design interview question by watching your videos. Just wanted to say thank you and thank you.
Hey Narendra, thanks for this solid work! Could you also make videos about the google's GFS, BigTable and Map Reduce paper ? I think these materials will be useful as well!
You're a great tutor. Keep up a good work!
Hey Narendra, It's really a great explanation and it couldn't be more better. Also this makes perfect sense to me. The problem which I'm facing right now is with microservice architecture. I mean if the same has to be designed in a proper microservice architecture, how we are going to do that?
Like in this case the same Redis cluster is shared across different services, which means tight coupling. I would be really thankful if you make a system design video of any system by following microservice architecture. I mean each module will have a context bound and data ownership.
And if you already have any video available for the same, please point me to that.
Thank you, keep up the great work!
Amazing Man! instantly subscribed. Godspeed to you.
Hi Naren, do you have any suggestion for a book/reading materials for learning high level design. What I am looking for is a systematic approach towards designing and basic principles listed down somewhere. Great videos though. keep doing them.
Bravo. This is one of the better system design videos.
@Naren L: Simply the best and smart. You have acquired such a great knowledge. Wow !!!
Very good explanation. Extremely informative. Thank you :)
Great video.
I see timeline problem being solved differently using/building time-series DB and distributed caching based on locality of reference. Please share your thought/view.
The great information on twitter architecture....Keep up the good work.
Thanks for all the hard work that you put in creating such quality content. I have a request, can you suggest me some reference to resource explaining the system design of Facebook's like system and how to find the number of viewers of a video stream in real time. Thank You.
This gave me a huge insight, thank you.
Great Efforts Sir!. CAn you please also leave links or show practical videos which demonstrates the concepts you are using individually. Example a sample explanation on practical working example of a demonstrating Kafka, Apache STORM, or REDIS etc
awesome description Naren .
awesome video man ... ! this is relevant to any social media platform design like FB , Linkedin , Instagram.
Thank you Narendra, your videos really helpful
keep it up bro. this is the nice video with very good explanation
Well explained. Thank you for posting the video
Hi Narendra, Really liked your video in which you have made things very clear. Just one question about the choice of the Database - why did you choose Cassandra over opther options like mongodb aur a graph database (which sounds like a good option for a social networking website)?
Amazing videos! Congrats! One suggestion could be to use a different microphone to reduce echo and noise and make your voice more clear since for me it seems that every word you say is important! Keep the good work!
Excellent and thorough 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
Good job man. Not sure if I missed out something but I wanted to ask how images are handled. Thanks.
you are the gem master and your videos are gems
