> When you don't have enough space to perform a major compaction but know there
> would be space to reclaim, the actual algorithm (discard the biggest sstables
> one by one until it fits) may not be helpful.
> This is even more true now that minor compaction can remove tombstone and more
> importantly with expiring columns (for which the compaction of a single
> sstable can make sense).
> This ticket proposes to expose a simple function through JMX to allow the
> submission of a compaction on user-specified sstables.
