 * be empty, must have the same name as the global table, must have the same key
 * schema, and must have DynamoDB Streams enabled and must have same provisioned
 * and maximum write capacity units.

 * <note>

 * Although you can use <code>UpdateGlobalTable</code> to add replicas and
 * remove replicas in a single request, for simplicity we recommend that you
 * issue separate requests for adding or removing replicas.
