哪个Java阻塞队列对于单生产者单一消费者方案最有效 [英] Which Java blocking queue is most efficient for single-producer single-consumer scenarios

问题描述

我正在研究一个标准的Java系统，它对我的​​生产者有严格的时序要求（1 / 100s ms事项）。

I'm working on a standard Java system with critical timing requirements for my producers (1/100s of ms matters).

我有一个生产者将东西放在一个阻塞队列中，一个消费者随后拿起那些东西并将其转储到一个文件中。消费者在数据不可用时阻止。

I have a producer placing stuff in a blocking queue, and a single consumer later picking up that stuff and dumping it to a file. The consumer blocks when data is not available.

显然，阻塞队列是合适的接口，但是如果我想最小化生产者的成本，我应该选择哪种实际实现？当我把东西放进队列时，我想尽可能少地玩锁定和分配等东西，我不介意消费者是否需要等待更长时间或者更努力地工作。

Obviously, blocking queue is the appropriate interface, but which actual implementation should I choose if I want to minimize the cost to the producer? I wan to play as little as possible on things like locking and allocating when I am putting stuff in the queue, and I don't mind if the consumer has to wait a lot longer or work a lot harder.

是否有更快的实施，因为我只有一个消费者和单个生产者？

Is there an implementation that can be faster because I only have a single consumer and single producer ?

推荐答案

嗯，确实没有太多选择。让我来看看列出的子类 ：

Well, there really aren't too many options. Let me go through the listed subclasses:

DelayQueue ， LinkedBlockingDeque ， PriorityBlockingQueue ，以及 SynchronousQueue 全部为需要额外功能的特殊情况而制作;在这种情况下，它们没有意义。

DelayQueue, LinkedBlockingDeque, PriorityBlockingQueue, and SynchronousQueue are all made for special cases requiring extra functionality; they don't make sense in this scenario.

只留下 ArrayBlockingQueue 和 LinkedBlockingQueue 。如果您知道如何判断是否需要 ArrayList 或 LinkedList ，您可以自己回答这个问题。

That leaves only ArrayBlockingQueue and LinkedBlockingQueue. If you know how to tell whether you need an ArrayList or a LinkedList, you can probably answer this one yourself.

请注意，在 LinkedBlockingQueue 中，每次插入时都会动态创建链接节点;这可能会推动你走向 ArrayBlockingQueue 。

Note that in LinkedBlockingQueue, "linked nodes are dynamically created upon each insertion"; this might tend to push you toward ArrayBlockingQueue.
