Your videos are truly underrated - crisp and clear. I believe your channel has a lot of potential, and your website has a wealth of content that could be very helpful for my interview preparations. kudos to your expertise and hard work in content creation!!
Very valuable content! You've done tiny url, a social media and a search engine. Now it's time for an in depth ecommerce system design video. I would love to see that!
@@TechPrepYT Great. We would love to see how you discuss the design of the rest api and how you structure the architecture of all the different services for the cart, product listings, user accounts, whishlist, etc. I would really love if you can talk a bit about the product recommendation system, infinite scroll pagination in the rest api, etc.
Yes the video will definitely cover all of those services, but it mightn't just be a REST API. I most likely will also include a GraphQL API to handle the nested nature of some of the data (e.g. products) as well as pagination etc.
Can see your channel growing big with content like this, Im a recent grad of computer science strugging with technical interviews so stuff like this is really helpful
Yeah will do that would be great! I find myself feeling like a bit of an imposter I managed to get a first but I struggle with stuff from my 1st year so been trying to go back over this stuff so I dont get caught out in interviews@@TechPrepYT
Thank you for your videos, they’re really informative. You deserve many more subscribers! Just a small bit of feedback, there some background noise like tapping which is a tad jarring when using headphones.
Great video but maybe a little extra improvement could be to disconnect the user from the profile. So have one sso service for handling users (security, login/register, user info,... ) and one profile service for storing the profile info like in this case the follower stuff etc. and use this for the other Services and reference the connected user id in the Profile. This could allow for a user to have multiple profiles on a single account and to have the whole security logic be somewhere else for better Performance and maybe when creating a new system to use the same sso for login with your account
Great comment! Yes 100% agree this would be a very important service to implement to make the system more robust and extensible. If you were using a cloud provider they have services like AWS Cognito which would help you implement this. This is definitely something worth including in this system design!
Great solution. I didn't fully get how the hybrid push and pull model would work. Let say i follow 10 users and 2 of them have huge followers. It seems the system would build my feed with tweets from the 8 less popular users I follow. Then what is next when I retrieve my feed? Can you please elaborate more? Thank you
In this Data model, should we keep followers in a different table? This would make followers table heavy if we keep all the users data in this table, retrieval would be time taking. What if we maintain a column in user table to keep the list of followers?

This was cool
Was expecting some Machine learning aspect
How does the tweet service know which cache server to store a particular user tweets into in a push model?
