| Sequential Executor |
| =================== |
| |
| The :class:`~airflow.executors.sequential_executor.SequentialExecutor` is the default executor when you first install ``airflow``. |
| It is the only executor that can be used with ``sqlite`` since ``sqlite`` doesn't support multiple connections. |
| This executor will only run one task instance at a time. For production use case, please use other executors. |
