Bases:
airflow.providers.microsoft.azure.operators.adls.ADLSListOperator
Synchronizes an Azure Data Lake Storage path with a GCS bucket.
- Parameters
src_adls (str) – The Azure Data Lake path to find the objects (templated)
dest_gcs (str) – The Google Cloud Storage bucket and prefix to store the objects. (templated)
replace (bool) – If true, replaces same-named files in GCS
gzip (bool) – Option to compress file for upload
azure_data_lake_conn_id (str) – The connection ID to use when connecting to Azure Data Lake Storage.
gcp_conn_id (str) – (Optional) The connection ID used to connect to Google Cloud.
google_impersonation_chain (str | Sequence[str] | None) – Optional Google service account to impersonate using short-term credentials, or chained list of accounts required to get the access_token of the last account in the list, which will be impersonated in the request. If set as a string, the account must grant the originating account the Service Account Token Creator IAM role. If set as a sequence, the identities from the list must grant Service Account Token Creator IAM role to the directly preceding identity, with first account from the list granting this role to the originating account (templated).
- Examples:
The following Operator would copy a single file named
hello/world.avro
from ADLS to the GCS bucketmybucket
. Its full resulting gcs path will begs://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", gcp_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', gcp_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', gcp_conn_id='google_cloud_default' )
