A Detailed Five Step Twitter Scaling Plan

To do the writes requires a lookup. To do a read requires a lookup. That's how sharding works. If not a lookup, then a hash.

This doesn't even get into the complexity of scaling your model from 1,000 or 10,000 users where your brute-force methods seem like they will work and applying it to 10,000,000 users where your model will die a horrible death, kinda like Twitter is today.

uhh... yes it requires a lookup. There is no problem with that since the lookup is not centralized but local. How... read about terracotta. No I dont work for the company just use their open source product.
