/**
 * <p>Creates a new item, or replaces an old item with a new item. If an item that has the same primary key as the new item already exists in the specified table, the new item completely replaces the existing item. You can perform a conditional put operation (add a new item if one with the specified primary key doesn't exist), or replace an existing item if it has certain attribute values. You can return the item's attribute values in the same operation, using the <code>ReturnValues</code> parameter.</p>

 *          <p>When you add an item, the primary key attributes are the only required attributes.
 *             Attribute values cannot be null.</p>
 *             <p>Empty String and Binary attribute values are allowed. Attribute values of type String and Binary must have a length greater than zero if the attribute is used as a key attribute for a table or index.
 *             Set type attributes cannot be empty. </p>
 *             <p>Invalid Requests with empty values will
 *             be rejected with a <code>ValidationException</code> exception.</p>
 *          <note>
 *             <p>To prevent a new item from replacing an existing item, use a conditional expression
 *          that contains the <code>attribute_not_exists</code> function with the name of the
 *          attribute being used as the partition key for the table.  Since every record must contain
 *          that attribute, the <code>attribute_not_exists</code> function will only succeed if
 *          no matching item exists.</p>
 *          </note>
