influxdb mysql对比_InfluxDB和MySQL的读写对比测试

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

操作系统： CentOS6.5_x64

InfluxDB版本： v1.1.0

MySQL版本：v5.1.73

CPU ： 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

初始化SQL语句：

CREATE DATABASEtestMysql;CREATE TABLE`monitorStatus` (

`system_name`VARCHAR(20) NOT NULL,

`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;

单写测试代码(insertTest1.c)：

#include #include#include#include"mysql/mysql.h"

#define N 100

intmain() { MYSQL*conn_ptr;intres;intt,i,j;

int64_t tstamp= 1486872962;

srand(time(NULL));

t=0;

conn_ptr=mysql_init(NULL);if (!conn_ptr)

{

printf("mysql_init failed\n");returnEXIT_FAILURE;

}

conn_ptr= mysql_real_connect(conn_ptr,"localhost","root","","testMysql",0,NULL,0);if(conn_ptr)

{for(i=1;i<= 10000;i++)

{

mysql_query(conn_ptr,"begin");for(j=0;j

{char query[1024]={0};

sprintf(query,"insert into monitorStatus values ('sys_%d','s_%d','e_%d','0.%02d','%lld');",//j%10,(t+i)%10,(t+j)%10,(t+i+j)%100,tstamp);

j%10,(t+i)%10,(t+j)%10,rand()%100,tstamp);//printf("query : %s\n",query);

res =mysql_query(conn_ptr,query);if (!res)

{//printf("Inserted %lu rows\n",(unsigned long)mysql_affected_rows(conn_ptr));

}else{

fprintf(stderr,"Insert error %d: %sn",mysql_errno(conn_ptr),mysql_error(conn_ptr));

}if(j%10 == 0) tstamp+=1;

}

mysql_query(conn_ptr,"commit");//printf("i=%d\n",i);

}

}else{

printf("Connection failed\n");

}

mysql_close(conn_ptr);returnEXIT_SUCCESS;

}

可根据情况调整测试代码中的N参数。

单读测试代码(queryTest1.c)：

#include #include#include"mysql/mysql.h"

intmain()

{

MYSQL*conn_ptr;

MYSQL_RES*res_ptr;

MYSQL_ROW sqlrow;

MYSQL_FIELD*fd;intres, i, j;

conn_ptr=mysql_init(NULL);if (!conn_ptr)

{returnEXIT_FAILURE;

}

conn_ptr= mysql_real_connect(conn_ptr,"localhost","root","","testMysql", 0, NULL, 0);if(conn_ptr)

{

res= mysql_query(conn_ptr,"select * from `monitorStatus` where system_name='sys_8' and site_name='s_9' and equipment_name='e_6' order by timestamp desc limit 10000;");if(res)

{

printf("SELECT error:%s\n",mysql_error(conn_ptr));

}else{

res_ptr=mysql_store_result(conn_ptr);if(res_ptr)

{

printf("%lu Rows\n",(unsigned long)mysql_num_rows(res_ptr));

j=mysql_num_fields(res_ptr);while((sqlrow =mysql_fetch_row(res_ptr)))

{continue;for(i = 0; i < j; i++)

printf("%s\t", sqlrow[i]);

printf("\n");

}if(mysql_errno(conn_ptr))

{

fprintf(stderr,"Retrive error:s\n",mysql_error(conn_ptr));

}

mysql_free_result(res_ptr);

}

}else{

printf("Connection failed\n");

}

mysql_close(conn_ptr);returnEXIT_SUCCESS;

}

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)：

du -sh /var/lib/mysql

查询特定表：

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

二、InfluxDB读写测试

测试准备

需要将InfluxDB的源码放入 go/src/github.com/influxdata 目录

单写测试代码(write1.go)：

package main

import ("log"

"time"

"fmt"

"math/rand"

"github.com/influxdata/influxdb/client/v2")const(

MyDB= "testInfluxdb"username= "root"password= "") func queryDB(clnt client.Client, cmdstring) (res []client.Result, err error) {

q :=client.Query{

Command: cmd,

Database: MyDB,

}if response, err := clnt.Query(q); err ==nil {if response.Error() !=nil {returnres, response.Error()

}

res=response.Results

}else{returnres, err

}returnres, nil

}

func writePoints(clnt client.Client,numint) {

sampleSize := 1 * 10000rand.Seed(42)

t :=num

bp, _ :=client.NewBatchPoints(client.BatchPointsConfig{

Database: MyDB,

Precision:"us",

})for i := 0; i < sampleSize; i++{

t+= 1tags := map[string]string{"system_name": fmt.Sprintf("sys_%d",i%10),"site_name":fmt.Sprintf("s_%d", (t+i) % 10),"equipment_name":fmt.Sprintf("e_%d",t % 10),

}

fields := map[string]interface{}{"value" : fmt.Sprintf("%d",rand.Int()),

}

pt, err := client.NewPoint("monitorStatus", tags, fields,time.Now())if err !=nil {

log.Fatalln("Error:", err)

}

bp.AddPoint(pt)

}

err :=clnt.Write(bp)if err !=nil {

log.Fatal(err)

}//fmt.Printf("%d task done\n",num)

}

func main() {//Make client

c, err :=client.NewHTTPClient(client.HTTPConfig{

Addr:"http://localhost:8086",

Username: username,

Password: password,

})if err !=nil {

log.Fatalln("Error:", err)

}

_, err= queryDB(c, fmt.Sprintf("CREATE DATABASE %s", MyDB))if err !=nil {

log.Fatal(err)

}

i := 1

for i <= 10000{

defer writePoints(c,i)//fmt.Printf("i=%d\n",i)

i += 1}//fmt.Printf("task done : i=%d \n",i)

}
