Sylvain Lebresne commented on CASSANDRA-1963:
---------------------------------------------
.equals() with no other changes won't work because in sstable.descriptor, the
directory is an absolute path.
We could construct descriptor with an absolute path too but I haven't found any
satisfying way to do that
(DB.getDataFileLocationForTable() may not return the right path if you have
multiple volumes). Hence the
endsWith.
> Allow user to specify files to compact through JMX

> 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.
