第 11章
流水线第一部分：
Apache Beam
和
Apache Airflow
前面章节中介绍了使用
TFX
构建机器学习流水线的所有必要组件。本章会将所有组件放在
一起，并展示如何使用两个编排器（
Apache Beam
和
Apache
Airflow
）来运行整条流水线。
第
12
章还将展示如何使用
Kubeflow
Pipelines
运行流水线。所有这些工具都遵循相似的原
理，但是我们将展示细节之间的差异，并为每个工具提供示例代码。
正如第
1
章所讨论的那样
，流水线编排工具对于抽象胶水代码至关重要，否则我们将需要
自己编写胶水代码来自动执行机器学习流水线。如图
1
1-1
所示，流水线编排器位于前面各
章已经提到的组件之下。如果没有这些编排工具，我们将需要编写代码来检查一个组件何
时完成、启动下一个组件、安排流水线的运行，等等。幸运的是，所有这些代码已经以这
些编排器的形式存在！
