Delphi有MapReduce库吗？ [英] Is there a MapReduce library for Delphi?

问题描述

我最近阅读了这篇伟大的文章，其中简要说明了Google MapReduce的功能：

I recently read this great article which succinctly explains the power of Google's MapReduce:

在掌握Delphi 2009中，Marco Cantu使用匿名函数显示了一个多线程for循环，这基本上是MapReduce的Map部分，但表示它还不完整，还有其他示例。我也很模糊地意识到Embarcadero的人在DTL图书馆工作，但我最近没有看到太多。

In Mastering Delphi 2009, Marco Cantu shows a multi-threaded for loop using Anonymous functions, which is basically the Map part of MapReduce, but said it wasn't complete and there were other samples out there. I'm also vaguely aware of someone at Embarcadero working on a DTL library but I haven't seen much on it lately.

那么，MapReduce在Delphi可供使用？

So, are there solid implementations of MapReduce in Delphi available for use?

我知道Andreas Hausladen的这个方便的图书馆，如果没有一般的地图缩图，这是最好的图书馆吗？

I'm aware of this handy library from Andreas Hausladen, if there's no general Map Reduce, is this the best library to build off of?

推荐答案

Craig Stuntz在他的博客上写了一系列帖子（从 here 开始）更高级的功能，特别是映射和折叠/缩小。虽然并不是Delphi可用的MapReduce的可靠实现，但实现自己的时候肯定是一个很好的开始！

Craig Stuntz wrote a series of posts on his blog (starting here) on higher order functions, and map and fold/reduce in particular. While not a "solid implementation of MapReduce in Delphi available for use", it's certainly a good place to start when implementing your own!
