水塘抽样是一系列的随机算法，其目的在于从包含n个项目的集合S中选取k个样本，其中n为一很大或未知的数量，尤其适用于不能把所有n个项目都存放到主内存的情况。 在高德纳的计算机程序设计艺术中，有如下问题： 可否在一未知大小的集合中，随机取出一元素？ 。或者是Google面试题： I have a lin

传统算法的典型问题：
比较差的内存访问局部性
针对单个顶点的处理工作过少
计算过程中伴随着并行度的改变

蓄水池抽样解决的问题是当不知道N的大小时从N个数中等概率抽取k个数。
要理解这个问题，首先从抽取一个数来看。
在知道数字总数N的大小的情况下，我们可以很容易的用C运行库的rand函数随机

离线计算（Offline Computing）和边缘计算（Edge Computing）是两种不同的计算范式，它们在数据处理的位置、时间以及目的方面都有显著区别。离线计算 (Offline Computing)离线计算是指在非实时环境下进行的数据处理和计算任务。主要特点包括：处理时间：不是实时处理，通常在后台或批处理模式下进行数据来源：数据通常从主系统导出，在专门的计算环境中处理处理目的：主要用于
