使用 AWS CloudFormation 模板创建用于 AWS 的外部函数¶

这些主题详细说明了如何使用 AWS (Amazon Web Services) CloudFormation 模板来创建在 AWS 上托管的外部函数。

Snowflake provides a sample template that you can start with. This template hides some details of the creation process. When you are ready to create your own custom external function, you can either customize a copy of the template or you can use the AWS Management Console to create the function.

这些主题假定您已熟悉 AWS 管理控制台。它们描述了您需要完成的一般步骤，但没有详细描述控制台。
