Examples of KeyRange

com.fasterxml.clustermate.api.KeyRange
Logical slice of a {@link KeySpace}; a consecutive range of individual key values within value space, defined by two parameters: starting key value (inclusive), and length between 0 and length of {@link KeySpace}.
Instances have natural ordering based on {@link #getStart()}, ascending.
com.google.appengine.api.datastore.KeyRange
com.salesforce.phoenix.query.KeyRange
Class that represents an upper/lower bound key range. @author jtaylor @since 0.1
com.sleepycat.util.keyrange.KeyRange
Encapsulates a key range for use with a RangeCursor.

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.
