如何在DynamoDB中以编程方式恢复备份表？(使用C#)

var credentials = new Amazon.Runtime.BasicAWSCredentials("AccessKey", "SecretKey");
var config = new AmazonDynamoDBConfig { RegionEndpoint = Amazon.RegionEndpoint.YourRegion };
var client = new AmazonDynamoDBClient(credentials, config);

var request = new RestoreTableFromBackupRequest
{
    BackupArn = "arn:aws:dynamodb:your-region:your-account-id:backup/your-backup-arn",
    TargetTableName = "your-table-name"
};

var response = await client.RestoreTableFromBackupAsync(request);

var describeRequest = new DescribeTableRequest { TableName = "your-table-name" };

DescribeTableResponse describeResponse;
do
{
    describeResponse = await client.DescribeTableAsync(describeRequest);
    var tableStatus = describeResponse.Table.TableStatus;
    Console.WriteLine($"Table status: {tableStatus}");
    await Task.Delay(TimeSpan.FromSeconds(5)); // 等待5秒后再次轮询
} while (describeResponse.Table.TableStatus != "ACTIVE");
