Webb一、什么是延时队列. 延时队列相比于普通队列最大的区别就体现在其延时的属性上，普通队列的元素是先进先出redis实现延迟队列，按入队顺序进行处理，而延时队列中的元素在入队时会指定一个延迟时间，表示其希望能够在经过该指定时间后处理。 从某种意义上来讲，延迟队列的结构并不像一个 ...

WebbTicks per Wheel (Wheel Size) HashedWheelTimer maintains a data structure called 'wheel'. To put simply, a wheel is a hash table of TimerTask s whose hash function is 'dead line … Webb下边会介绍多种实现延时队列的思路，文末提供有几种实现方式的 github地址。其实哪种方式都没有绝对的好与坏，只是看把它用在什么业务场景中，技术这东西没有最好的只有最合适的。 一、延时队列的应用 什么是延时队列？顾名思义：首先它要具有队列的特性，再给它附加一个延迟消费队列消息 ...
WebbAnd timeUnit (time unit), for example, when ticksPerWheel = 60, tickDuration = 1, timeUnit = second, this is completely similar to the actual second hand movement in reality. A simple implementation is given here. The pointer rotates at a fixed frequency according to the tickDuration setting. The necessary conventions are as follows: Webbint ticksPerWheel - the size of the wheel; boolean leakDetection - true if leak detection should be enabled always, if false it will only be enabled if the worker thread is not a daemon thread. Exception. The method HashedWheelTimer() throws the following exceptions: NullPointerException - if either of threadFactory and unit is null
