Redis：是否可以使数组或排序集中的元素过期？ [英] Redis: possible to expire an element in an array or sorted set?

问题描述

当前是否只能使整个键/值对失效？如果我想向列表类型结构中添加值并在插入后1小时自动删除它们该怎么办。目前是否可行，还是需要运行cron作业以手动进行清除？

Is it currently only possible to expire an entire key/value pair? What if I want to add values to a List type structure and have them get auto removed 1 hour after insertion. Is that currently possible, or would it require running a cron job to do the purging manually?

推荐答案

目前是否只能使整个键/值对失效？

Is it currently only possible to expire an entire key/value pair?

据我所知，并且根据到期的href = http://redis.io/commands#generic>密钥命令和文档您只能将过期设置为特定键，而不能设置为基础数据结构。但是，在Google网上论坛上有关于此功能的讨论，其中概述了替代解决方案。

As far as I know, and also according to key commands and document about expiration, currently you can set expiration only to specific key and not to it's underlying data structure. However there is a discussion on google groups about this functionality with outlined alternative solutions.
