MapReduce与database之争

Posted in Oracle at 5:40 下午 由 wanghai

最近IT业界比较热闹的事情是数据库的大牛David DeWitt写了一篇文章说google的mapreduce是数据库技术的一种倒退，结果google的一帮人Greg Jorgensen不干了，也写了一篇文章驳斥了David DeWitt，认为David DeWitt根本是搞不清楚状况，说是David DeWitt拿mapreduce和rdbms来对比是一件极其错误的事情，这件事情自然引得很多人来评论和关注，Greg Linden 也写了一篇blog来关注这件事情

其中有一个人有一个很有意思的评论，话有点损人，鄙视了David DeWitt乱点鸳鸯谱

Other articles I’m inspired to write based on the referenced article:

I tried using MapReduce to create a website, and it sucks compared to markup with CSS. It doesn’t have any concept of how to style a website. MapReduce is a serious step backward in terms of web design.

I also tried to have MapReduce babysit my kids, and I came back half an hour later to find that it was just sitting there crunching data, and wasn’t watching them at all. This thing can’t do anything at all.

Also, compared to a standard hammer, this MapReduce things is really crappy at pounding nails into things.

从目前来看反对David DeWitt的人占了多数，看来争论还将继续下去，从这件事情中我们也可以得到一个启发，千万不要对自己不熟悉的东西妄加评论，在对一个新事物下结论前一定要好好的了解它。
