Do you remember this part in the book "Designin Data-Intensive Applications by Martin Kleppmanns" about how twitter approached home timeline feature?
What they basically did, that instead of querying DB for all the tweets you follow - they are doing push approach, so you are basically reading from queue that is getting inserted when your followee pushes new tweet. One thing that for celebrities they left "query" approach.
I found the conference where it is explained with data, all path, problems, etc, very interesting:

Pretty weak explanations I would say. Stuff is either very simple and don't need expl but they do provide it, or very hard, and it is badly explained.
Especially analyzing recurrences. These guys didn't even mention anything about derivation and equations, and wops, here you are some random numbers out of nowhere proving something
