--------------------------------------------
Summary: Bugs handling range tombstones in the sstable iterators
Key: CASSANDRA-13340
URL: https://issues.apache.org/jira/browse/CASSANDRA-13340
Project: Cassandra
Issue Type: Bug
Reporter: Sylvain Lebresne
Assignee: Sylvain Lebresne
Priority: Critical
Fix For: 3.0.x, 3.11.x
There is 2 bugs in the way sstable iterators handle range tombstones:
# empty range tombstones can be returned due to a strict comparison that
shouldn't be.
# the sstable reversed iterator can actually return completely bogus results
when range tombstones are spanning multiple index blocks.
The 2 bugs are admittedly separate but as they both impact the same area of
code and are both range tombstones related, I suggest just fixing both here
(unless something really really mind).
Marking the ticket critical mostly for the 2nd bug: it can truly make use
return bad results on reverse queries.
