No. is open to
track this but nobody is working on it to my knowledge.

Cassandra is fine with symlinks at the data directory level but I
don't think that helps you, since you really want to move the sstables
themselves. (Cassandra is NOT fine with symlinked sstable files, or
with any moving around of sstable files while it is running.)
