Airflow 2.0 API,是一种通过修饰函数,方便对图和任务进行定义的编码方式,主要差别是2.0以后前一个任务函数作为后一个任务函数的参数,通过这种方式来定义不同任务之间的依赖关系。 AIRFLOW_HOME 是 Airflow 寻找 DAG 和插件的基准目录。当数据工程师开发完python脚本后,需要以DAG模板的方式来定义任务流,然后把dag文...

定义第一个 DAG 在AIRFLOW_HOME 目录下新建 DAGs 文件夹,后面的所有 DAG 文件都要存储在这个目录。 新建demo.py,语句含义见注释。 from datetime import datetime, timedelta from airflow import DAG from airflow.utils.dates import days_ago from airflow.operators.bash_operator import BashOperator from air...
AIRFLOW_HOME 是 Airflow 寻找 DAG 和插件的基准目录。当数据工程师开发完python脚本后,需要以DAG模板的方式来定义任务流,然后把dag文件放到AIRFLOW_HOME下的DAG目录,就可以加载到airflow里开始运行该任务。 安装Airflow Airflow适合安装在linux或者mac上,官方推荐使用linux系统作为生产系统。如果要在windows安装,就需...
7 Users can specify a logs folder in airflow.cfg. By default, it is in the AIRFLOW_HOME directory. Logs are stored in the log folder as {dag_id}/{task_id}/{execution_date}/{try_number}.log. ...
Apache Airflow (or simply Airflow) is a platform to programmatically author, schedule, and monitor workflows.When workflows are defined as code, they become more maintainable, versionable, testable, and collaborative.Use Airflow to author workflows as directed acyclic graphs (DAGs) of tasks. The ...
