we are having the problem where we have huge SSTABLEs with tombstoned data in them that is not being compacted soon enough (because size tiered compaction requires, by default, 4 like sized SSTABLEs).  this is using more disk space than we anticipated.

we are very write heavy compared to reads, and we delete the data after N number of days (depends on the column family, but N is around 7 days)

my question is would leveled compaction help to get rid of the tombstoned data faster than size tiered, and therefore reduce the disk space usage?
