Vous pouvez ajuster les valeurs de débit à chaud lorsque vous créez votre table DynamoDB en suivant les étapes ci-dessous. Ces étapes s'appliquent également lors de la création d'une table globale ou d'un index secondaire.
Pour créer une table DynamoDB et ajuster les valeurs du débit de chaleur via la console, procédez comme suit :
Connectez-vous à la console DynamoDB AWS Management Console et ouvrez-la à l'adresse. https://console.aws.amazon.com/dynamodb/
-
Sélectionnez Créer une table.
-
Choisissez un nom de table, une clé de partition et une clé de tri (facultatif).
-
Pour les paramètres du tableau, choisissez Personnaliser les paramètres.
-
Dans le champ Débit à chaud, sélectionnez Augmenter le débit à chaud.
-
Ajustez les unités de lecture par seconde et les unités d'écriture par seconde. Ces deux paramètres définissent le débit maximal que votre table peut gérer instantanément.
-
Continuez à ajouter les autres détails du tableau, puis sélectionnez Créer un tableau.
