The queue can take advantage of extra per-producer and per-consumer storage if it's available to speed up its operations. This takes the form of 'tokens': You can create a consumer token and/or a producer token for each thread or task (tokens themselves are not thread-safe), and use ...

这样,Seastar对分配给自己的物理内存也进行了分片(shard),每个core有自己的内存空间,有自己的memory allocator(log-structured)对内存区域进行分配和释放管理,无需考虑thread safe和内存碎片化(定期compact,移动object,合并memory holes)。下图对比了基于JVM和Seastar的内存管理: 网络shard 所有的网络连接在cores之间分片(...

multiprocessing模块的功能众多:支持子进程、通信和共享数据、执行不同形式的同步,提供了Process、Queue、Pipe、Lock等组件。 需要再次强调的一点是:与线程不同,进程没有任何共享状态,进程修改的数据,改动仅限于该进程内。 1.2 Process类的介绍 创建进程的类: ...
Incoming commands fired from everywhere fill up an internal CThread command queue and are handled sequentially in the same order they were fired - first-in-first-out (cyclic stack mechanism). For example, the calling sequence: Start(), Pause(), Continue(), Stop() fired in one step will ...
断言,是宏,而非函数。assert 宏的原型定义在<assert.h>(C)、<cassert>(C++)中,其作用是如果它的条件返回错误,则终止程序执行。可以通过定义NDEBUG来关闭 assert,但是需要在源代码的开头,include <assert.h>之前。 使用 代码语言:javascript 代码运行次数:0 ...

To avoid data loss, if all specified Redis server are down, Eredis will keep in memory the last unsent QUEUE_MAX_UNSHIFT (10000) commands. If a Redis server goes down and up, it could be needed to resynchronize with an active node. The master-slave mechanism is perfect for that. In ...
