1. 概述 有时被称作发布/订阅模式,观察者模式定义了一种一对多的依赖关系,让多个观察者对象同时监听某一个主题对象.这个主题对象在状态发生变化时,会通知所有观察者对象,使它们能够自动更新自己. 2. 解决的问题 将一个系统分割成一个一些类相互协作的类有一个不好的副作用,那就是需要维护相关对象间的一致性.我们不希望为了维持一致性而使各类紧密耦合,这样会给维护.扩展和重用都带来不便.观察者就是解决这类的耦合关系的. 3. 模式中的角色 3.1 抽象主题(Subject):它把所有观察者对象的引用保存…

0x00 概述 Copy-On-Write简称COW,是一种用于程序设计中的优化策略.其基本思路是,从一开始大家都在共享同一个内容,当某个人想要修改这个内容的时候,才会真正把内容Copy出去形成一个新的内容然后再改,这是一种延时懒惰策略.从JDK1.5开始Java并发包里提供了两个使用CopyOnWrite机制实现的并发容器,它们是CopyOnWriteArrayList和CopyOnWriteArraySet.CopyOnWrite容器非常有用,可以在非常多的并发场景中使用到. 0x01 什么…

==copy 模块== ``copy`` 模块包含两个函数, 用来拷贝对象, 如 [Example 1-64 #eg-1-64] 所示. ``copy(object) => object`` 创建给定对象的 "浅/浅层(shallow)" 拷贝(copy). 这里 "浅/浅层(shallow)" 的意思是复制对象本身, 但当对象是一个容器 (container) 时, 它的成员仍然指向原来的成员对象. ====Example 1-64. 使用 copy 模块复…

最近有需要对数据进行迁移的需求,由于postgres性能的关系,单表3000W的数据量查询起来有一些慢,需要对大表进行切割,拆成若干个子表,涉及到原有数据要迁移到子表的需求.起初的想法是使用存储过程,使用select insert方式进行,但是数据量大的时候耗时有点久,于是需要想别的办法,就发现了postgres本身支持的copy命令. copy命令 COPY在PostgreSQL表和文件之间交换数据. COPY TO把一个表的所有内容都拷贝到一个文件,而COPY FROM从一个文件里拷贝数据到…
