Redis:可能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

目前是否只能使整个键/值对过期?如果我想将值添加到 List 类型结构并在插入后 1 小时自动删除它们，该怎么办.这是目前可能的，还是需要运行 cron 作业来手动进行清除?

解决方案

目前是否只能使整个键/值对过期?

据我所知，也根据key命令和关于expiration，目前您只能将过期设置为特定的键，而不是它的底层数据结构.但是，在 Google 群组上有一个关于此功能的讨论，并提供了概述的替代解决方案.>

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?

解决方案

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

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.
