Thank you Gaurav for creating such a thorough resource for free and FreeCodeCamp for bringing it to millions of learners like me :)

      That is what system design is all about. It's meant to be understood by the layman. Surprisingly the most important part of programming is not in writing the code rather it's solving a problem using logical sequence that captures everything problem solution(system design). If you are not good at this then programming may not be for you!

    For me, it is not about SQL or noSQL
    It is more about:
    - Is it cheap? is it scaleable? at this stage of the project can I utilize my available resource?
    - Do we need schemaless/no schemaless, usually because of shameless, the database needs to take more space for storing and is slower at execution. Like dynamic-typed langue vs typed language.
    - Can I make relationship ? (typically the NoSQL is considered weak relationship, BUT YOU CAN STILL MAKE RELATIONSHIP. PLUS, BECAUSE OF SCHEMALESS YOU CAN EMBED DOCUMENT FOR MAKING THE RELATIONSHIP AND MAKING THE QUERY FASTER WITHOUT JOINING ACROSS TABLES )
    - How about its built-in function? it is usually better if you make the computation on the database instead of pulling it down to the server and computing and of course, you don't have to re-develop that function
    - The last one, of course, which type of database is more familiar to my team

    • @domisPL_01

      In terms of databases you really only have a few types, NoSQL, SQL, and in-memory. The brand of the db is almost irrelevant any decent engineer should know how to work with any of them.

    Great video. 1:18:43 - if going with variable frame length, then, if a frame is extended with absolute start position attribute, it becomes possible to do binary search within frames array for timestamp, instead of linear iterations ( O(log n) vs O(n) ). With fixed frame length even better, instead of iterations just divide timestamp by frame length, and we have a frame index in O(1).

    For "Go back to video and watch from timestamp", couldn't it be `play(user, videoID, 0)` where if it is 0, you check your cache to see if the user saw it previously?
    I also think that watched video shouldn't be a separate object because it doesn't make sense to create a new object every time a user watches a video. Instead, I think there should be a database table for watched videos with userID, seekTime, and videoID that can be queried in the VideoConsumingService.

    It's a pity that nobody helped the instructor get set up with proper audio. Long courses & videos are fatiguing to listen to when audio quality is poor. This matters to the mission of freeCodeCamp. Proper mic'ing is easily within reach economically these days, and audio engineering, acoustics, and home audio recording technology are not particularly complex topics for those with a STEM degree who've had the standard classical physics series.

    i have 3 questions!
    1. when commenting on a video.. why is the author's name sent in the POST, if the system already has it? (by processing the token on the header of the POST request)
    2. why does the user (after closing the window) ask for the timestamp, and then make another request with that value? the way i see it the server already has that data too.. it could directly return the videoframe on the 1st request
    3. and the last one... how is it possible that when commenting, the ID of the comment is sent in the POST?
    thats the most weird of all.. it is not even saved in the database yet. it doesn't have an ID. or even worse.. would't this lead to duplicate IDs if 2 users comment at the same time?
    am i sharper than normal today, or am i missing something?
    excellent video! learnt a lot from it , thank you very much 🙏

    Just starting to watch this video, the audio quality seems really off. maybe it's just me?

    thanks, great video, probably coding is not a part of a system design and not sure about spending that much time on the specific use cases, because I'm guessing each use case could be a separate system or described as a separate system design
