The ``RenderConfig`` class takes the following arguments:

- ``emit_datasets``: whether or not to emit Airflow datasets to be used for data-aware scheduling. Defaults to True. Depends on `additional dependencies <lineage.html>`_. If a model in the project has a name containing multibyte characters, the dataset name will be URL-encoded.
- ``emit_datasets``: whether or not to emit Airflow datasets to be used for data-aware scheduling. Defaults to True. This feature is only available for ``ExecutionMode.LOCAL``, ``ExecutionMode.VIRTUALENV`` and ``ExecutionMode.WATCHER``.
- ``test_behavior``: how to run tests. Defaults to running a model's tests immediately after the model is run. For more information, see the `Testing Behavior <testing-behavior.html>`_ section.
- ``load_method``: how to load your dbt project. See `Parsing Methods <parsing-methods.html>`_ for more information.
- ``invocation_mode``: (new in v1.9) how to run ``dbt ls``, when using ``LoadMode.DBT_LS``. Learn more about this below.

By default, if using a version between Airflow 2.4 or higher is used, Cosmos emits `Airflow Datasets <https://airflow.apache.org/docs/apache-airflow/stable/concepts/datasets.html>`_ when running dbt projects. This allows you to use Airflow's data-aware scheduling capabilities to schedule your dbt projects. Cosmos emits datasets using the OpenLineage URI format, as detailed in the `OpenLineage Naming Convention <https://github.com/OpenLineage/OpenLineage/blob/main/spec/Naming.md>`_.

.. important::

This feature is only available for ``ExecutionMode.LOCAL``, ``ExecutionMode.VIRTUALENV`` and ``ExecutionMode.WATCHER``.

Cosmos calculates these URIs during the task execution, by using the library `OpenLineage Integration Common <https://pypi.org/project/openlineage-integration-common/>`_.
