垂直分库实际上就是进行多表分库管理

1.分别在多台MySQL主机上进行多个表的创建

2.schema.xml

<mycat:schema xmlns:mycat="http://io.mycat/">
        <schema name="TESTDB1" checkSQLschema="false" sqlMaxLimit="100" dataNode="dn1"/>
        <schema name="TESTDB2" checkSQLschema="false" sqlMaxLimit="100" dataNode="dn2"/>
        <dataNode name="dn1" dataHost="localhost1" database="db1" />
        <dataNode name="dn2" dataHost="localhost2" database="db2" />
        <dataHost name="localhost1" maxCon="1000" minCon="10" balance="2"
                          writeType="0" dbType="mysql" dbDriver="native" switchType="1"  slaveThreshold="100">
                <heartbeat>select user()</heartbeat>
                <writeHost host="host1" url="192.168.1.199:3306" user="root" password="123456"/>
        </dataHost>
        <dataHost name="localhost2" maxCon="1000" minCon="10" balance="2"
                          writeType="0" dbType="mysql" dbDriver="native" switchType="1"  slaveThreshold="100">
                <heartbeat>select user()</heartbeat>
                <writeHost host="host2" url="192.168.1.166:3306" user="root" password="123456"/>
        </dataHost>
</mycat:schema>

3.server.xml

<property name="schemas">TESTDB1,TESTDB2</property>

4.重启mycat

5.此时即完成了垂直分库，数据操作时需要指定具体操作的是哪一个数据库
