6SN1118-0DM23-0AA0

6SN1118-0DM23-0AA0采用第三方工具pt-online-schema-change。该工具可以直接进行修改，其操作原理是：首先对表加锁(表此时只读)，然后复制原表物理结构创建一个中间表，接下来修改中间表的物理结构，随后把原表数据导入中间表中，数据同步完后，锁定中间表，并删除原表，接下来rename中间表为原表，后刷新数据字典并释放锁。该工具修改过程中所修改的表有主键，且不能是联合主键。同时也存在的风险，该工具在做change修改的时候不会提示错误，但是结果会发现数据会有部分丢失。在性能方面也有的瓶颈：如在并发比较高的情况下会对业务的访问速度有影响。
