关于数据写入缓存设计
比如说文章的浏览数会根据每一次访问而递增，每次都写入的话影响性能，单纯memcache数据可能丢失。利用mysql，和memcache，我琢磨着每次写入读取都在memcache，mysql上建一个记录表保存需要缓存的表名及字段信息，在每隔5分钟执行计划任务，读取记录表对应着将memcache缓存持久化到mysql相应表。感觉设计的很蹩脚，大家这一类写入缓存是怎么设计的？

用redis来代替memcache就可以了，计数器都写到redis里面去
<code>if($memcache->inc()/100 == 0){
$mysql->write();
}
</code>
