For the record and just my opinion : I recommend against paying this fixed cost when you don't need to. It is basically trivial to ascertain whether there is a new version of the SSTable format in your new version, without even relying on the canonical NEWS.txt. Type "nodetool flush" and look at the filename of the table that was just flushed. If the version component is different from all the other SSTables, you definitely need to run upgradesstables. If it isn't, you definitely don't. If you're going to run something which unnecessarily rewrites all SSTables, why not scrub? That'll check the files for corruption while also upgrading them as they are written out 1:1... =Rob
