> Key: CASSANDRA-14330
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14330
> Project: Cassandra
> Issue Type: Bug
> Reporter: Aleksey Yeschenko
> Assignee: Aleksey Yeschenko
> Priority: Major
> Fix For: 3.0.x, 3.11.x, 4.x
>
>
> If there is an open range tombstone in an iterator, a short read protection request for it will include a repeat open bound. Currently, {{DataResolver}} doesn't expect this, and will raise an assertion, timing out the request.
> As this is a completely normal/common scenario, we should allow for this, and relax the assertion.
> Additionally, the linked branch makes the re-trhowing {{AssertionError}} more detailed and more correct: the responses are now printed out in the correct order, respecting {{isReversed}}, the command causing the assertion is now logged, as is {{isReversed}} itself, and local deletion times for RTs.
