> CompactionManagerMBean exports the number of bytes compacted and the total number to
be compacted during a given job, but I don't believe it says what sort of compaction it's
doing (anti-compaction, validation compaction, index build, or an SSTable build after receiving
an incoming streamed file).
> Is it possible to have multiple threads going in the compaction manager?  (It doesn't
look like it, but I don't see any explicit maximumPoolSize setting.)  If so, cassandra should
also expose all ongoing compaction tasks and progress for each individually.
