Swoole一键操作基于阿里云的RDS数据库迁移+OSS文件搬迁
传统的数据库搬迁思路是把数据库表的结构及数据都查询出来，然后通过循环进行数据结构重组拼接。然后导出！数据量少的话，这样当然是没毛病。当数据量太大的时候，服务器的内存开销就吃不住了，很容易炸掉，导致服务器瘫掉。当然我之前也这么干的 ，所以也一直想办法解决这个问题 ，当你体会到大数据搬迁的那酸爽、提心吊胆你就明白了
一天我看到一条sql
SELECT COUNT( * ) as cnt FROM information_schema.TABLES WHERE TABLE_SCHEMA = 旧数据库名
CREATE TABLE IF NOT EXISTS 新数据库名.表名 LIKE 旧数据库名.表名
INSERT 新数据库名.表名 SELECT * FROM 旧数据库名.表名
相信看到这几条sql 就应该有思路了，没错就是这三条sql!
废话不说了 上代码
