KeySchema class

The KeySchema identifies the primary key as a one attribute primary key (hash) or a composite two attribute (hash-and-range) primary key. Single attribute primary keys have one index value: a HashKeyElement. A composite hash-and-range primary key contains two attribute values: a HashKeyElement and a RangeKeyElement.
