Hi I'm wanting to get more compression because sequential rows tend to be highly correlated. So I'm wanting to do something like running every block of 100 rows through an LZ compress function before storing it. With my data, I should be able to get around 80% compression. This is similar to how BigTable and Hadoop store their data.
