> Reading columnar mega pages that are not contiguous could be slowed by the number of requests as each range of contiguous pages will requested separately. In fact, doing SELECT * can be 2x faster than doing SELECT c1, c2, ..., cN  (where N is a double digit number) if each column initiate a cloud read request 
> Such requests should be capped to a small number.
