DynamoDB：将TTL设置到项目中，它还显示时间但未删除记录
DynamoDB: set TTL into the items and also it shows time but record not deleted
我已将 ttl 设置为 TTL 列，并为某些项目添加纪元时间。
但是我发现它没有被删除。这是为什么？
Depending on the size and activity level of a table, the actual delete operation of an expired item can vary. Because TTL is meant to be a background process, the nature of the capacity used to expire and delete items via TTL is variable (but free of charge). TTL typically deletes expired items within 48 hours of expiration.
不建议将 TTL 用于业务关键操作。
