Sylvain Lebresne commented on CASSANDRA-15897:
----------------------------------------------
I wrote a patch for the Gossip option discussed a while back. It's
[here|https://github.com/pcmanus/cassandra/commits/C-15897-3.0] and should be
pretty complete as far as refusing `DROP COMPACT STORAGE` until no nodes have
2.x sstables anymore goes.
I didn't got to updating {{upgradesstable}} to allow migrating 2.x sstables for
potential users that have already cornered themselves. And I'm afraid I'm
unlikely to have time for that in the short term.
So if we're ok with pushing update to {{upgradesstable}} (or {{scrub}}) to a
followup (I could argue that no user has complained about this yet; maybe
no-one has run into this yet), and are still ok with the Gossip approach, then
the path is more or less ready for review.
If we prefer having the {{upgradesstable}} change in this ticket however, I
cannot make promises on how quickly I can get to it (but I'm happy to hand it
over).
