关于数据库:使用TPCH-进行GreatSQL并行查询测试

筹备工作

数据库版本

GreatSQL-8.0.25-17

生成数据

应用 TPC-H 生成数据

#TPC-H Population Generator (Version 3.0.0)

#生成 10G 的数据
$ ./dbgen -vf -s 10

批改 my.cnf

vim /etc/my.cnf 

#设置 IPB 为 8G
innodb_buffer_pool_size = 8G

#设置并行查问的应用最大内存(此处为 8G，依据具体配置设置)
parallel_memory_limit= 8G

#关上并行查问
force_parallel_execute=1

 #设置双 1（不便导入数据）innodb_flush_log_at_trx_commit = 1 
sync_binlog = 1

#敞开 binlog
skip-log_bin

datadir    = /data/GreatSQL
socket    = mysql.sock

启动数据库后，能够查看配置是否失效

mysql> show variables like '%double%';
mysql> show variables like 'log_bin';
mysql> show variables like 'sync_binlog';
mysql> show variables like 'innodb_flush_log_at_trx_commit';
mysql> show variables like 'innodb_buffer_pool_size';

并行查问相干参数

mysql> show global variables like '%parall%';
+----------------------------------+----------------+
| force_parallel_execute           | ON             |
| innodb_parallel_dblwr_encrypt    | OFF            |
| innodb_parallel_doublewrite_path | xb_doublewrite |
| innodb_parallel_read_threads     | 4              |
| parallel_cost_threshold          | 1000           |

+----------------------------------+----------------+
11 rows in set (0.01 sec)

启动数据库

启动数据库：

$ systemctl start greatsql.service 

文件筹备

本次的工作在 /data/tpch

可执行程序为 dbgen, 依赖一个数据分布文件 dists.dss。能够将 dbgen 和 dists.dss 拷贝到同一目录应用

dss.ddl 和 dss.ri 文件

筹备表构造和索引文件 dss.ddl 和 dss.ri 到工作目录

$ cd /data/tpch/tpch_2.18.0/dbgen
$ cp dss.ri /data/tpch/
$ cp dss.ddl /data/tpch/

load.sql

批改 load.sql 文件 批改文件的门路

$ cd /data/tpch/
$ cp load.sql loadfix.sql 
$ vim loadfix.sql

导入数据

$ /usr/localGreatSQL-8.0.25-17/bin/mysql -uroot -S /data/GreatSQL/mysql.sock

#创立数据库
mysql> create database tpch;
mysql> use tpch;

#导入表构造
mysql> source /data/tpch/dss.ddl;

#导入数据（文件见附录）mysql> sh loadfile

#导入索引、外键等
mysql> source /data/tpch/dssfix.ri

注：binlog 要关再导入, 否则 binlog 会爆

Multi-statement transaction required more than 'max_binlog_cache_size' bytes of storage; increase this mysqld variable and try again

查看导入的表（20G 数据）

mysql> select table_name,table_rows 
from information_schema.tables 
where table_name in 
('customer','lineitem','nation','orders','part','partsupp','region','supplier');

+------------+------------+
| TABLE_NAME | TABLE_ROWS |
+------------+------------+
| region     |          5 |
| nation     |         25 |
| part       |    3860136 |
| supplier   |     197853 |
| customer   |    2884322 |
| partsupp   |   17084176 |
| orders     |   29678499 |
| lineitem   |   87786966 |
+------------+------------+
8 rows in set (0.00 sec)

编写并运行测试脚本

# 测试脚本见附录
#这里是在 tmux 中运行，防止因为终端敞开导致测试终止
$ sh auto.sh&

#测试完结后在以后脚本的目录查看生成的日志
$ cat tpch-PQ-******.log

测试运行时，察看相干指标。

mysql> show global status like '%PQ%';
+--------------------+-------+
| Variable_name      | Value |
+--------------------+-------+
| PQ_memory_refused  | 0     |
| PQ_memory_used     | 0     |
| PQ_threads_refused | 0     |
| PQ_threads_running | 0     |
+--------------------+-------+
4 rows in set (0.00 sec)


mysql> show processlist;
mysql> explain for connection **;

测试后果

开启并行查问（16 线程）的执行工夫，与不开启并行查问的执行工夫如下：

注：本文章重点讲测试过程，具体的测试后果就不开展了。

测试脚本：

脚本是七拼八凑的，写的不好，心愿有大佬能领导一下
