Key/value is dead. Long live tuples: Pangool for Hadoop

I just popped in to say that I'm tired of the "X is dead" linkbait headlines. They demonstrate a myopic view of the world. Visual Basic and COBOL are still around.

a couple of links that came to mind with this:<p><a href="http://en.wikipedia.org/wiki/Tuple_space" rel="nofollow">http://en.wikipedia.org/wiki/Tuple_space</a><p><a href="http://en.wikipedia.org/wiki/Linda_(coordination_language)" rel="nofollow">http://en.wikipedia.org/wiki/Linda_(coordination_language)</a><p><a href="http://www.amazon.com/Mirror-Worlds-Software-Universe-Shoebox-How/dp/019507906X/ref=sr_1_1?ie=UTF8&#38;qid=1331144023&#38;sr=8-1" rel="nofollow">http://www.amazon.com/Mirror-Worlds-Software-Universe-Shoebo...</a>

I'm wondering what's the need for this when we already have Apache Pig, etc?

So it sounds like this slots in like so, in order of abstraction:<p>HIVE -&#62; Pig -&#62; Pangool -&#62; Cascading -&#62; MapReduce<p>Nice addition!

Tuples reminds me of RDBMS
