Code sample

Java

Before trying this sample, follow the Java setup instructions in the BigQuery quickstart using client libraries. For more information, see the BigQuery Java API reference documentation.

import com.google.api.gax.rpc.ApiException;
import com.google.cloud.bigquery.datatransfer.v1.DataTransferServiceClient;
import com.google.cloud.bigquery.datatransfer.v1.TransferConfig;
import com.google.cloud.bigquery.datatransfer.v1.UpdateTransferConfigRequest;
import com.google.protobuf.FieldMask;
import com.google.protobuf.util.FieldMaskUtil;
import java.io.IOException;

// Sample to update credentials in transfer config.
public class UpdateCredentials {

  public static void main(String[] args) throws IOException {
    // TODO(developer): Replace these variables before running the sample.
    String configId = "MY_CONFIG_ID";
    String serviceAccount = "MY_SERVICE_ACCOUNT";
    TransferConfig transferConfig = TransferConfig.newBuilder().setName(configId).build();
    FieldMask updateMask = FieldMaskUtil.fromString("service_account_name");
    updateCredentials(transferConfig, serviceAccount, updateMask);
  }

  public static void updateCredentials(
      TransferConfig transferConfig, String serviceAccount, FieldMask updateMask)
      throws IOException {
    try (DataTransferServiceClient dataTransferServiceClient = DataTransferServiceClient.create()) {
      UpdateTransferConfigRequest request =
          UpdateTransferConfigRequest.newBuilder()
              .setTransferConfig(transferConfig)
              .setUpdateMask(updateMask)
              .setServiceAccountName(serviceAccount)
              .build();
      dataTransferServiceClient.updateTransferConfig(request);
      System.out.println("Credentials updated successfully");
    } catch (ApiException ex) {
      System.out.print("Credentials was not updated." + ex.toString());
    }
  }
}

Python

Before trying this sample, follow the Python setup instructions in the BigQuery quickstart using client libraries. For more information, see the BigQuery Python API reference documentation.

from google.cloud import bigquery_datatransfer
from google.protobuf import field_mask_pb2

transfer_client = bigquery_datatransfer.DataTransferServiceClient()

service_account_name = "abcdef-test-sa@abcdef-test.iam.gserviceaccount.com"
transfer_config_name = "projects/1234/locations/us/transferConfigs/abcd"

transfer_config = bigquery_datatransfer.TransferConfig(name=transfer_config_name)

transfer_config = transfer_client.update_transfer_config(
    {
        "transfer_config": transfer_config,
        "update_mask": field_mask_pb2.FieldMask(paths=["service_account_name"]),
        "service_account_name": service_account_name,
    }
)

print("Updated config: '{}'".format(transfer_config.name))
