Sylvain Lebresne updated CASSANDRA-4766:
----------------------------------------

    Attachment: 4766.txt

Attaching rebased patch (against 1.2) for the sstablesplit offline tool mentioned above. Seems
people have had some use of it, so it's probably worth committing it officially.

> 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.
