/**
 * <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. </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>
 *          <p>For more information about <code>PutItem</code>, see <a href="https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/WorkingWithItems.html">Working with
 *                 Items</a> in the <i>Amazon DynamoDB Developer Guide</i>.</p>
