ES性能测试-esrally

es存储结构：

我们从es存储一个数据来分析es的结构：

index相当于我们的mysql中的数据库的database

_type相当于我们数据的表名

id：相当于我们表中的某一条主键id，也是一个唯一标识

version相当于数据的版本号

_source相当于我们的表数据，在es存储都是json数据

一.环境搭建
esrally 对于软件环境的要求如下：

Python 3.4+ 和 pip3
JDK 8
git 1.9+
执行pip3 install esrally静等几分钟就可以完成安装,如果在命令中没有显示请修改path变量则已经安装成功。

输入esrally -h或者esrally --version来判断是否已经安装完成。
执行一次压测“

esrally --distribution-version=5.0.0

结果如下：
