just a thought, not all 5GB is consumed in a second when a viewer watches. streaming is going to be in packets that might be much smaller than 5GB. so the server side estimation for bandth of 10TB/second seems to be over estimating. also you talk about storing uploaded file in different formats, that would mean your initial analysis of 5PB will increase to 10 or 15 PB depending on how many formats you store the video in.
One of the finest explanation I have ever seen , I am following a more than dozen of System design channels but the way putting the flow is at the top, Please make more such videos for other topics like chatApps, Google Docs ..etc
great video -- I would add -- Video files specifically are usually served using MPEG DASH or HLS -- where the same content is saved at multiple resolutions so it can be served to multiple clients depending on b/w.
You are amazing !! Streamlining all topics , explaining everything in such a short time. No one does like that .. appreciate your hard work. Thanks for the videos..
Hi Pratiksha, thank you so much for the awesome content! I started using excalidraw. But I could not find a library/option with a database table (such as you used to draw the video metadata table). Can you please share the name of the library that has it?
Wow, your System Design videos are the best I've found on RUclips. I love how to the point, concise, yet through the videos are. I also like how you use a realistic visual tool as well. Thank you for putting the time to make these!
Fir video URL table, if we have 10M video, each video is lets say 2HR and 4GB in size, if we split it into one minute chunks, each is of 34MB, i split video in 5min chunks each of 170MB, so 24 chunks per video. 10M * 24 = 240M, I think thats a huge data to store in SQL, we would need to worry about sharding here. ALso the files are already grouped, Using NoSQL DB here would be better, for each video we can store chunk info in single object
Hey Pratiksha. Great videos and explanation. One query- you say that you will use a SQL database for Video Metadata and a nosql for some other info... Is it fine to use multiple DB types in a single system. I know you can, but wont it make the whole thing very complex?
Hello Pratiksha, really appreciate for the level of content you are sharing for everyone…just ❤ it, wondering, do you have a plan to continue this series with new contents on online food booking, delivery system, online betting system, cab booking system etc ?
hi madam, I have got a doubt on Bandwidth estimation 6:58 , we are not delivering 5GB in one click, it's depends on video resolution, isn't it? Lot more to cover, features like comment, like, share, subscription, save, playlist, community, live streaming and so on.. never ending
Didn't get your Bandwidth calculation, 2000 QPS * 5GB,. I don't think 5gb is required, the video will be downliaded in chunks of may be 100MB each, as and when user plays the video. CMIIAW.
Awesome Explanation ! Thanks a lot for the efforts you put into these videos. I have seen multiple system design related channels, but you follow a very systematic approach to solving the problems with great detail to each small thing. Maybe you can give a shot at Low Level Design videos along with these high level design videos too.
Thank you so much for sharing that! Comments from you all keeps motivated to make more videos. In the future, i would be happy to take a shot at LLDs as well!
Just focus on system design, that’s enough for us. We are not at all interested in interview setup, just don’t waste your energy on shooting in two dresses and then mixing.
That's great call out! Thank you for doing that. You could certainly add that to your design. When you are doing the interview, you will only have 45 minutes to an hour, so you can focus only on so many things. You don't want to get too detailed upfront and not be able to complete your design in given timeframe as interviewers may be judging your time management skills as well.

Upload API param should also contains USER ID, ,description and other relevant details as this is the first point where the video comes in picture so we should have that parameters also in api??
Hello Deep Kiran, Video Id can be numeric/alpha-numeric or UUID. There are multiple ways we can auto-generate a unique id for each video. Part ID will maintain the sequence of the video. Part ID 1 - will be the first part of the video, Part Id 2 will be the second part of the video, and so on! I hope this answers your questions!
I really liked the estimation simplification you did there. But I do not agree that category would be a string., categories are probably limited, so they would be a foreign key to another table. It would also be a very big red flag if you talk about mp3 for video and not mp4. Mpeg layer 3 is only for audio.
probably the most effective system design video I found on RUclips.
Thank you, Ali! I appreciate the feedback! Feel free to share it with your friends who may find it useful!

interviewer was so damn real 🤣, btw this is the best video i have seen , please keep continuing your work

Glad it was helpful!
I would really clap for you. This kind of explanation is very rare on youtube.
This is the first time I leave a comment, thanks so much for making these videos, they are one of the best system design videos I found on RUclips!
Thank you very much!
Mam just perfect design ever saw I'm a fresher idk about this before this is the first video on system design for me i think i did the best choice
great video -- I would add -- Video files specifically are usually served using MPEG DASH or HLS -- where the same content is saved at multiple resolutions so it can be served to multiple clients depending on b/w.
really nice way to put things up in an system design interview
15:24 we should probably do the checks first ( inspection etc ) before splitting to reduce time if any unwanted files / virus are uploaded

Great explanation!! Learn a lot, Can you make a seperate video on which DB (SQL vs NoSql) to use in different scenarios .
Great suggestion! Added to my list! Thanks

Neat explanation. This gives us a template on how to approach system design questions. Thanks Pratiksha.
Glad you liked it
I've been watcNice tutorialng tNice tutorials and you inspired to try to make soft so I thank you
You catch on really fast, it seems complex but once you learn the basics it pretty much branches into experintation
Thank you so much!!! It did work and took less than 5 minutes!

Glad you enjoy it!
Do you think, in the data model design section, one should also mention relationships and cardinalities between entities?
Thanks 👏 great explanation 👍
Thank you, Karthikeya !
Really nice videos on sys design, would love to see more
More to come! Thank you for the feedback
concepts finally line up in my brain and...well, who knows? Maybe I'll be able to make sotNice tutorialng now.
Very nice . 👌

Exceptional Video Pratiksha 👍🏻 Hope to see more such content
Thank you Ankur! I will try my best to bring good content.

Great Video. Each topic is explained well, Looking forward to more videos
Thank you so much! More videos to come!
great video. thanks!
While doing storage estimations you have not taken into account the different file formats for each video..is that a miss?
That's great call out! Thank you for doing that. You could certainly add that to your design.
When you are doing the interview, you will only have 45 minutes to an hour, so you can focus only on so many things. You don't want to get too detailed upfront and not be able to complete your design in given timeframe as interviewers may be judging your time management skills as well.

Yeah too, exceptt I feel the exact sa way i did.

I liked the way you explained the designing so easily with UML diagram.

one question! how will order of split videos be mantained? how will video id be decided?
Hello Deep Kiran,
Video Id can be numeric/alpha-numeric or UUID. There are multiple ways we can auto-generate a unique id for each video.
Part ID will maintain the sequence of the video. Part ID 1 - will be the first part of the video, Part Id 2 will be the second part of the video, and so on!
I hope this answers your questions!
