Tyler Hobbs commented on CASSANDRA-9171:
----------------------------------------

I meant deleting non-PK cells.  That wouldn't affect the number of rows that 
get returned in the paging result, but it could theoretically expose a bug in 
how we process the cells internally.  (They get counted, grouped, trimmed, etc 
in a lot of places.)

> Deletions can easily impact paging (see CASSANDRA-8490 for an example).  We 
> should improve the paging dtests to include various kinds of deletions: 
> partition-level, row-level, and cell-level.  The tests should also exercise 
> deleting enough contiguous partitions/rows/levels to fill an entire page.
> Assigning to [~rhatch] for now since he created the original paging tests, 
> but I can reassign this if needed.
