What are the things to watch out for with big nodes

Hi,

If I have a cluster with 15-20T nodes, somethings that I know will be a
potential problem are

   - Compactions taking longer
   - Higher read latencies
   - Long time for adding/removing nodes

What are other things that can be problematic with big nodes?

Regards
Anand

(some details slightly out of date by now, I should try to update it)

Honestly though, I don't recommend going for nodes that big unless you
want to spend time dealing with issues you'll hit.
