>The part about downloading entire databases to view your subset of the data. You're not doing this though you're downloading the entire database to verify the subset is true and you're using blocks because adding single transactions at a time when you need to have known ordering amongst a lot of participants leads to a lot of overhead that is removed by batching.

And yes I just made up that I worked in ETL at MS a department pretty much no one that hasn't worked in knows exists.
