Then you could use a LongType comparator for the columns and use the page

firewall related, in that I didn't have my messaging/data port (7000) open

What happens is that if you just autobootstrap without setting a token it
will by default bisect the range of the largest node.

Another thing to keep in mind when doing this with CQL is to take into
account the ordering partitioner you may or may not be using. If you're
using one you'll need to make sure that if you have a larger number of rows

I think you'd just be better served with just a little different primary

If your primary key was (user_id, created_at) or (user_id, created_at,

As Rob mentioned, no one (myself included) has successfully used shuffle in
