Utilizzare CreateCluster con un SDK AWS o una CLI

Creare un cluster con parametri minimi Questo esempio crea un cluster con il set minimo di parametri. Per impostazione predefinita, l’output è in formato JSON. Comando:

aws redshift create-cluster --node-type dw.hs1.xlarge --number-of-nodes 2 --master-username adminuser --master-user-password TopSecret1 --cluster-identifier mycluster

Risultato:
