+DatabricksJobsCreateOperator
+============================
+
+Use the
:class:`~airflow.providers.databricks.operators.DatabricksJobsCreateOperator`
to create
+(or reset) a Databricks job. This operator relies on past XComs to remember
the ``job_id`` that
+was created so that repeated calls with this operator will update the existing
job rather than
+creating new ones. When paired with the DatabricksRunNowOperator all runs will
fall under the same
+job within the Databricks UI.
+
+
+Using the Operator
+------------------
+
+There are three 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/create`` endpoint and pass it directly to our
``DatabricksJobsCreateOperator`` through the
+``json`` parameter. With this approach you get full control over the
underlying payload to Jobs REST API, including
+execution of Databricks jobs with multiple tasks, but it's harder to detect
errors because of the lack of the type checking.
+
+The second way to accomplish the same thing is to use the named parameters of
the ``DatabricksJobsCreateOperator`` directly. Note that there is exactly
+one named parameter for each top level parameter in the
``api/2.1/jobs/create`` endpoint.
+
+The third way is to use both the json parameter **AND** the named parameters.
They will be merged
+together. If there are conflicts during the merge, the named parameters will
take precedence and
+override the top level ``json`` keys.
+
+Currently the named parameters that ``DatabricksJobsCreateOperator`` supports
are:
+ - ``name``
+ - ``tags``
+ - ``tasks``
+ - ``job_clusters``
+ - ``email_notifications``
+ - ``webhook_notifications``
+ - ``timeout_seconds``
+ - ``schedule``
+ - ``max_concurrent_runs``
+ - ``git_source``
+ - ``access_control_list``
