> When looking at a problematic node I'm not familiar with, one of the first things I do
is check cfstats to identify the tables with the most reads, writes, and data.  This is fine
as long as there aren't a lot of tables but once it goes above a dozen it's quite difficult.
 cfstats should allow me to sort the results and limit to top K tables.
