Executes a data factory pipeline.
.. seealso::
For more information on how to use this operator, take a look at the guide:
:ref:`howto/operator:AzureDataFactoryRunPipelineOperator`
:param azure_data_factory_conn_id: The connection identifier for connecting to Azure Data Factory.
:param pipeline_name: The name of the pipeline to execute.
:param wait_for_termination: Flag to wait on a pipeline run's termination. By default, this feature is
enabled but could be disabled to perform an asynchronous wait for a long-running pipeline execution
using the ``AzureDataFactoryPipelineRunSensor``.
:param resource_group_name: The resource group name. If a value is not passed in to the operator, the
``AzureDataFactoryHook`` will attempt to use the resource group name provided in the corresponding
connection.
:param factory_name: The data factory name. If a value is not passed in to the operator, the
``AzureDataFactoryHook`` will attempt to use the factory name name provided in the corresponding
connection.
:param reference_pipeline_run_id: The pipeline run identifier. If this run ID is specified the parameters
of the specified run will be used to create a new run.
:param is_recovery: Recovery mode flag. If recovery mode is set to `True`, the specified referenced
pipeline run and the new run will be grouped under the same ``groupId``.
:param start_activity_name: In recovery mode, the rerun will start from this activity. If not specified,
all activities will run.
:param start_from_failure: In recovery mode, if set to true, the rerun will start from failed activities.
The property will be used only if ``start_activity_name`` is not specified.
:param parameters: Parameters of the pipeline run. These parameters are referenced in a pipeline via
``@pipeline().parameters.parameterName`` and will be used only if the ``reference_pipeline_run_id`` is
not specified.
:param timeout: Time in seconds to wait for a pipeline to reach a terminal status for non-asynchronous
waits. Used only if ``wait_for_termination`` is True.
:param check_interval: Time in seconds to check on a pipeline run's status for non-asynchronous waits.
Used only if ``wait_for_termination`` is True.
