mycat--垂直分表--

将shopping库中的表分给三个节点的mysql

schema.xml部分配置

<schema name="SHOPPING" checkSQLschema="true" sqlMaxLimit="100">
    <!-- 商品表，存储在 master01 -->
    <table name="tb_goods_base" dataNode="master01" primaryKey="id"/>
    <table name="tb_goods_brand" dataNode="master01" primaryKey="id"/>
    <table name="tb_goods_cat" dataNode="master01" primaryKey="id"/>
    <table name="tb_goods_desc" dataNode="master01" primaryKey="goods_id"/>
    <table name="tb_goods_item" dataNode="master01" primaryKey="id"/>
    
    <!-- 订单表，存储在 master02 -->
    <table name="tb_order_item" dataNode="master02" primaryKey="id"/>
    <table name="tb_order_master" dataNode="master02" primaryKey="order_id"/>
    <table name="tb_order_pay_log" dataNode="master02" primaryKey="out_trade_no"/>
    
    <!-- 用户表，存储在 node01 -->
    <table name="tb_user" dataNode="node01" primaryKey="id"/>
    <table name="tb_user_address" dataNode="node01" primaryKey="id"/>
    <table name="tb_areas_provinces" dataNode="node01" primaryKey="id"/>
    <table name="tb_areas_city" dataNode="node01" primaryKey="id"/>
    <table name="tb_areas_region" dataNode="node01" primaryKey="id"/>
</schema>

<!-- 数据节点定义 -->
<dataNode name="master01" dataHost="host1" database="shopping"/>
<dataNode name="master02" dataHost="host2" database="shopping"/>
<dataNode name="node01" dataHost="host3" database="shopping"/>

设置为全局表
type=“global”

server.xml

<user name="root" password="root">
    <property name="schemas">shopping</property>
</user>

mycat中可以通过source命令导入表结构

source /xxx/xx.sql
