The timer wheel is a collection of buckets in which each bucket represents a chunk of time in the future for timer expiration.
时间轮是一个buckets集合,其中每个bucker 表示将来计时器过期的一个时间块。
The original timer implementation simply kept timers doubly linked in expiration order.
原始计时器实现只是按照过期顺序将计时器实现双重链接。
With an initialized timer, the user now needs to set the expiration time, which is done through a call to mod_timer.
拥有一个经过初始化的计时器之后,用户现在需要设置过期时间,这通过调用mod _ timer来完成。
From a user's perspective, timer_list contains an expiration time, a callback function (when/if the timer expires), and a user-provided context.
从用户角度看,timer_list包含一个过期时间,一个回调函数(当/如果计时器过期),以及一个用户提供的上下文。
So you need to use a timer or a separate process to handle expiration of keys.
所以你需要使用一个计时器或一个单独的进程来处理密钥的过期。
