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/)。 # 安全日志记录 如果 Amazon Redshift 记录引用一个或多个 AWS Glue Data Catalog 视图的查询，则 Amazon Redshift 在记录有关该查询的元数据时，会自动屏蔽某些系统表列和视图列中的字段。 安全日志屏蔽适用于 Amazon Redshift 在运行符合屏蔽条件的查询时生成的所有系统表和视图条目。下表列出了应用了安全日志记录、用 `******` 屏蔽文本和用 `-1` 屏蔽数字的系统视图和列。用于屏蔽文本的星号数量与原始文本中的字符数相匹配，最多 6 个字符。长度超过 6 个字符的字符串仍显示为 6 个星号。 **** | 系统表 | 敏感列 | | --- | --- | |
