本文主要是介绍Mysql 基于 Amoeba 的 水平和垂直 分片（下），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
验证事务管理
使用程序验证。
1. 验证没有分片的表的事务操作（无回滚）。
程序片段：
Java代码
package prx.dao;
import java.util.List;
import java.util.Map;
import prx.core.string.StringUtil;
import prx.dao.core.IPrxDao;
import prx.dao.core.impl.MySqlDao;
public class Test {
public static void main(String[] args) throws Exception {
IPrxDao dao = new MySqlDao();
//开启事务，插入几条数据
dao.startTransaction();
for(int i=3; i<10; i++) {
dao.executeUpdate("insert into t_message(message_id, message_content, user_id) values(?, ?, ?)", new Object[]{i, "c" + i, i});
}
dao.commitTransaction();
//查看结果
List<Map<String, Object>> list = dao.queryForMapList("select * from t_message", new Object[]{});
for(Map<String, Object> map : list) {
System.out.println(StringUtil.valueOfMap(map));
}
}
}
执行结果：
Cmd代码

//开启事务，插入几条数据
dao.startTransaction();
for(int i=3; i<10; i++) {
dao.executeUpdate("insert into t_attention(attention_id, user_id, blog_id) values(?, ?, ?)", new Object[]{i, i, i});
}
//主键冲突，出错，回滚。
//dao.executeUpdate("insert into t_user(user_id) values(?)", new Object[]{1});
dao.commitTransaction();
//查看结果
List<Map<String, Object>> list = dao.queryForMapList("select * from t_attention", new Object[]{});
for(Map<String, Object> map : list) {

结果：
user_id 为偶数的部分都没有插入数据，回滚成功。 user_id 为偶数 分片到 server1 为主数据库
user_id 为奇数的部分都已经插入数据，回滚失败。 user_id 为奇数 分片到 server2
综上： 所有分片的表，都不能支持事务。
验证存储过程
这个就不写验证过程了。 直接写结果好了。
结果：
1. 只可以调用 server1 主数据库 的 procedure , 不能调用 server2 的。
2. server1 的 procedure 只能操作 server1 中的表， 不支持水平和垂直分片。水平切分的 t_user， 不管 user_id 奇偶 均插入到 server1。垂直切分的t_attention 表不能访问。
这篇关于Mysql 基于 Amoeba 的 水平和垂直 分片（下）的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
