Priority: Minor (was: Major)
> During garbagecollect use index check for tombstone removals
> ------------------------------------------------------------
>
> Key: CASSANDRA-14945
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14945
> Project: Cassandra
> Issue Type: Improvement
> Components: Compaction
> Reporter: Vitalii Ishchenko
> Priority: Minor
>
> nodetool garbagecollect command may be further improved to actually remove
> more tombstones. Right now bloom filter is used and may give false positives
> preventing tombstone removal if min table timestamp is less than tombstone
> timestamp.
> Disabling bloom filter should do the trick, but currently there is a bug in
> compaction with bloom filter turned off CASSANDRA-14944
> As improvement index can be always checked if garbagecollect compaction is
> done
