> Both approaches fails when you have folks with lots of followers The traditional mailbox architectural model can be improved via a few methods though to increase scale. 1. The entire tweet doesn’t need to be duplicated for each follower, only a lookup reference (“ID”) to the tweet. 2. Unlike in a traditional mailbox sense, each user’s timeline is a bounded collection. So rather than maintaining every tweet for every followed user in the timeline, it’s capped to the X most recent. |
