Also related to this point, now I'm seeing something even more odd: some
compactions are way bigger than the size of the column family itself, such
as:
$ nodetool compactionstats -H
pending tasks: 110
compaction type keyspace table completed total
unit progress
Compaction draios message_data1 26.28 GB 118.73 GB
bytes 22.13%
Active compaction remaining time : 0h04m30s
It says the total is 118.73 GB, but that column family never got anywhere
close to that size, it has always stayed around ~30GB:
$ du -hs /raid0/cassandra/data/draios/message_data1-*
35G
/raid0/cassandra/data/draios/message_data1-ad87f550ea2b11e5a528dde586fa678e
