/**
 * <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>
 * <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>
 * <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>
