		<description>回复felix：
我个人觉得作者在这个概念上说得不是很清楚。如果没有doublewrite buffer，在直接写物理磁盘的时候，如果发生了系统崩溃，那么如果页没有损坏（这个损坏我一直没找到很好的词语来说得更形象）那么通过redo log是能恢复的，因为redo本身就是记录的页物理上的改变，而如果发生了页损坏呢？那么如果没有doublewrite buffer这个功能是不是就无法进行恢复了？或者能恢复但是一定会造成数据丢失呢？ 所以doublewrite buffer主要的功能就是防止页损坏。
不知这样理解对么？</description>

		<description>有编译错误，还需要修改代码，如下：
sql/sql_show.cc中
class thread_info :public ilink {
public:
  const char *user,*host,*db,*proc_info,*state_info;
  CSET_STRING query_string;

  /**   start  */
  ulong my_row_count;
  /* end */
};</description>

		<description>hi,你好。

如何理解“显式的定义一个 INT 类型自增字段的主键，这个字段可以仅用于做主键，不做其他用途”。

如果使用一个表的主键作为另外一张表的外键关联，这样算不算“ 有业务意义”？</description>
