      Description

      sstable filenames look like CFName-1569-Index.db, containing an integer for uniqueness. This makes it possible (however unlikely) that the integer could overflow, which could be a problem. It also makes it difficult to collapse multiple nodes into a single one with rsync. I do this occasionally for testing: I'll copy our 20 node cluster into only 3 nodes by copying all of the data files and running cleanup; at present this requires a manual step of uniqifying the overlapping sstable names. If instead of an incrementing integer, it would be handy if these contained a UUID or somesuch that guarantees uniqueness across the cluster.
