Hook for Google DataFusion.

wait_for_operation(self, operation)[source]¶

Waits for long-lasting operation to complete.

wait_for_pipeline_state(self, pipeline_name, pipeline_id, instance_url, namespace='default', success_states=None, failure_states=None, timeout=5 * 60)[source]¶

Polls pipeline state and raises an exception if the state is one of failure_states or the operation timed_out.

get_conn(self)[source]¶

Retrieves connection to DataFusion.

restart_instance(self, instance_name, location, project_id)[source]¶

Restart a single Data Fusion instance. At the end of an operation instance is fully restarted.

Parameters

instance_name (str) -- The name of the instance to restart.
location (str) -- The Cloud Data Fusion location in which to handle the request.
project_id (str) -- The ID of the Google Cloud project that the instance belongs to.

delete_instance(self, instance_name, location, project_id)[source]¶

Deletes a single Date Fusion instance.

Parameters

instance_name (str) -- The name of the instance to delete.
location (str) -- The Cloud Data Fusion location in which to handle the request.
project_id (str) -- The ID of the Google Cloud project that the instance belongs to.

create_instance(self, instance_name, instance, location, project_id=PROVIDE_PROJECT_ID)[source]¶

Creates a new Data Fusion instance in the specified project and location.

Parameters

instance_name (str) -- The name of the instance to create.
instance (Dict[str, Any]) -- An instance of Instance. https://cloud.google.com/data-fusion/docs/reference/rest/v1beta1/projects.locations.instances#Instance
location (str) -- The Cloud Data Fusion location in which to handle the request.
project_id (str) -- The ID of the Google Cloud project that the instance belongs to.

get_instance(self, instance_name, location, project_id)[source]¶

Gets details of a single Data Fusion instance.

Parameters

instance_name (str) -- The name of the instance.
location (str) -- The Cloud Data Fusion location in which to handle the request.
project_id (str) -- The ID of the Google Cloud project that the instance belongs to.

patch_instance(self, instance_name, instance, update_mask, location, project_id=PROVIDE_PROJECT_ID)[source]¶

Updates a single Data Fusion instance.

Parameters

instance_name (str) -- The name of the instance to create.
instance (Dict[str, Any]) -- An instance of Instance. https://cloud.google.com/data-fusion/docs/reference/rest/v1beta1/projects.locations.instances#Instance
update_mask (str) -- Field mask is used to specify the fields that the update will overwrite in an instance resource. The fields specified in the updateMask are relative to the resource, not the full request. A field will be overwritten if it is in the mask. If the user does not provide a mask, all the supported fields (labels and options currently) will be overwritten. A comma-separated list of fully qualified names of fields. Example: "user.displayName,photo". https://developers.google.com/protocol-buffers/docs/reference/google.protobuf?_ga=2.205612571.-968688242.1573564810#google.protobuf.FieldMask
location (str) -- The Cloud Data Fusion location in which to handle the request.
project_id (str) -- The ID of the Google Cloud project that the instance belongs to.

create_pipeline(self, pipeline_name, pipeline, instance_url, namespace='default')[source]¶

Creates a Cloud Data Fusion pipeline.

Parameters

pipeline_name (str) -- Your pipeline name.
pipeline (Dict[str, Any]) -- The pipeline definition. For more information check: https://docs.cdap.io/cdap/current/en/developer-manual/pipelines/developing-pipelines.html#pipeline-configuration-file-format
instance_url (str) -- Endpoint on which the REST APIs is accessible for the instance.
namespace (str) -- if your pipeline belongs to a Basic edition instance, the namespace ID is always default. If your pipeline belongs to an Enterprise edition instance, you can create a namespace.

delete_pipeline(self, pipeline_name, instance_url, version_id=None, namespace='default')[source]¶

Deletes a Cloud Data Fusion pipeline.

Parameters

pipeline_name (str) -- Your pipeline name.
version_id (Optional[str]) -- Version of pipeline to delete
instance_url (str) -- Endpoint on which the REST APIs is accessible for the instance.
namespace (str) -- f your pipeline belongs to a Basic edition instance, the namespace ID is always default. If your pipeline belongs to an Enterprise edition instance, you can create a namespace.

list_pipelines(self, instance_url, artifact_name=None, artifact_version=None, namespace='default')[source]¶

Lists Cloud Data Fusion pipelines.

Parameters

artifact_version (Optional[str]) -- Artifact version to filter instances
artifact_name (Optional[str]) -- Artifact name to filter instances
instance_url (str) -- Endpoint on which the REST APIs is accessible for the instance.
namespace (str) -- f your pipeline belongs to a Basic edition instance, the namespace ID is always default. If your pipeline belongs to an Enterprise edition instance, you can create a namespace.
