说完了MySQL,我们再来看看PostgreSQL(开源数据库永远的老二)是否也存在这个问题。由于我本身对PostgreSQL是不太熟的,所以查阅了相关文档后发现,PG在很早的版本就引入了full page write机制,来避免这种partial write问题。 这里我盗用一张图片来简单解释一下PostgreSQL的数据写入流程: 1、假设T1 时间点触发了checkpoint; 2...

这里我盗用一张图片来简单解释一下PostgreSQL的数据写入流程: 1、假设T1 时间点触发了checkpoint; 2、T2时间点开始将DML操作产生的变化刷到xlog(关系型数据库都是日志写优先原则); 3、T3时间点事务发起了commit提交操作;这个时候会将脏页变化落盘xlog(这时候仍然还没开始写脏页); ...

Adaptability: While it can handle standard SQL, you can also specify different flavors (e.g., MySQL, PostgreSQL) for more tailored query outputs. Disadvantages: Lacks Deep Context: While GPT-4 can process provided information, it doesn't possess a deep understanding of a specific database's ...
