【SysBench】OLTP 基准测试示例

2024-03-24 06:28

本文主要是介绍【SysBench】OLTP 基准测试示例,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!

前言

本文采用 MySQL 沙盒实例作为测试目标,使用 sysbench-1.20 对其做 OLTP 基准测试。

有关 MySQL 沙盒的更多信息,请参阅 玩转 MySQL Shell 沙盒实例,【MySQL Shell】6.8 AdminAPI MySQL 沙盒 。


1、部署一个 MySQL 沙盒实例

使用 mysqlsh 部署一个 MySQL 沙盒实例用于测试 OLTP 。

 MySQL  JS > dba.deploySandboxInstance(3310);
A new MySQL sandbox instance will be created on this host in 
/root/mysql-sandboxes/3310Warning: Sandbox instances are only suitable for deploying and 
running on your local machine for testing purposes and are not 
accessible from external networks.Please enter a MySQL root password for the new instance: ********Deploying new MySQL instance...Instance localhost:3310 successfully deployed and started.
Use shell.connect('root@localhost:3310') to connect to the instance.

2、创建 sysbench oltp 测试的基础配置文件

为什么要使用配置文件?方便快捷啊!配置文件可以简化操作,省着在命令行中指定这些参数时至少还要多打 -- 和空格。如果一些参数可以复用,建议创建一个配置文件。

$ cat mysql-sb.cnf 
threads=2
time=600db-driver=mysql
mysql-host=localhost
mysql-port=3310
mysql-socket=/root/mysql-sandboxes/3310/sandboxdata/mysqld.sock
mysql-user=root
mysql-password=Ro123ot$
mysql-db=sbtest

在创建时读者可能遇到一个问题,在配置文件中指定诸如 tables 选项时不生效,并且会报 Unknown argument type: 0 。而在命令行中指定时则有效。原因是什么呢?

因为这个参数是 Lua 脚本的参数,而不是 sysbench 这个二进制可执行文件的参数!

所以应该在命令行中使用诸如 --tables=N 这样的 Lua 脚本参数来测试。

3、准备测试数据

笔者准备了 100 个包含 10000 行数据的测试表,库名和表名都是用默认值。

$ sysbench --config-file=mysql-sb.cnf --tables=100 oltp_common prepare

注意此阶段的屏幕打印信息,多线程时可能出现争用,导致部分表未创建成功,或写入的数据不全。

sbtest6 创建失败报错:

计划创建 100 张表,实际只创建了 53 个,上面的 sbtest6 表虽然最后创建成功了,但插入的数据不全。

4、运行测试

1) oltp_read_write

建议先对支持 prewarm 选项的 Lua 脚本使用 prewarm 选项,以预热数据到内存,提高性能。

$ sysbench --config-file=mysql-sb.cnf --tables=100 oltp_read_write.lua prewarm

因输出过长,以下仅截取部分信息。

预热后:

$ sysbench --config-file=mysql-sb.cnf --tables=100 oltp_read_write.lua run
sysbench 1.0.20 (using bundled LuaJIT 2.1.0-beta2)Running the test with following options:

未预热,同时使用周期报告来每 5 秒生成一次报告信息:

3) oltp_write_only.lua

上面设置的 report-interval 每 5 秒报告一次太频繁了,笔者目的是为了演示 sysbench 的用法,因而选择后面不再报告了。

此外,这个测试我在命令行增加了开启直方图的参数 --histogram=on ,来看一下效果吧!

$ sysbench --config-file=mysql-sb.cnf --tables=100 oltp_write_only.lua run --histogram=on

MySQL 数据库内的执行结果如下:

 MySQL  localhost:3310 ssl  sbtest  SQL > select count(*) from sbtest1;
+----------+
| count(*) |
+----------+
| 28293831 |
+----------+
1 row in set (1.7266 sec)MySQL  localhost:3310 ssl  sbtest  SQL > select count(*) from sbtest2;
+----------+
| count(*) |
+----------+
| 28267618 |
+----------+
1 row in set (1.8061 sec)

我们可以修改 times 参数为一个较小的值,因为没有必要批量插入 10 分钟的数据。

$ sysbench --config-file=mysql-sb.cnf bulk_insert.lua prepare --time=60
$ sysbench --config-file=mysql-sb.cnf bulk_insert.lua run --time=60
sysbench 1.0.20 (using bundled LuaJIT 2.1.0-beta2)Running the test with following options:
Number of threads: 2
Initializing random number generator from current timeInitializing worker threads...Threads started!SQL statistics:queries performed:read:                            0write:                           190other:                           0total:                           190transactions:                        5722434 (94526.75 per sec.)queries:                             190    (3.14 per sec.)ignored errors:                      0      (0.00 per sec.)reconnects:                          0      (0.00 per sec.)General statistics:total time:                          60.5316stotal number of events:              5722434Latency (ms):min:                                    0.00avg:                                    0.02max:                                 1102.7995th percentile:                        0.00sum:                               118906.30Threads fairness:events (avg/stddev):           2861217.0000/0.00execution time (avg/stddev):   59.4532/0.19

可以看到再命令行最后指定的 --times=60 覆盖了配置文件中指定的 time=600

 MySQL  localhost:3310 ssl  sbtest  SQL > select 'sbtest1' table_name,count(*) from sbtest1 union all-> select 'sbtest1' table_name,count(*) from sbtest2;
+------------+----------+
| table_name | count(*) |
+------------+----------+
| sbtest1    |  2861217 |
| sbtest1    |  2861217 |
+------------+----------+
2 rows in set (0.4175 sec)

5、清理数据

$ sysbench --config-file=mysql-sb.cnf oltp_common.lua --tables=100 cleanup

在这里插入图片描述

6、销毁 MySQL 沙盒实例

mysqlsh 终端中执行:

 MySQL  localhost:3310 ssl  sbtest  JS > dba.stopSandboxInstance(3310)
The MySQL sandbox instance on this host in 
3310 will be stoppedPlease enter the MySQL root password for the instance 'localhost:3310': ********
The active session is established to the sandbox being stopped so it's going to be closed.Stopping MySQL instance...Instance localhost:3310 successfully stopped.MySQL  JS > dba.deleteSandboxInstance(3310);Deleting MySQL instance...Instance localhost:3310 successfully deleted.
