> Scrub was intended to check a data file is not corrupted and to try to correct some form of corruption and discard the data when it can't repair. But we are now using it also for:
> * major upgrade, to have sstable in the new data format for streaming sake (that one could be "fixed" independently by supporting old format during streaming)
> * to force the compaction of existing sstables after changing the compression algorithm
> We should probably provide a separate tool/command for those two last tasks since:
> * we could have a better name, like upgrade_sstables or rewrite_sstables for that operation
> * we could avoid the automatic snapshot that scrub does (and is not expected by users for those operations)
> * make it slightly quicker/simpler by avoiding the corruption detection code
