Dapatkan cluster

Untuk mendapatkan informasi tentang cluster tunggal atau Multi-region, gunakan contoh berikut.

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()

Untuk mendapatkan informasi tentang cluster tunggal atau Multi-region, gunakan contoh berikut.

import { DSQLClient, GetClusterCommand } from "@aws-sdk/client-dsql";

async function getCluster(region, clusterId) {

  const client = new DSQLClient({ region });

  const getClusterCommand = new GetClusterCommand({
    identifier: clusterId,
  });

  try {
    return await client.send(getClusterCommand);
  } catch (error) {
    if (error.name === "ResourceNotFoundException") {
      console.log("Cluster ID not found or deleted");
    }
    throw error;
  }
}

async function main() {
  const region = "us-east-1";
  const clusterId = "<CLUSTER_ID>";

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

main();
