That information was removed, because it was really meant to be used for a handful of internal tasks, most of which were no longer used. The remaining use was cleaning up compaction leftovers, and the compaction leftover code was rewritten in 3.0 / CASSANDRA-7066 (note, though, that it's somewhat incomplete in the upgrade case , so CASSANDRA-13313 may be interesting to people who are very very very very very very very sensitive to data consistency)
