Brandon Williams commented on CASSANDRA-3883:
---------------------------------------------
Optimally, we'd have a way to express "I'm at this column offset in this row,
give me the next X number of columns, even if it requires going to the next
row." But I'm not sure how to do that sanely, either. I know Jake is using a
special CFIF for hive to handle wide rows that basically just grabs one row at
a time and paginates it, which is fine if all the rows are wide, but will take
a performance hit if they are not. Still, that might be the best thing to do
since using get_page_slices is currently so hairy.
