i believe using an elastic search on the metadata db, would be much more helpful for searching /fuzzy searching.
Why not use a No SQL based DB while uploading videos? We wouldn't have to do the extraction in that case right? We can simply just work with the meta data DB in JSON format.
Thank you. Awesome interview
Great video. I am new to system design, just watching for fun. I was not satisfied with the search deep dive, I don’t know how it’s actually done, but I feel this would not be a convenient way, please correct me if I am wrong. And apart from that I also am unsure why he replicated the video to another CDN, how would that help 37:13 ? Could anyone please answer my questions?
thank you good design
He kinda got stuck between system design and low level design. You probably don't need to go to a much deeper detail in system design
Too much time into math and numbers??
Yep. And all in vain. He forgot about trans-coding and storing one video in multiple formats. 100MB / vid is way too humble of an estimate.
@@MinekEzQM: Yup he should have multiplied the total size by 10. Roughly 3 formats with 3 times replication.
