背景介绍 传统数据库的主备架构,主备有各自的存储,备节点回放WAL日志并读写自己的存储,主备节点在存储层没有耦合.PolarDB的实现是基于共享存储的一写多读架构,主备使用共享存储中的一份数据.读写节点,也称为主节点或Primary节点,可以读写共享存储中的数据:只读节点,也称为备节点或Replica节点,仅能各自通过回放日志,从共享存储中读取数据,而不能写入.基本架构图如下所示: 一写多读架构下,只读节点可能从共享存储中读到两类数据页: 未来页:数据页中包含只读节点尚未回放到的数据,比如只读节…

前面在介绍Android系统的开机画面时提到,Android设备的显示屏被抽象为一个帧缓冲区,而Android系统中的SurfaceFlinger服务就是通过向这个帧缓冲区写入内容来绘制应用程序的用户界面的.Android系统在硬件抽象层中提供了一个Gralloc模块,封装了对帧缓冲区的所有访问操作.本文将详细分析Gralloc模块的实现,为后续分析SurfaceFlinger服务的实现打下基础. 在前面Android系统的开机画面显示过程分析一文中提到,Linux内核在启动的过程中会创建一个类…

针对一些运营商的锁网需求,MTK平台已经对其有很好的支持.绝大多数的海外需求可以通过直接配置相关文件来完成.这里简单描述一下配置方法,不做原理分析. 相关数据结构分析: Modem中与SML锁网配置相关的数据结构有: Sml_context_struct:SML上下文, cat:SML种类,目前MTK平台共支持7种锁网方式(Network Lock,Network Subset Lock,Service Provider Lock,Corporate Lock,IMSI Lock,Linked…

[本人原创],欢迎交流和分享技术,转载请附上如下内容: 作者:itshare [转自]http://www.cnblogs.com/itshare/ 通常我们知道,当一个日志借口被外部程序多个线程请求后,如果没有使用Buffer和异步写入IO的处理.CPU就会一直处于加锁和解锁的频繁切换,这样加上等待每次线程锁中的IO处理完毕的时间,高并发调用日志接口的整个过程中响应和处理速度就会严重变慢,并且让CPU一直居高不下. 这里,Coding First,先看对比结果,最后我再附上LogBufferP…

简单使用Lock锁 Java5中引入了新的锁机制--Java.util.concurrent.locks中的显式的互斥锁:Lock接口,它提供了比synchronized更加广泛的锁定操作.Lock接口有3个实现它的类:ReentrantLock.ReetrantReadWriteLock.ReadLock和ReetrantReadWriteLock.WriteLock,即重入锁.读锁和写锁.lock必须被显式地创建.锁定和释放,为了可以使用更多的功能,一般用ReentrantLock为其实例化…
