DatabricksSubmitRunOperator
===========================

Use the :class:`~airflow.providers.databricks.operators.DatabricksSubmitRunOperator` to submit
a new Databricks job via Databricks `api/2.1/jobs/runs/submit <https://docs.databricks.com/dev-tools/api/latest/jobs.html#operation/JobsRunsSubmit>`_ API endpoint.


Using the Operator
------------------

There are two ways to instantiate this operator. In the first way, you can take the JSON payload that you typically use
to call the ``api/2.1/jobs/runs/submit`` endpoint and pass it directly to our ``DatabricksSubmitRunOperator`` through the ``json`` parameter.

Another way to accomplish the same thing is to use the named parameters of the ``DatabricksSubmitRunOperator`` directly. Note that there is exactly
one named parameter for each top level parameter in the ``runs/submit`` endpoint.

Examples
--------

Specifying parameters as JSON
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

An example usage of the DatabricksSubmitRunOperator is as follows:

.. exampleinclude:: /../../airflow/providers/databricks/example_dags/example_databricks.py
    :language: python
    :start-after: [START howto_operator_databricks_json]
    :end-before: [END howto_operator_databricks_json]

Using named parameters
^^^^^^^^^^^^^^^^^^^^^^

You can also use named parameters to initialize the operator and run the job.

.. exampleinclude:: /../../airflow/providers/databricks/example_dags/example_databricks.py
    :language: python
    :start-after: [START howto_operator_databricks_named]
    :end-before: [END howto_operator_databricks_named]
