Though you’re correct that we can store the timestamp in a tuple and sort based on it, but running that query will be a costly operation.](https://hashnode.com/posts/how-twitter-generates-millions-of-unique-ids-per-second/61fc9eb18d15cb3e7ce5fd4e/comment/61fcac0efd8b083e57289c7e#reply-61fd6069fd8b083e5728b241)
