商品与店铺信息进行了垂直分库，分为了 PRODUCT_DB(商品库)和STORE_DB(店铺库)
商品信息进行了垂直分表，分为了商品基本信息（t_product）和商品描述信息(t_product_desc)
考虑到商品信息的数据增长
对PRODUCT_DB(商品库)进行了水平分库，分片键使用店铺id，分片策略为 店铺id%2+1。
因此商品描述信息对所有店铺id进行了冗余。
对商品基本信息(t_product)和商品描述信息(t_product_desc)进行了水平分表，分片键使用商品id，分片策略为 商品id%2+1。并将这两张表设置为绑定表，避免笛卡尔积join.
为避免主键冲突，id生成策略采用雪花算法来生成全局唯一id.
区域信息
要求读写分离提升性能
首先启动容器
cd docker
docker-compose up -d
然后配置从库s0,s1,s2 先看 m0 状态
C:\Users\wz589>mysql -h 127.0.0.1 -P3306 -u root -p
Enter password: ******
mysql> show master status;
+-----------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+-----------------------+----------+--------------+------------------+-------------------+
| test-mysql-bin.000003 | 154 | | mysql | |
+-----------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
配置s0
C:\Users\wz589>mysql -h 127.0.0.1 -P3307 -u root -p
Enter password: ******
mysql> change master to master_host='m0', master_user='slave', master_password='123456', master_port=3306, master_log_file='test-mysql-bin.000003', master_log_pos=154, master_connect_retry=30;
Query OK, 0 rows affected, 1 warning (0.06 sec)
mysql> start slave;

mysql> show slave status \G;

与 s0配置方式类似，配置s1,s2
s1
change master to master_host='m1', master_user='slave', master_password='123456', master_port=3306, master_log_file='test-mysql-bin.000003', master_log_pos=154, master_connect_retry=30;
s2
change master to master_host='m2', master_user='slave', master_password='123456', master_port=3306, master_log_file='test-mysql-bin.000003', master_log_pos=154, master_connect_retry=30;
接下来，可以跑 test 目录下的测试用例了
