什么是UUID? [英] What is a UUID?

问题描述

那么，什么是一个?

推荐答案

这是一个唯一标识事物的标识号. ID号的想法是通用唯一.因此，没有两件事应该具有相同的uuid.实际上，如果您要生成10万亿个uuid，则两个uuid相同的.00000006机会差不多.

It's an identification number that will uniquely identify something. The idea being that id number will be universally unique. Thus, no two things should have the same uuid. In fact, if you were to generate 10 trillion uuids, there would be something along the lines of a .00000006 chance of two uuids being the same.
