> the extension requires quite a large database (~15TB) Maybe I am missing something but how does a database which just needs to store video ID and a number become 15TB in size?
Round up to 500 raw bytes per row (perhaps including time/ip and other random garbage, plus indexes), 3x replication/redundancy or something, for 6 million users each having voted on 500 videos, and you're at 6TB; still some ways off from 15TB, but not insurmountably far.
(votes/user is rather tricky to get; but, as a bit of random garbage statistics math: YT gets ~5B views/day and has ~3B users; 6M downloads of the extension means ~0.2% of users use it, so 10M extension-user views/day = 15B over 4 years, or 2.5K/user; assuming 20% vote rate (rather high but lets say extension users care more for voting and/or watch YT more than an average person), that's 500 votes/user)
