Disruptor模块

LMAX-Disruptor的C#精简实现,保留其核心设计,更好的抽象和扩展性。

先上架构图:Disruptor架构图

与LMAX的Disruptor差异

  1. RingBuffer仅是数据结构,没有额外的职责。
  2. Sequencer是协调的集成,而不是生产者屏障,生产者屏障有明确的抽象。
  3. 协调的基本单位是屏障Barrier,依赖的单位也是屏障,而不是序列Sequence
  4. 反转了Barrier和Consumer之间的Sequence依赖。
  5. 剥离了Blocker和WaitStrategy,消费者可以使用不同的等待策略,但使用同一个Blocker。
  6. 库只提供了核心的协调功能,并没有提供BatchEventProcessor这样的具体组件,完全由用户控制。
  7. 内置了一套无界缓冲区MpUnboundedBuffer

ps: 很自信地讲,我的设计更容易理解。

C#实现与Java实现的不同

  1. C#的挂起最小单位是毫秒,而1毫秒已是非常长的时间,因此所有Sleep等待策略都没有让用户指定睡眠时间,而是固定1毫秒。
  2. C#的Thread.SpinWait方法提供了iterations参数,因此所有的SpinWait策略都提供了该参数支持。
  3. C#的不直接支持C++11的 Acquire和Release内存语义,因此使用Volatile读写代替。
  4. C#不支持volatile修饰64位的long和double,因此一些long类型字段未声明为volatile,这与我的日常习惯不同 -- 可能多线程读写的字段,保持为volatile是个好习惯。
  5. 为支持结构体类型,DataProvider提供了获取元素引用的ProducerGetRefConsumerGetRef接口。

PS:C#其实可以采用FieldOffset来实现缓存行填充,但为了保持代码简单,暂未采用

注意事项:

  1. C#的挂起最小单位是毫秒,因此慎重使用可能导致线程挂起的api,可能导致较大的延迟。
  2. 框架的具体应用见并发库中的DisruptorEventLoop
