内存分配器不仅会区别对待大小不同的对象,还会将内存分成不同的级别分别管理,TCMalloc 和 Go 运行时分配器都会引入线程缓存(Thread Cache)、中心缓存(Central Cache)和页堆(Page Heap)三个组件分级管理内存: 图1-6 多级缓存内存分配 线程缓存属于每一个独立的线程,它能够满足线程上绝大多数的内存分配需求,因为不涉...
fairly trivial to switch to an in-memory row cache 就不翻译了。简单来讲,vitess的作者也认为进程内的cache是更好的方案,由于当前golang的gc实现还不够理想, 所以选择了memcache。另外这里有篇文章分享了从ruby到golang到c的历程也说明go的gc还不够成熟。
