Erstellen eines -Clusters

Verwenden Sie das folgende Beispiel AWS-Region, um einen Cluster in einem einzigen zu erstellen.

import boto3


def create_cluster(region):
    try:
        client = boto3.client("dsql", region_name=region)
        tags = {"Name": "Python single region cluster"}
        cluster = client.create_cluster(tags=tags, deletionProtectionEnabled=True)
        print(f"Initiated creation of cluster: {cluster["identifier"]}")

        print(f"Waiting for {cluster["arn"]} to become ACTIVE")
        client.get_waiter("cluster_active").wait(
            identifier=cluster["identifier"],
            WaiterConfig={
                'Delay': 10,
                'MaxAttempts': 30
            }
        )

        return cluster
    except:
        print("Unable to create cluster")
        raise


def main():
    region = "us-east-1"
    response = create_cluster(region)
    print(f"Created cluster: {response["arn"]}")


if __name__ == "__main__":
    main()
            

Verwenden Sie das folgende Beispiel, um einen Cluster mit mehreren Regionen zu erstellen. Das Erstellen eines Clusters mit mehreren Regionen kann einige Zeit in Anspruch nehmen.

import boto3


def create_multi_region_clusters(region_1, region_2, witness_region):
    try:
        client_1 = boto3.client("dsql", region_name=region_1)
        client_2 = boto3.client("dsql", region_name=region_2)

        # We can only set the witness region for the first cluster
        cluster_1 = client_1.create_cluster(
            deletionProtectionEnabled=True,
            multiRegionProperties={"witnessRegion": witness_region},
            tags={"Name": "Python multi region cluster"}
        )
        print(f"Created {cluster_1["arn"]}")

        # For the second cluster we can set witness region and designate cluster_1 as a peer
        cluster_2 = client_2.create_cluster(
            deletionProtectionEnabled=True,
            multiRegionProperties={"witnessRegion": witness_region, "clusters": [cluster_1["arn"]]},
            tags={"Name": "Python multi region cluster"}
        )

        print(f"Created {cluster_2["arn"]}")
        # Now that we know the cluster_2 arn we can set it as a peer of cluster_1
        client_1.update_cluster(
            identifier=cluster_1["identifier"],
            multiRegionProperties={"witnessRegion": witness_region, "clusters": [cluster_2["arn"]]}
        )
        print(f"Added {cluster_2["arn"]} as a peer of {cluster_1["arn"]}")

        # Now that multiRegionProperties is fully defined for both clusters
        # they'll begin the transition to ACTIVE
        print(f"Waiting for {cluster_1["arn"]} to become ACTIVE")
        client_1.get_waiter("cluster_active").wait(
            identifier=cluster_1["identifier"],
            WaiterConfig={
                'Delay': 10,
                'MaxAttempts': 30
            }
        )

        print(f"Waiting for {cluster_2["arn"]} to become ACTIVE")
        client_2.get_waiter("cluster_active").wait(
            identifier=cluster_2["identifier"],
            WaiterConfig={
                'Delay': 10,
                'MaxAttempts': 30
            }
        )

        return (cluster_1, cluster_2)

    except:
        print("Unable to create cluster")
        raise


def main():
    region_1 = "us-east-1"
    region_2 = "us-east-2"
    witness_region = "us-west-2"
    (cluster_1, cluster_2) = create_multi_region_clusters(region_1, region_2, witness_region)
    print("Created multi region clusters:")
    print("Cluster id: " + cluster_1['arn'])
    print("Cluster id: " + cluster_2['arn'])
