mysql分歧版本和仓库储存引擎选型的验证

v Myisam

 

//倘诺在IOS平台必要开辟相应的数据库路线

My.cnf配置

log-bin=mysql-bin 关闭,不要写日记

skip-networking 开启

 )

sqlite3_stmt * stmt =
DataBaseHelper::sharedDataBaseHelper()->queryTable(T::tableName(),
NULL, condition);

主要涉嫌:

 

}

v Mariadb

 out p_total_rows int

{

Mysql的版本和仓库储存引擎比较多,为了选用最相符业务应用的系统,供给实行自然的印证,本文描述mysql的印证进程和思路。

  /*预处理*/

std::vector res;

Isam存款和储蓄测量检验

class benchMyisamTest: public testing::Test {

public:

static void SetUpTestCase() {

//建构相应的表布局

std::string mysql = “/usr/local/mysql/bin/mysql
–default-character-set=utf8 -uroot -p123456 -D mysql -e \”source
myisam.sql\””;

system(mysql.c_str());

}

static void TearDownTestCase() {

}

};

TEST_F(benchMyisamTest, 1w100) {

insertOneSession(10000, 100);

}

TEST_F(benchMyisamTest, 1w1000) {

安装和布置

v mariadb5.5

v Oracle

v Tokudb

如上目录下有对应的装置,卸载脚本

具体步骤如下:

1.先是甘休mysql服务

a) service mysql stop / service mysqld stop

b) killall -9 mysql | killal -9 mysqld

c卡塔尔 /etc/profile中不用有mysql的意况变量设置

2.设置引擎

a卡塔尔(英语:State of Qatar) 以上的相继对应目录有安装的剧本

3.检验

a卡塔尔国 步入对应的设置目录下的bin目录

b卡塔尔 ./mysql -uroot -p123456 检查装置的版本新闻是或不是科学

c卡塔尔(英语:State of Qatar) show engines; show plugins; 能够查阅引擎的安装情状

4.运转单元测量检验验证各样引擎的品质

  execute stmt_count;

 

此外内燃机测试

和哪些近乎,你能够写出您自身的测量检验引擎

 p_order_string varchar(256),

 

正如是现实性的思路

  end if;

// android
系统不可能对assets目录下的文书进行fopen操作,所以copy到
/data/data/包名/files/ 上面再操作

底工插入函数

包括

v 迭代次数

v 存储包的大小:数据字段可安装大小

###是现实性的业务表

static void insertOneSession(int count, int size, bool canTruncate =
true){

### item = createItem(size);

cppdb::session session;

static const std::string sql =

“insert into `###`) \

VALUES ( ?, FROM_UNIXTIME(?), ?, ?, ?, ?, ?, \

INET_ATON(?), ?, ?, ?, ?, ?, \

?, ?, ?)”;

{

try {

session = cppdb::session(::common::base::BaseData::dbConnectString);

cppdb::statement stmt;

if (canTruncate) {

const static string ready = “TRUNCATE table ***”;

stmt = session.prepare(ready);

stmt.exec();

}

stmt = session.prepare(sql);

for (int i = 0; i < count; i++) {

stmt.reset();

stmt.bind(###);

stmt.exec();

}

} catch (std::exception const &e) {

LOG(ERROR)<< “saveDB:” << e.what();

}

// //关闭链接

if (session.is_open())

session.close();

}

{

//计算出表空间

session =

cppdb::session(

“mysql:user=root;password=123456;database=mysql;set_charset_name=utf8;
@pool_size=1”);

cppdb::statement stmt =

session.create_statement(

“select table_name,engine,ROUND(data_length/1024,2) size,table_rows
from information_schema.tables where table_schema=’###’ and
table_name=’traffic'”);

cppdb::result r = stmt.query();

while(r.next()){

www.hg888.com,string table_name, engine;

long size, table_rows;

r.fetch(table_name);

r.fetch(engine);

r.fetch(size);

r.fetch(table_rows);

LOG(INFO) <<“TableInfo::” << table_name << ” ”
<< engine <<” ” << size << ”
“<<table_rows;

}

if (session.is_open())

session.close();

}

}

 

return count;

v Oracle

 p_page_size int,

sprintf(condition, “id=%d”, tid);

具体的仓库储存引擎

  set @rows_total = 0;

}

Mysql的版本

/*分页程序*/ delimiter
// drop procedure if exists sp_page; create procedure sp_page(
p_table_name varchar(1024), p_fields varchar(1024), p_pag…

DataBaseTable(){}

结果

如下只是本身用的虚构机平台的结果,不意味着普适性

 

是具体的生机勃勃对装置和安插区别的数据库脚本

首要涉及: Mysql的…

  deallocate  prepare stmt_count;

{

v TokuDB

create procedure sp_page(

if ((sqlite3_step(stmt)==SQLITE_ROW))

v Innodb

表的名字 要查询的字段  每页显示的记录数  当前的页码  总记录数

void DataBaseHelper::destroy()

v Tokudb

  if p_curr_page<1 then

}

多线程存款和储蓄测量检验

#include <mysql.h>

//多少个办事线程的管理

int thread_Num, thread_Size;

void worker(){

insertOneSession(thread_Num, thread_Size);

}

void workerThread(int ts, int count, int size){

//四线程方式下必需选拔,不然mysql client库不能连接错误111

mysql_library_init(0, NULL, NULL);

thread_Num = count;

thread_Size = size;

    boost::thread_group threads;

    for (int i = 0; i < ts; ++i){

        threads.create_thread(&worker);

    }

    threads.join_all();

    LOG(INFO) << “done”;

//那些指鹿为马好像是libmysqlclient的兼容难点 Error in
my_thread_global_end(): 4 threads didn’t exit

mysql_library_end();

}

TEST_F(benchMyisamTest, thread_1w100) {

workerThread(2, 10000, 100);

}

TEST_F(benchMyisamTest, thread_30w) {

workerThread(3, 100000, 1000);
