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

问题描述

我最近阅读了这篇精彩的文章，它简洁地解释了 Google 的 MapReduce 的强大功能:

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

在 Mastering Delphi 2009 中，Marco Cantu 展示了一个使用匿名函数的多线程 for 循环，这基本上是 MapReduce 的 Map 部分，但表示它不完整并且还有其他示例.我也隐约知道 Embarcadero 有人在开发 DTL 库，但我最近没有看到太多关于它的内容.

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，在 Delphi 中是否有可靠的 MapReduce 实现可供使用?

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

我知道 Andreas Hausladen 提供了这个方便的库，如果没有通用的 Map Reduce，这是最好的构建库吗?

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(开始 here) 关于高阶函数，尤其是 map 和 fold/reduce.虽然不是在 Delphi 中可供使用的 MapReduce 的可靠实现"，但它无疑是您自己实现 MapReduce 的一个好起点！

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!
