气流跳过当前任务 [英] Airflow skip current task

问题描述

Airflow是否可以从（Python）Operator中跳过当前任务？例如：

Is there a way for Airflow to skip current task from within the (Python)Operator? For example:

def execute():
    if condition:
        skip_current_task()

task = PythonOperator(task_id='task', python_callable=execute, dag=some_dag)

跳过下游任务不适合我（此答案中提出的解决方案：如何在Airflow上跳过任务？），以及分支。有没有一种方法可以从操作员内部将任务的状态标记为跳过？

Skipping downstream tasks doesn't suit me (a solution proposed in this answer: How to skip tasks on Airflow?), as well as branching. Is there a way for a task to mark its state as skipped from within the Operator?

推荐答案

想通了！跳过任务很容易：

Figured it out! Skipping task is as easy as:

def execute():
    if condition:
        raise AirflowSkipException

task = PythonOperator(task_id='task', python_callable=execute, dag=some_dag)
