前文提到了MySQL性能测试之insert&delete【FunTester框架】,今天来分享一下FunTester框架MySQL性能测试对于select
和update
语句进行性能测试。
准备工作这里就不细说了,有兴趣可以翻翻上面的文章链接。
select
这个语句应该是最常用的,而且优化的可能性比较大,各类添加索引的方式。随着数据量的增长还会涉及到分库分表等等。这里我简单演示一个最简单的select语句,配合上对于字段age
的可视化。
SQL语句准备:"SELECT * FROM funtesters WHERE age = ${getRandomInt(100)};"
这里age参数用了100内的随机参数,如果大家在做业务测试的时候可以使用更加灵活的方式进行参数化。
测试脚本

static final int thread = 10
static final int times = 100
public static void main(String[] args) {
RUNUP_TIME = 0
def task = []
thread.times {
task << new FunTester()
}
new Concurrent(task, "FunTester框架测试MySQL").start()
FunLibrary.testOver()
}
private static class FunTester extends FixedThread {
def connection = getConnection(url, "root", "root123456")
def statement = getStatement(connection)
FunTester() {
super(null, times, true)
}
@Override
protected void doing() throws Exception {
statement.execute("SELECT * FROM funtesters WHERE age = ${getRandomInt(100)};")
}
@Override
protected void after() {
super.after()
close(connection, statement)
}
@Override
FixedThread clone() {
return new FunTester(limit)
}
}
}

不知道是不是因为我没有加索引的原因,QPS太低了。
update
update也是在工作中经常用的数据库操作,对于这个操作我曾经写过两篇文章来区分两种不同update的参数化差别,如下如何对单行多次update接口进行压测、如何对多行单次update接口进行压测,有兴趣可以读一读。
这里只演示一个比较简单的方案,通过ID锁定某一行,然后对name
字段进行多次更新,这样可以基本避免update的值前后一致的情况。
测试脚本
代码语言:javascript复制
import com.funtester.base.constaint.FixedThread
import com.funtester.db.mysql.SqlBase
import com.funtester.frame.execute.Concurrent
import com.funtester.httpclient.FunLibrary
import com.funtester.utils.StringUtil
/**
* MySQL insert语句实践
*/
class MysqlUpdate extends SqlBase {
static final String url = "jdbc:mysql://localhost:3306/funtester?useUnicode=true&characterEncoding=utf-8&useOldAliasMetadataBehavior=true&useSSL=false"
static final int thread = 10
static final int times = 500
public static void main(String[] args) {
RUNUP_TIME = 0
def task = []
thread.times {
task << new FunTester()
}
new Concurrent(task, "FunTester框架测试MySQL").start()
FunLibrary.testOver()
}
private static class FunTester extends FixedThread {
def connection = getConnection(url, "root", "root123456")
def statement = getStatement(connection)
def id
FunTester() {
super(null, times, true)
id = getRandomRange(30, 10000)
}
@Override
protected void doing() throws Exception {
statement.execute("UPDATE funtesters SET name="${StringUtil.getString(20)}" WHERE id = $id;")
}
@Override
protected void after() {
super.after()
close(connection, statement)
}
@Override
FixedThread clone() {
return new FunTester(limit)
}
}
}
这里我在FunTester
类里面增加了一个属性id,用来标记修改行,这个范围是我从数据库中查到的,这里在工作中最好通过脚本实现,避免随机到不存在的行的情况。也可以将随机方式作用于SQL语句中,这样达到对多行进行修改的目的。

FunTester测试框架对于MySQL的性能测试告一段落,下期我会使用Go语言的gorm框架重写一个对MySQL进行性能测试的Demo,敬请期待。
