A diagnostic tool that reveals blocking SSTables that prevent an SSTable from dropping.

During compaction, the database can drop entire SSTables when they contain only expired tombstones and if it is guaranteed to not cover any data in other SSTables. This diagnostic tool outputs all SSTables that are blocking other SSTables from being dropped.
