Jedis.expire介绍

[英]Set a timeout on the specified key. After the timeout the key will be automatically deleted by the server. A key with an associated timeout is said to be volatile in Redis terminology.

Volatile keys are stored on disk like the other keys, the timeout is persistent too like all the other aspects of the dataset. Saving a dataset containing expires and stopping the server does not stop the flow of time as Redis stores on disk the time when the key will no longer be available as Unix time, and not the remaining seconds.

Since Redis 2.1.3 you can update the value of the timeout of a key already having an expire set. It is also possible to undo the expire at all turning the key into a normal key using the #persist(String) command.

Time complexity: O(1)
[中]在指定的密钥上设置超时。超时后，服务器将自动删除密钥。在Redis术语中，具有相关超时的密钥称为易失性密钥。
易失性键像其他键一样存储在磁盘上，超时也像数据集的所有其他方面一样是持久的。保存包含expires的数据集并停止服务器不会停止时间流，因为Redis会在磁盘上存储密钥不再作为Unix时间可用的时间，而不是剩余的秒数。
由于Redis 2.1.3，您可以更新已设置过期的密钥的超时值。还可以使用#persist（String）命令将密钥转换为普通密钥，从而完全撤消过期。
时间复杂度：O（1）
