Elimina il cluster in Aurora DSQL con AWS SDKs

Per eliminare un cluster in un unico cluster Regione AWS, usa il seguente esempio.

import boto3

def delete_cluster(cluster_id, client):
    try: 
        return client.delete_cluster(identifier=cluster_id)
    except:
        print("Unable to delete cluster " + cluster_id)
        raise

def main():
    region = "us-east-1"
    client = boto3.client("dsql", region_name=region)
    cluster_id = "foo0bar1baz2quux3quuux4"
    response = delete_cluster(cluster_id, client)
    print("Deleting cluster with ID: " + cluster_id +  ", Cluster Status: " + response['status'])

if __name__ == "__main__":
    main()
                

Per eliminare un cluster multiregionale, utilizzare l'esempio seguente.

import boto3

def delete_multi_region_clusters(linkedClusterArns, client):
    client.delete_multi_region_clusters(linkedClusterArns=linkedClusterArns)

def main():
    region = "us-east-1"
    client = boto3.client("dsql", region_name=region)
    linkedClusterArns = [
        "arn:aws:dsql:us-east-1:111111999999::cluster/foo0bar1baz2quux3quuux4",
        "arn:aws:dsql:us-east-2:111111999999::cluster/bar0foo1baz2quux3quuux4"
    ]
    delete_multi_region_clusters(linkedClusterArns, client)
    print("Deleting clusters with ARNs:", linkedClusterArns)

if __name__ == "__main__":
    main()
                

L'esempio seguente consente di eliminare un cluster in un singolo Regione AWS.

#include <aws/core/Aws.h>
#include <aws/dsql/DSQLClient.h>
#include <aws/dsql/model/DeleteClusterRequest.h>
#include <iostream>

using namespace Aws;
using namespace Aws::DSQL;
using namespace Aws::DSQL::Model;

ClusterStatus deleteCluster(const String& clusterId, DSQLClient& client) {
    DeleteClusterRequest request;
    request.SetIdentifier(clusterId);

    DeleteClusterOutcome outcome = client.DeleteCluster(request);
    ClusterStatus status = ClusterStatus::NOT_SET;

    if (outcome.IsSuccess()) {
        const auto& cluster = outcome.GetResult();
        status = cluster.GetStatus();
    } else {
        std::cerr << "Delete operation failed: " << outcome.GetError().GetMessage() << std::endl;
    }
    std::cout << "Cluster Status: " << ClusterStatusMapper::GetNameForClusterStatus(status) << std::endl;
    return status;
}

int main() {
    Aws::SDKOptions options;
    Aws::InitAPI(options);
    DSQLClientConfiguration clientConfig;

    clientConfig.region = "us-east-1";

    DSQLClient client(clientConfig);
    String clusterId = "foo0bar1baz2quux3quuux4";

    deleteCluster(clusterId, client);
    Aws::ShutdownAPI(options);
    return 0;
}
                

Per eliminare un cluster multiregionale, utilizzare l'esempio seguente. L'eliminazione di un cluster multiregionale potrebbe richiedere del tempo.

#include <aws/core/Aws.h>

    request.SetLinkedClusterArns(linkedClusterArns);

    DeleteMultiRegionClustersOutcome outcome = client.DeleteMultiRegionClusters(request);

    if (outcome.IsSuccess()) {
        std::cout << "Successfully deleted clusters." << std::endl;
        return linkedClusterArns;
    } else {
        std::cerr << "Delete operation failed: " << outcome.GetError().GetMessage() << std::endl;
        return {};
    }
}

int main() {
    Aws::SDKOptions options;
    Aws::InitAPI(options);
    DSQLClientConfiguration clientConfig;

    clientConfig.region = "us-east-1";

    DSQLClient client(clientConfig);

    std::vector<Aws::String> linkedClusterArns = {
        "arn:aws:dsql:us-east-1:111111999999::cluster/foo0bar1baz2quux3quuux4",
        "arn:aws:dsql:us-east-2:111111999999::cluster/bar0foo1baz2quux3quuux4"
    };

    std::vector<Aws::String> deletedArns = deleteMultiRegionClusters(linkedClusterArns, client);

    if (!deletedArns.empty()) {
        std::cout << "Deleted Cluster ARNs: " << std::endl;
        for (const auto& arn : deletedArns) {
            std::cout << arn << std::endl;
        }
    }

    Aws::ShutdownAPI(options);
    return 0;
}
