| |
| .. py:class:: SequentialExecutor |
| |
| Bases: :py:obj:`airflow.executors.base_executor.BaseExecutor` |
| |
| This executor will only run one task instance at a time, can be used |
| for debugging. It is also the only executor that can be used with sqlite |
| since sqlite doesn't support multiple connections. |
| |
| Since we want airflow to work out of the box, it defaults to this |
| SequentialExecutor alongside sqlite as you first install it. |
| |
| .. py:method:: execute_async(self, key, command, queue = None, executor_config = None) |
| |
| This method will execute the command asynchronously. |
| |
| :param key: Unique key for the task instance |
| :param command: Command to run |
| :param queue: name of the queue |
| :param executor_config: Configuration passed to the executor. |
| |
| |
| .. py:method:: sync(self) |
| |
| Sync will get called periodically by the heartbeat method. |
| Executors should override this to perform gather statuses. |
| |
| |
| .. py:method:: end(self) |
| |
| End the executor. |
| |
| |
| .. py:method:: terminate(self) |
| |
| Terminate the executor is not doing anything. |
