9.1. 迁移插件安装
中断安装比如 kill 掉java进程安装失败也要等待300s
下载安装包准备上传
缺少mysqlclient lib包
mysql如果是二进制安装的话我这个版本是没有18这个lib包的
安装成功后的截图 主机上有对应的进程 10. 全量迁移
10.1. 选中主机启动迁移 10.2. 迁移中 10.3. 迁移结束 10.4. 日志所在目录 11. 增量迁移
11.1. PG里面创建第二个库 11.2. 创建在线迁移任务 11.3. 启动
11.4. 在mysql端进行DDL和DML
mysql 端进行了5个事务
第6次增量
停止增量 12. 反向迁移 12.1. 在PG端进行增删改
12.2. PG端DDL 9. 离线迁移 9.1. 迁移插件安装

11.1. PG里面创建第二个库
create database world2 with dbcompatibilityb; 11.2. 创建在线迁移任务 11.3. 启动 全量迁移完成并校验成功后进入增量迁移 11.4. 在mysql端进行DDL和DML
mysql 端进行了5个事务

在mysql端进行增删改和DDL

You are now connected to database world4 as user omm.

UPDATE 1

PG建表无法同步到mysql但是继续在PG继续进行DML原有表的数据依然能同步到mysql
