/**
 * <p>Creates a global table from an existing table. A global table creates a replication
 *             relationship between two or more DynamoDB tables with the same table name in the
 *             provided Regions. </p>
 *          <note>
 *             <p>This operation only applies to <a href="https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/globaltables.V1.html">Version 2017.11.29</a> of global tables.</p>
 *          </note>
 *
 *          <p>If you want to add a new replica table to a global table, each of the following conditions
 *    must be true:</p>
 *          <ul>
 *             <li>
 *                <p>The table must have the same primary key as all of the other replicas.</p>
 *             </li>
 *             <li>
 *                <p>The table must have the same name as all of the other replicas.</p>
 *             </li>
 *             <li>
 *                <p>The table must have DynamoDB Streams enabled, with the stream containing both the new and the old
 *      images of the item.</p>
 *             </li>
 *             <li>
 *                <p>None of the replica tables in the global table can contain any data.</p>
 *             </li>
 *          </ul>
 *          <p>
 *      If global secondary indexes are specified, then the following conditions must also be met:
 *    </p>
 *         <ul>
 *             <li>
 *                <p>
 *                The global secondary indexes must have the same name.
 *             </p>
 *             </li>
 *             <li>
 *                <p>
 *                The global secondary indexes must have the same hash key and sort key (if present).
 *             </p>
 *             </li>
 *          </ul>
 *          <p>
 *      If local secondary indexes are specified, then the following conditions must also be met:
 *    </p>
 *         <ul>
 *             <li>
 *                <p>
 *                The local secondary indexes must have the same name.
 *             </p>
 *             </li>
 *             <li>
 *                <p>
 *                The local secondary indexes must have the same hash key and sort key (if present).
 *             </p>
 *             </li>
 *          </ul>
 *
 *          <important>
 *             <p>
 *        Write capacity settings should be set consistently across your replica tables and
 *        secondary indexes. DynamoDB strongly recommends enabling auto scaling to manage the write
 *        capacity settings for all of your global tables replicas and indexes.
 *     </p>
 *             <p>
 *        If you prefer to manage write capacity settings manually, you should provision equal
 *        replicated write capacity units to your replica tables. You should also provision
 *        equal replicated write capacity units to matching secondary indexes across
 *        your global table.
 *     </p>
 *          </important>
