Re: [Haskell-cafe] MapReduce reverse engineered

The author(s) are from Microsoft .. they claimed to reverse engineer internals. My understanding is that MapReduce internals **is** a Google closely held secret ... hence the open source version is "dumbed down" .. I have forgotten the name.

I've read this article too, and I must say that it is indeed a very interesting and exciting read, both in terms of understanding MapReduce and its capabilities somewhat better, and in terms of beholding the beauty of Haskell.

It is not exactly reverse engineering, but it is expressing the essense of MapReduce algorithms, prerequisites, axioms, dimensions of its design space etc. in Haskell.

Vasili, What do you mean? Googles MapReduce is already a published / well understood concept so no reverse engineering is needed. If you are asking about pre-existing implementations, there is at least one [1] but only for reference, not speed. If you are asking about community interest, great and you might want to say something on the haskell proposals reddit [2].

Hello,

Here is an interesting paper of Google's MapReduce reverse engineered into Haskell. I apologize if already posted ..... http://www.cs.vu.nl/~ralf/MapReduce/http://www.cs.vu.nl/%7Eralf/MapReduce/

Kind regards, Vasili
