ArrayBlockingQueue 是 BlockingQueue 接口的有界队列实现类,底层采用数组来实现。ArrayBlockingQueue 一旦创建,容量不能改变。其并发控制采用可重入锁来控制,不管是插入操作还是读取操作,都需要获取到锁才能进行操作。当队列容量满时,尝试将元素放入队列将导致操作阻塞;尝试从一个空队列中取一个元素也会同样阻塞。

The configuration for Indexed and Vanilla Chronicle was entirely in code so the reader had to have the same configuration as the writers and it wasn’t always clear what that was. There was no way for the producer to know how much data had been replicated to the a second machine. The on...
