将 DeleteCluster 与 Amazon SDK 或命令行工具结合使用

删除没有最终集群快照的集群 此示例删除集群，强制删除数据，因此不会创建最终集群快照。命令：

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

删除集群，允许使用最终集群快照 此示例删除集群，但指定最终集群快照。命令：

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

请删除集群。

    public static void deleteRedshiftCluster(RedshiftClient redshiftClient, String clusterId) {
        try {
            DeleteClusterRequest deleteClusterRequest = DeleteClusterRequest.builder()
                .clusterIdentifier(clusterId)
                .skipFinalClusterSnapshot(true)
                .build();

            DeleteClusterResponse response = redshiftClient.deleteCluster(deleteClusterRequest);
            System.out.println("The status is " + response.cluster().clusterStatus());

        } catch (RedshiftException e) {
            System.err.println(e.getMessage());
            System.exit(1);
        }
    }

创建客户端。

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

创建集群。

// 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();

请删除集群。

suspend fun deleteRedshiftCluster(clusterId: String?) {

    val request = DeleteClusterRequest {
        clusterIdentifier = clusterId
        skipFinalClusterSnapshot = true
    }

    RedshiftClient { region = "us-west-2" }.use { redshiftClient ->
        val response = redshiftClient.deleteCluster(request)
        println("The status is ${response.cluster?.clusterStatus}")
    }
}

class RedshiftWrapper:
    """
    Encapsulates Amazon Redshift cluster operations.
    """

    def __init__(self, redshift_client):
        """
        :param redshift_client: A Boto3 Redshift client.
        """
        self.client = redshift_client


    def delete_cluster(self, cluster_identifier):
        """

        :param cluster_identifier: The cluster identifier.
        """
        try:
            self.client.delete_cluster(
                ClusterIdentifier=cluster_identifier, SkipFinalClusterSnapshot=True
            )
        except ClientError as err:
            logging.error(
                "Couldn't delete a cluster. Here's why: %s: %s",
                err.response["Error"]["Code"],
                err.response["Error"]["Message"],
            )

以下代码会实例化 RedshiftWrapper 对象。

    client = boto3.client("redshift")
    redhift_wrapper = RedshiftWrapper(client)
