That is a very important part of TinyURL design. You can understand that flow here at 32:12 - kzbin.info/www/bejne/eX_Mp4OlYpKZaK8 .

Thanks for reaching out @HealthHacker4U ! We are glad you are loving our content. We will soon be adding more buzzwords videos.

What exactly are you interested in knowing? The inner functioning of Message Queues?

Good question! When we mention Facebook's 30,000+ servers, we’re referring to all the servers that handle various tasks across the platform, not just those fetching data. Yes, some servers amongst these 30,000+ will be fetch data from the data layer; while others will process user actions like 'likes'; some will run machine learning algorithms for personalized feeds etc. The idea is to explain, how much horizontal scaling could be needed depending on the number of users using our platform.

@adityamehta543 That is a wonderful question first of all. The answer to your question is at 12:14 where we talk about Resumable URL. Server sends a Resumable URL to client which it uses to upload the content. Now, even if it is 2 hour long video it doesn't trouble us. The upload gets paused and resumed based on the internet connection. But why aren't we chunking at the client at the very first place? Well, chunking on the client can be resource-heavy, especially on low-end devices or poor networks. By chunking at the server, we simplify the client’s workload and get better control over how we process and store the video. That said, client-side chunking can be useful in some cases, especially for large uploads. It’s a trade-off depending on the use case.

​@@sweetcodey Thank you so much for answering the question! This truly helps and also the video explaination is amazing. I have few more concerns also, if you can take it up-: 1) Can you also talk little bit about search functionality here, if we have to include search service, how would it interact with elastic search and will elastic search get the data from video db and then index on it and return ? Just how it will look like if you can tell over text only. 3) Uploading a video is a functional requirement , but notification is also functional requirement? Thank you so much and sorry for bombarding the comment section with questions. The video is very detailed and I am learning a lot from it.

​@adityamehta543 Thanks for the appreciation! 1) Regarding the search functionality, it might be more than what’s needed here. In an interview setting, we recommend focusing on core features like upload and stream. Search is an extensive topic on its own, and we’ll dive deeper into it in future KZbin videos and courses at sweetcodey.com. 2) As for notifications, they can be a nice touch if the interviewer brings it up, though it's not essential. It wasn’t part of the original functional requirements, but we think it’s a valuable addition if time permits.

Glad you liked it Apurv.

Thank you
