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/)。

# 主集群的 SVL 视图
<a name="svl_views"></a>

SVL 视图是 Amazon Redshift 中的系统视图，其中包含对 STL 表和日志的引用以提供更多详细信息。

这些视图提供对在这些表中找到的常用查询数据的更快速、更便捷的访问。

**注意**  
SVL\$1QUERY\$1SUMMARY 视图只包含有关 Amazon Redshift 运行的查询的信息，不包含其它实用工具和 DDL 命令执行的查询的相关信息。有关 Amazon Redshift（包括 DDL 和实用工具命令）运行的所有语句的完整列表和信息，请查询 SVL\$1STATEMENTTEXT 视图。
