/**
 * <p>
 *             <code>TransactGetItems</code> is a synchronous operation that atomically retrieves
 *             multiple items from one or more tables (but not from indexes) in a single account and
 *             Region. A <code>TransactGetItems</code> call can contain up to 25
 *                 <code>TransactGetItem</code> objects, each of which contains a <code>Get</code>
 *             structure that specifies an item to retrieve from a table in the account and Region. A
 *             call to <code>TransactGetItems</code> cannot retrieve items from tables in more than one
 *             AWS account or Region. The aggregate size of the items in the transaction cannot exceed
 *             4 MB.</p>
 *          <p>DynamoDB rejects the entire <code>TransactGetItems</code> request if any of the following is true:</p>
 *          <ul>
 *             <li>
 *                <p>A conflicting operation is in the process of updating an
 *           item to be read.</p>
 *             </li>
 *             <li>
 *                <p>There is insufficient provisioned capacity for the transaction
 *           to be completed.</p>
 *             </li>
 *             <li>
 *                <p>There is a user error, such as an invalid data format.</p>
 *             </li>
 *             <li>
 *                <p>The aggregate size of the items in the transaction cannot exceed 4 MB.</p>
