Compaction doesn't clear out expired tombstones from SerializingCache
---------------------------------------------------------------------
Key: CASSANDRA-3921
URL: https://issues.apache.org/jira/browse/CASSANDRA-3921
Project: Cassandra
Issue Type: Bug
Affects Versions: 0.8.0
Reporter: Jonathan Ellis
Priority: Minor
Fix For: 1.1.0
Compaction calls removeDeletedInCache, which looks like this:
{code}
. public void removeDeletedInCache(DecoratedKey key)
{
ColumnFamily cachedRow = cfs.getRawCachedRow(key);
if (cachedRow != null)
ColumnFamilyStore.removeDeleted(cachedRow, gcBefore);
}
{code}
For the SerializingCache, this means it calls removeDeleted on a temporary,
deserialized copy, which leaves the cache contents unaffected.
