Map Reduce implemented over HTTP

I'm glad to see this is not a SOAP opera and has no XML b.s. of any kind in it. In fact you can see one YAML file in the sources.<p>Jeff Atwood knew something probably... <a href="http://www.codinghorror.com/blog/archives/001114.html" rel="nofollow">http://www.codinghorror.com/blog/archives/001114.html</a>

I've been playing with GridGain lately. It's Java, but their API is really sweet. You basically implement a simple interface that defines the map/reduce operations and then your code will be copied to the cluster nodes through a peer-to-peer classloader.<p>In a recent test I validated a million image urls in less than a minute. In a small EC2 cluster running GridGain.<p>It's certainly worth looking into if you are interested in that kind of stuff.<p><a href="http://www.gridgain.org" rel="nofollow">http://www.gridgain.org</a>

It's a shame there are no comments to this yet. If you're relatively new to programming (say, a college student), this is a really cool chunk of code to copy into notepad and figure out.<p>It really shows you how a tiny amount of code can do some pretty cool stuff.

Built for Google App Engine? I think it will kill your request if handling it takes more than 8 seconds. Not useful yet.

Doesn't CouchDB already do this in some way?
