Fichiers de données d'exemple
Rubriques
Les sections suivantes présentent les exemples de fichiers de données utilisés pour charger les tables Forum ProductCatalog, Thread et Reply.
Chaque fichier de données contient plusieurs éléments PutRequest contenant chacun un seul élément. Ces PutRequest éléments sont utilisés comme entrées pour l'BatchWriteItemopération, en utilisant le AWS Command Line Interface (AWS CLI).
