Amazing explanation sir.

Would like to know how FB store likes and comments.
Suppose user from India likes a video, and another user from the USA likes the same video, are they stored in same place or in a sharded db (country wise), would like to know your perspective

@ByteMonk dank video, very clear and concise but I've got a question: at 8:20 you say we're tasked with finding all the videos with a certain number of likes. Do we really need to go through ALL of the metadata if we're just looking for the condition "number of likes >= [some amount]"??
