DatabricksRunNowOperator
========================

Use the :class:`~airflow.providers.databricks.operators.DatabricksRunNowOperator` to trigger a run of an existing Databricks job
via `api/2.1/jobs/run-now <https://docs.databricks.com/dev-tools/api/latest/jobs.html#operation/JobsRunNow>`_ 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/run-now`` endpoint and pass it directly to our ``DatabricksRunNowOperator`` through the ``json`` parameter.

Another way to accomplish the same thing is to use the named parameters of the ``DatabricksRunNowOperator`` directly.
Note that there is exactly one named parameter for each top level parameter in the ``jobs/run-now`` endpoint.

The only required parameters are either:

* ``job_id`` - to specify ID of the existing Databricks job
* ``job_name`` - Name of the existing Databricks job. It will throw exception if job isn't found, of if there are multiple jobs with the same name.

All other parameters are optional and described in documentation for ``DatabricksRunNowOperator``.  For example, you can pass additional parameters to a job using one of the following parameters, depending on the type of tasks in the job:

* ``notebook_params``
* ``python_params``
* ``python_named_parameters``
* ``jar_params``
* ``spark_submit_params``

DatabricksRunNowDeferrableOperator
==================================

Deferrable version of the :class:`~airflow.providers.databricks.operators.DatabricksRunNowOperator` operator.

It allows to utilize Airflow workers more effectively using `new functionality introduced in Airflow 2.2.0 <https://airflow.apache.org/docs/apache-airflow/2.2.0/concepts/deferring.html#triggering-deferral>`_
