Marcus Eriksson commented on CASSANDRA-4766:
--------------------------------------------
need to mark the sstables as compacting before creating SSTableSplitter in
StandaloneSplitter (cfs.getDataTracker().markCompacting(sstables)), otherwise
it fails with:
Exception in thread "main" java.lang.AssertionError:
/var/lib/cassandra/data/Keyspace1/Standard1/Keyspace1-Standard1-ic-3-Data.db is

ot correctly marked compacting

> Sometimes you run into a situation where your sized tiered SSTables get to be
> a funky size. Maybe a repair starts this or you were forced into a
> compaction. In any case we should be able to anti-compact a table, since
> anti-compact is a bad word lets call this reverse compact. This could be done
> online or offline. Closely related is SSTables cound have a max size. Leveled
> is not right for everyone.
