This can happen as part of node bootstrap,repair or rebuild node.

Subject: Huge files in level 1 and level 0 of LeveledCompactionStrategy

I have a couple of SSTables that are humongous

-rw-r--r-- 1 user group 138933736915 Dec  1 03:41 lb-29677471-big-Data.db
-rw-r--r-- 1 user group  78444316655 Dec  1 03:58 lb-29677495-big-Data.db
-rw-r--r-- 1 user group 212429252597 Dec  1 08:20 lb-29678145-big-Data.db

sstablemetadata reports that these are all in SSTable Level 0. This table is running with

compaction = {'sstable_size_in_mb': '200', 'tombstone_threshold': '0.25', 'tombstone_compaction_interval':
'300', 'class': 'org.apache.cassandra.db.compaction.LeveledCompactionStrategy'}

How could this happen?
