Examples of org.apache.cassandra.thrift.KeyRange

org.apache.cassandra.thrift.KeyRange
The semantics of start keys and tokens are slightly different. Keys are start-inclusive; tokens are start-exclusive. Token ranges may also wrap -- that is, the end token may be less than the start one. Thus, a range from keyX to keyX is a one-element range, but a range from tokenY to tokenY is the full ring.
