pt-online-schema-change 测试使用-包含生成测试数据

# 参考网址： https://www.2cto.com/database/201703/618280.html

一、简要描述

1、mysql创建测试表

drop table IF EXISTS t_user;

CREATE TABLE `t_user` (

  `id` bigint(20) NOT NULL AUTO_INCREMENT,

  `name` varchar(255) DEFAULT NULL,

  `age` tinyint(4) DEFAULT NULL,

  `create_time` datetime DEFAULT NULL,

  `update_time` datetime DEFAULT NULL,

  PRIMARY KEY (`id`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

2、生成测试数据

delimiter //

DROP PROCEDURE IF EXISTS proc_batch_insert;

CREATE PROCEDURE proc_batch_insert()

BEGIN

DECLARE pre_name BIGINT;

DECLARE ageVal INT;

DECLARE i INT;

SET pre_name=187635267;

SET ageVal=100;

SET i=1;

WHILE i <= 10000000 DO

        INSERT INTO t_user(`name`,age,create_time,update_time) VALUES(CONCAT(pre_name,'@qq.com'),(ageVal+1)%30,NOW(),NOW());

SET pre_name=pre_name+100;

SET i=i+1;

END WHILE;

END //

delimiter ;

call proc_batch_insert();
