[jira] [Commented] (CASSANDRA-3459) Remove CF name from SSTable

Sylvain Lebresne commented on CASSANDRA-3459:
---------------------------------------------
Sorry for the dumb question, but is there any other motivation to remove the cf name from the file name other than "we wouldn't *have* to anymore"?
Because even if we don't have to, I think it's still fairly convenient to have it in the file name for all of the cases where you move some sstables out of the initial repository. Or to reformulate, I'm fine with making it so that Descriptor don't rely on the file name to decide from which CF the sstable are for if that's what is proposed here, but I'd be in favor of keeping the file name as it is unless we have a compelling reason not to.

---------------------------------------------
Is it really harmful to leave the CF name in? Consider if you have 20 CFs and somehow lose the inode for one of the dirs and it's moved to lost+found. Now there's no simple way to figure out what it is and move it back.

-------------------------------------------
I'd kind of rather do this as part of CASSANDRA-2749 rather than separately, but if it's a Big Deal we can split it out.

-------------------------------------------
Relatedly and more important is CASSANDRA-1983 IMO, as that would make it a lot easier to perform and test sstable based disaster recovery.
