--------------------------------------------
Summary: Expired cells not converted to deleted cells during
cleanup/scrub/compaction (sometimes)
Key: CASSANDRA-6844
URL: https://issues.apache.org/jira/browse/CASSANDRA-6844
Project: Cassandra
Issue Type: Bug
Reporter: Aleksey Yeschenko
Assignee: Aleksey Yeschenko
On read path, we intentionally read expiring cells as expiring cells, never
converting them to tombstones, to return consistent results to the clients.
For compaction/cleanup/scrub we don't care about that, and are supposed to make
the conversion as an optimization. However, somewhere along the way it got
lost, and SSTII doesn't always do it now in 2.0 (and never does it in 2.1).
SSTI.getColumnFamilyWithColumns() passes the correct expireBefore(), but
SSTI.next() does not, and while we use both in 2.0, depending on the some
factors, in 2.1 we only use SSTI.next(), and SSTI.getColumnFamilyWithColumns()
is actually dead code (I will remove it during the 2.1 merge).
