Ejemplos de archivos de datos
Temas
En las secciones siguientes se muestran los ejemplos de archivos de datos que se utilizan para cargar las tablas ProductCatalog, Forum, Thread y Reply.
Cada archivo de datos contiene varios componentes PutRequest, cada uno de los cuales contienen un único elemento. Estos componentes PutRequest se utilizan como datos de entrada de la operación BatchWriteItem, mediante la AWS Command Line Interface (AWS CLI).
