Holen Sie sich einen Cluster

Verwenden Sie das folgende Beispiel, um Informationen über einen Cluster mit einer oder mehreren Regionen zu erhalten.

import boto3
from datetime import datetime
import json


def get_cluster(region, identifier):
    try:
        client = boto3.client("dsql", region_name=region)
        return client.get_cluster(identifier=identifier)
    except:
        print(f"Unable to get cluster {identifier} in region {region}")
        raise


def main():
    region = "us-east-1"
    cluster_id = "<your cluster id>"
    response = get_cluster(region, cluster_id)

    print(json.dumps(response, indent=2, default=lambda obj: obj.isoformat() if isinstance(obj, datetime) else None))


if __name__ == "__main__":
    main()

Verwenden Sie das folgende Beispiel, um Informationen über einen Cluster mit einer oder mehreren Regionen abzurufen.

  const client = new DSQLClient({ region });

  const getClusterCommand = new GetClusterCommand({

  const response = await getCluster(region, clusterId);
  console.log("Cluster: ", response);
}

main();
                

Mit dem folgenden Beispiel können Sie Informationen zu einem Cluster mit einer oder mehreren Regionen abrufen.

package org.example;

public class GetCluster {

    public static void main(String[] args) {
        Region region = Region.US_EAST_1;

        }
    }
}
                

Im folgenden Beispiel können Sie Informationen zu einem Cluster mit einer oder mehreren Regionen abrufen.

async fn dsql_client(region: &'static str) -> Client {
    // Load default SDK configuration
    let sdk_defaults = load_defaults(BehaviorVersion::latest()).await;

    // You can set your own credentials by following this guide
    // https://docs.aws.amazon.com/sdk-for-rust/latest/dg/credproviders.html
    let credentials = sdk_defaults.credentials_provider().unwrap();

    let config = Config::builder()
        .behavior_version(BehaviorVersion::latest())
        .credentials_provider(credentials)
        .region(Region::new(region))

#[tokio::main(flavor = "current_thread")]
pub async fn main() -> anyhow::Result<()> {
    let region = "us-east-1";

    let cluster = get_cluster(region, "<your cluster id>").await;
    println!("{:#?}", cluster);

    Ok(())
}
                

Im folgenden Beispiel können Sie Informationen zu einem Cluster mit einer oder mehreren Regionen abrufen.

require "aws-sdk-dsql"

def get_cluster(region, identifier)
  client = Aws::DSQL::Client.new(region: region)
  client.get_cluster(identifier: identifier)

end

def main
  region = "us-east-1"
  cluster_id = "<your cluster id>"
  cluster = get_cluster(region, cluster_id)
  pp cluster
end
