This is really useful data, Shawn, thanks! It's particularly interesting 
because the numbers are in the same ball-park as a project I'm considering.

Can you clarify one thing? What's the relationship you're describing between 
MySQL and Solr? I think you're saying that there's a 80TB MySQL database, with 
a 100GB Solr system in front, is that right? Or is the entire 80TB accessible 
through Solr directly?
