Jonathan Ellis commented on CASSANDRA-5395:
-------------------------------------------
... And pushed a 3rd commit applying the fix in patch to to
ParallelCompactionIterable.
This also has the side effect of switching from TSM to ABSM for PrecompactedRow
and ParallelCompactionIterable, so there may be a performance improvement.
> Compaction doesn't remove index entries as designed

> Key: CASSANDRA-5395
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5395
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.2.0
> Reporter: Jonathan Ellis
> Priority: Minor
> Fix For: 1.2.4

> PerColumnIndexUpdater ignores updates where the new value is a tombstone. It
> should still remove the index entry on oldColumn.
> (Note that this will not affect user-visible correctness, since
> KeysSearcher/CompositeSearcher will issue deletes against stale index
> entries, but having more stale entries than we "should" could affect
> performance.)
