推荐答案
不，DynamoDB 中没有可用的保留"设置.
No, there is no "retention" setting available in DynamoDB.
您可以运行使用日期字段过滤结果的每日/每月查询，并使用该输出来确定要删除的项目.这需要在您自己的编程代码中实现.
You could run a daily/monthly query that uses a date field to filter results, and use that output to determine which Items to delete. This would need to be implemented in your own programming code.
一些用户选择使用单独的表来提供老化.例如，为每个月创建一个单独的表.然后，一旦旧表超过一定年龄，就删除它们.但是，您的软件必须知道如何处理多个数据表.
Some users choose to use separate tables to provide ageing. For example, create a separate table for each month. Then, delete old tables once they pass a certain age. However, your software would have to know how to handle multiple tables of data.
