Yesterday I gave a talk to PittJug about Map-Reduce and a few patterns that are useful. While I plan to update
the slides with additional drawings, better examples and removed typos, I thought perhaps those in attendance would appreciate being able to see them.

This talk is meant to provide very basic introduction to map-reduce and show the power of the abstraction through a few high-level patterns. Hopefully it guides you to the important decisions you have to make when using map-reduce.
