Utilizzare DeleteCluster con un SDK AWS o una CLI

Eliminare un cluster senza snapshot finale Questo esempio elimina un cluster, forzando l’eliminazione dei dati in modo da impedire la creazione di uno snapshot finale del cluster. Comando:

aws redshift delete-cluster --cluster-identifier mycluster --skip-final-cluster-snapshot

Eliminare un cluster con snapshot finale L’esempio seguente elimina un cluster, ma specifica la creazione di uno snapshot finale del cluster. Comando:

aws redshift delete-cluster --cluster-identifier mycluster --final-cluster-snapshot-identifier myfinalsnapshot

Crea il client.

import { RedshiftClient } from "@aws-sdk/client-redshift";
// Set the AWS Region.
const REGION = "REGION";
//Set the Redshift Service Object
const redshiftClient = new RedshiftClient({ region: REGION });
export { redshiftClient };

Crea il cluster .

// Import required AWS SDK clients and commands for Node.js
import { DeleteClusterCommand } from "@aws-sdk/client-redshift";
import { redshiftClient } from "./libs/redshiftClient.js";

const params = {
  ClusterIdentifier: "CLUSTER_NAME",
  SkipFinalClusterSnapshot: false,
  FinalClusterSnapshotIdentifier: "CLUSTER_SNAPSHOT_ID",
};

const run = async () => {
  try {
    const data = await redshiftClient.send(new DeleteClusterCommand(params));
    console.log("Success, cluster deleted. ", data);
    return data; // For unit tests.
  } catch (err) {
    console.log("Error", err);
  }
};
run();
