findShortestSeparator

byte[] findShortestSeparator(byte[] start,
                           byte[] limit)

If start < limit, returns a short key in [start,limit). Simple comparator implementations should return start unchanged,

findShortSuccessor

byte[] findShortSuccessor(byte[] key)

returns a 'short key' where the 'short key' >= key. Simple comparator implementations should return key unchanged,
