| Executor |
| ======== |
| |
| Executors are the mechanism by which task instances get run. |
| |
| Airflow has support for various executors. Current used is determined by the ``executor`` option in the ``[core]`` |
| section of the configuration file. This option should contain the name executor e.g. ``KubernetesExecutor`` |
| if it is a core executor. If it is to load your own executor, then you should specify the |
| full path to the module e.g. ``my_acme_company.executors.MyCustomExecutor``. |
| |
| .. note:: |
| For more information on setting the configuration, see :doc:`../howto/set-config`. |
| |
| If you want to check which executor is currently set, you can use ``airflow config get-value core executor`` command as in |
| the example below. |
| |
| .. code-block:: bash |
| |
| $ airflow config get-value core executor |
