Alan Boudreault commented on CASSANDRA-9171:
--------------------------------------------
Tentative PR for these new tests:
https://github.com/riptano/cassandra-dtest/pull/253
I have an issue with the last test (test_failure_threshold_deletions), not sure
why yet... will investigate more tomorrow. Here's the traceback:
{code}

The code fails even with a higher timeout (tried 90,200...). at this line:

> Add deletions to paging dtests

> 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.
