从补丁 198 开始，Amazon Redshift 将不再支持创建新的 Python UDF。现有的 Python UDF 将继续正常运行至 2026 年 6 月 30 日。有关更多信息，请参阅[博客文章](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/)。

# 监控计划查询
<a name="query-editor-v2-schedule-query-sns"></a>

对于您指定用于发送电子邮件通知的 Amazon SNS 主题，请使用查询编辑器 v2 创建 Amazon SNS 主题，方法是导航到 **SNS 通知**部分，**开启**监控，然后使用**创建 SNS 主题**来创建主题。查询编辑器 v2 创建 Amazon SNS 主题，并将服务主体添加到 Amazon EventBridge 的访问策略中。以下是在 Amazon SNS 主题中创建的示例**访问策略**。在示例中，使用了 AWS 区域 {{us-west-2}}、AWS 账户 {{123456789012}} 以及 Amazon SNS 主题 {{select-version-pdx-testunload}}。

计划查询运行时，Amazon SNS 会发送 AWS 通知电子邮件。以下示例显示了使用 Amazon SNS 通知主题 {{may25a-SNS}}，为 AWS 账户 {{123456789012}} 中在 AWS 区域 {{eu-north-1}} 上运行的计划查询 {{QS2-may25a}} 发送到 {{myemail@example.com}} 的电子邮件。

```
