| SSTableOfflineRelevel |
Create a decent leveling for the given keyspace/column family
Approach is to sort the sstables by their last token
given an original leveling like this (note that [ ] indicates token boundaries, not sstable size on disk, all sstables are the same size)
L3 [][][][][][][][][][][]
L2 [ ][ ][ ][ ]
L1 [ ][ ]
L0 [ ]
Will look like this after being dropped to L0 and sorted by last token (and, to illustrate overlap, the overlapping ones are put on a new line):
[][][]
[ ][][][]
[ ]
[ ]
