the reason for this all test i conducted i we have a prod cluster of 2.1
where twcs was defined on many tables a few months ago (all tables with
read repair setting disabled, also speculative retry disabled), and looked
very good. a month ago we noticed most of the servers had their data all in
newly created sstables (looking like plain size tiered), and we are not
sure what caused it (nobody ran major compaction on all the tables on all
those nodes). i was unable to find a bug in the cassandra jira that would
explain how this could happen. is there something you know that might cause
this (again, this is 2.1, with your jar, might be something specifically
there). thanks
