One of the most viewed posts we’ve written about here is our post on MapReduce from a little while ago, so when picking out the next paper to look over, I thought something related to it would be optimal. With that in mind, Yahoo! Research has a relatively new paper that they published in SIGMOD ’08, titled Pig Latin: A Not-So-Foreign Language for Data Processing. Pig Latin bills itself as a natural progression of MapReduce in several ways, and indeed looks pretty interesting.

Dynamo is built to be highly available, and sacrifices the traditional notion of consistency in order to do so.
Yet the paper itself perhaps gives a better one-liner:
Dynamo can be characterized as a zero-hop DHT, where each node maintains enough routing information locally to route a request to the appropriate node directly.
