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 | None) – The ID of the Google Cloud project that the instance belongs to.

Parameters

  • pipeline_name (str) – Your pipeline name.

  • instance_name (str) – The name of the instance.

  • success_states (list[str] | None) – If provided the operator will wait for pipeline to be in one of the provided states.

  • pipeline_timeout (int) – How long (in seconds) operator should wait for the pipeline to be in one of success_states. Works only if success_states are provided.

  • location (str) – The Cloud Data Fusion location in which to handle the request.

  • runtime_args (dict[str, Any] | None) – Optional runtime args to be passed to the pipeline

  • 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.

  • api_version (str) – The version of the api that will be requested for example ‘v3’.

  • gcp_conn_id (str) – The connection ID to use when fetching connection info.

  • asynchronous – Flag to return after submitting the pipeline ID to the Data Fusion API. This is useful for submitting long-running pipelines and waiting on them asynchronously using the CloudDataFusionPipelineStateSensor

  • deferrable – Run operator in the deferrable mode. Is not related to asynchronous parameter. While asynchronous parameter gives a possibility to wait until pipeline reaches terminate state using sleep() method, deferrable mode checks for the state using asynchronous calls. It is not possible to use both asynchronous and deferrable parameters at the same time.

  • poll_interval – Polling period in seconds to check for the status. Used only in deferrable mode.
