Class DataTransferServiceClient (2.0.0)

DataTransferServiceClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.bigquery.datatransfer_v1.services.data_transfer_service.transports.base.DataTransferServiceTransport] = None, client_options: <module 'google.api_core.client_options' from '/workspace/python-bigquery-datatransfer/.nox/docfx/lib/python3.9/site-packages/google/api_core/client_options.py'> = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

The Google BigQuery Data Transfer Service API enables BigQuery users to configure the transfer of their data from other Google Products into BigQuery. This service contains methods that are end user exposed. It backs up the frontend.

Methods

DataTransferServiceClient

DataTransferServiceClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.bigquery.datatransfer_v1.services.data_transfer_service.transports.base.DataTransferServiceTransport] = None, client_options: <module 'google.api_core.client_options' from '/workspace/python-bigquery-datatransfer/.nox/docfx/lib/python3.9/site-packages/google/api_core/client_options.py'> = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Instantiate the data transfer service client.

Parameters

Name	Description
`credentials`	`Optional[google.auth.credentials.Credentials]` The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.
`transport`	`Union[str, .DataTransferServiceTransport]` The transport to use. If set to None, a transport is chosen automatically.
`client_options`	`ClientOptions` Custom options for the client. It won't take effect if a `transport` instance is provided. (1) The `api_endpoint` property can be used to override the default endpoint provided by the client. GOOGLE_API_USE_MTLS_ENDPOINT environment variable can also be used to override the endpoint: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint) and "auto" (auto switch to the default mTLS endpoint if client certificate is present, this is the default value). However, the `api_endpoint` property takes precedence if provided. (2) If GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the `client_cert_source` property can be used to provide client certificate for mutual TLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not set, no client certificate will be used.
`client_info`	`google.api_core.gapic_v1.client_info.ClientInfo` The client info used to send a user-agent string along with API requests. If `None`, then default info will be used. Generally, you only need to set this if you're developing your own client library.

Exceptions

Type	Description
`google.auth.exceptions.MutualTLSChannelError`	If mutual TLS transport creation failed for any reason.

check_valid_creds

check_valid_creds(request: Optional[google.cloud.bigquery.datatransfer_v1.types.datatransfer.CheckValidCredsRequest] = None, *, name: Optional[str] = None, retry: google.api_core.retry.Retry = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())

Returns true if valid credentials exist for the given data source and requesting user. Some data sources doesn't support service account, so we need to talk to them on behalf of the end user. This API just checks whether we have OAuth token for the particular user, which is a pre-requisite before user can create a transfer config.

Parameters

Name	Description
`request`	`.datatransfer.CheckValidCredsRequest` The request object. A request to determine whether the user has valid credentials. This method is used to limit the number of OAuth popups in the user interface. The user id is inferred from the API call context. If the data source has the Google+ authorization type, this method returns false, as it cannot be determined whether the credentials are already valid merely based on the user id.
`name`	`str` Required. The data source in the form: `projects/{project_id}/dataSources/{data_source_id}` or `projects/{project_id}/locations/{location_id}/dataSources/{data_source_id}`. This corresponds to the `name` field on the `request` instance; if `request` is provided, this should not be set.
`retry`	`google.api_core.retry.Retry` Designation of what errors, if any, should be retried.
`timeout`	`float` The timeout for this request.
`metadata`	`Sequence[Tuple[str, str]]` Strings which should be sent along with the request as metadata.

Returns

Type	Description
`.datatransfer.CheckValidCredsResponse`	A response indicating whether the credentials exist and are valid.
