Thank you for sharing your technique.

I also think that a diferent model of compaction could be useful, esp
in situations when the normal and nice compaction (the one which gives
place to read/write to ocurr) is not enough to recover or when you
have small windows of low activity with a lot of unused resources in
the cluster.
