I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.

节省开支并提升性能
大多数的流水线编排引擎支持一些种类的步骤缓存（
step caching
），以避免重复执
行未被更改的步骤。这被称为流水线“步骤缓存”。且由于流水线通常构建于诸如
SageMaker
训练任务等原语（
primitives
）之上，我们将强调
SageMaker
流水线用到

SageMaker
训练任务开销的作用。

缓存流水线步骤
在某些场景下，
我们可以重用之前成功的流水线步骤的结果并避免再次执行这些步
骤。
SageMaker
流水线通过检查之前使用相同输入构件和参数的成功步骤执行，以
支持步骤缓存。其他的编排器也支持步骤缓存，包括
