InfluxDB读写性能测试

这里将告诉您InfluxDB读写性能测试,教程操作步骤:

今天进行了InfluxDB和MySQL的对比测试,这里记录下结果,也方便我以后查阅。

操作系统: CentOS6.5_x64InfluxDB版本 : v1.1.0MySQL版本:v5.1.73CPU : Intel(R) Core(TM) i5-2320 CPU @ 3.00GHz内存 :12G硬盘 :SSD

一、MySQL读写测试 测试准备

CREATE TABLE `monitorStatus` (

     `site_name` VARCHAR(50) NOT NULL,
     `equipment_name` VARCHAR(50) NOT NULL,
     `current_value` DOUBLE NOT NULL,
     `timestamp` BIGINT(20) NULL DEFAULT NULL,
     INDEX `system_name` (`system_name`),
     INDEX `site_name` (`site_name`),
     INDEX `equipment_name` (`equipment_name`),
     INDEX `timestamp` (`timestamp`)
)
ENGINE=InnoDB;

测试数据记录

磁盘空间占用查询:

使用du方式(新数据库,仅为测试):

?
code
1
du -sh /var/lib/mysql

查询特定表:

?
code
1
2
use information_schema;
select concat(round(sum(DATA_LENGTH/1024/1024), 2), 'MB' ) as data from TABLES where table_schema= 'testMysql' and table_name= 'monitorStatus' ;
