| |
| Bases: :class:`airflow.contrib.operators.adls_list_operator.AzureDataLakeStorageListOperator` |
| |
| Synchronizes an Azure Data Lake Storage path with a GCS bucket |
| |
| :param src_adls: The Azure Data Lake path to find the objects (templated) |
| :type src_adls: str |
| :param dest_gcs: The Google Cloud Storage bucket and prefix to |
| store the objects. (templated) |
| :type dest_gcs: str |
| :param replace: If true, replaces same-named files in GCS |
| :type replace: bool |
| :param gzip: Option to compress file for upload |
| :type gzip: bool |
| :param azure_data_lake_conn_id: The connection ID to use when |
| connecting to Azure Data Lake Storage. |
| :type azure_data_lake_conn_id: str |
| :param google_cloud_storage_conn_id: The connection ID to use when |
| connecting to Google Cloud Storage. |
| :type google_cloud_storage_conn_id: str |
| :param delegate_to: The account to impersonate, if any. |
| For this to work, the service account making the request must have |
| domain-wide delegation enabled. |
| :type delegate_to: str |
| |
| **Examples**: |
| The following Operator would copy a single file named |
| ``hello/world.avro`` from ADLS to the GCS bucket ``mybucket``. Its full |
| resulting gcs path will be ``gs://mybucket/hello/world.avro`` :: |
| |
| copy_single_file = AdlsToGoogleCloudStorageOperator( |
| task_id='copy_single_file', |
| src_adls='hello/world.avro', |
| dest_gcs='gs://mybucket', |
| replace=False, |
| azure_data_lake_conn_id='azure_data_lake_default', |
| google_cloud_storage_conn_id='google_cloud_default' |
| ) |
| |
| The following Operator would copy all parquet files from ADLS |
| to the GCS bucket ``mybucket``. :: |
| |
| copy_all_files = AdlsToGoogleCloudStorageOperator( |
| task_id='copy_all_files', |
| src_adls='*.parquet', |
| dest_gcs='gs://mybucket', |
| replace=False, |
| azure_data_lake_conn_id='azure_data_lake_default', |
| google_cloud_storage_conn_id='google_cloud_default' |
| ) |
| |
| The following Operator would copy all parquet files from ADLS |
| path ``/hello/world``to the GCS bucket ``mybucket``. :: |
| |
| copy_world_files = AdlsToGoogleCloudStorageOperator( |
| task_id='copy_world_files', |
| src_adls='hello/world/*.parquet', |
| dest_gcs='gs://mybucket', |
| replace=False, |
| azure_data_lake_conn_id='azure_data_lake_default', |
| google_cloud_storage_conn_id='google_cloud_default' |
