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://www.amazonaws.cn/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/)。

# SVV 元数据视图
<a name="svv_views"></a>

SVV 视图是 Amazon Redshift 中的系统视图，其中包含有关数据库对象的信息。请注意，尽管它们存储诸如用户权限或表名称之类的信息，但它们并不适用于联接用户创建的关系。

**注意**  
如果数据库响应因任何原因失败，Amazon Redshift 会报告 WARNING 而不是 ERROR。当您在数据共享中查询对象时，Amazon Redshift 不会发送 ERROR 消息。
