class airflow.providers.google.cloud.operators.cloud_storage_transfer_service.TransferJobPreprocessor(body, aws_conn_id='aws_default', default_schedule=False)[source]¶

Helper class for preprocess of transfer job body.

process_body()[source]¶

Injects AWS credentials into body if needed and reformats schedule information.

Returns: Preprocessed body
Return type: dict

class airflow.providers.google.cloud.operators.cloud_storage_transfer_service.TransferJobValidator(body)[source]¶

Helper class for validating transfer job body.

validate_body()[source]¶

Validate the body.

Checks if body specifies transferSpec if yes, then check if AWS credentials are passed correctly and no more than 1 data source was selected.

Raises: AirflowException

class airflow.providers.google.cloud.operators.cloud_storage_transfer_service.CloudDataTransferServiceCreateJobOperator(*, body, aws_conn_id='aws_default', gcp_conn_id='google_cloud_default', api_version='v1', project_id=None, google_impersonation_chain=None, **kwargs)[source]¶

Bases: airflow.providers.google.cloud.operators.cloud_base.GoogleCloudBaseOperator

Creates a transfer job that runs periodically.

Warning

This operator is NOT idempotent in the following cases:

name is not passed in body param
transfer job name has been soft deleted. In this case, each new task will receive a unique suffix

If you run it many times, many transfer jobs will be created in the Google Cloud.

Parameters

body (dict) –
(Required) The request body, as described in https://cloud.google.com/storage-transfer/docs/reference/rest/v1/transferJobs#TransferJob With three additional improvements:
- dates can be given in the form datetime.date
- times can be given in the form datetime.time
- credentials to Amazon Web Service should be stored in the connection and indicated by the aws_conn_id parameter
aws_conn_id (str | None) – The connection ID used to retrieve credentials to Amazon Web Service.
gcp_conn_id (str) – The connection ID used to connect to Google Cloud.
