The more preferable approach to installing Apache-Airflow is to install it in a virtual environment. Airflow requires the latest version ofPYTHONandPIP(package installer for python). 安装Apache-Airflow的更可取的方法是将其安装在虚拟环境中。Airflow需要最新版本的PYTHON和PIP(用于Python的软件包安装程序)...

Apache Airflow是一个提供基于DAG(有向无环图)来编排工作流的、可视化的分布式任务调度平台(也可单机),与Oozie、Azkaban等调度平台类似。Airflow在2014年由Airbnb发起,2016年3月进入Apache基金会,在2019年1月成为顶级项目。Airflow采用Python语言编写,并提供可编程方式定义DAG工作流(编写Python代码)。当工作流通过代码...
