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

We haven't done any of those recently, on any nodes in this cluster. Would a major compaction
through 'nodetool compact' cause this? (I think I may have done one of those.)

Subject: Huge files in level 1 and level 0 of LeveledCompactionStrategy I have a couple of
SSTables that are humongous

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?
