Strata 2012 Million Monkeys
The document discusses randomness and the infinite monkey theorem through three key points: 1) With enough random combinations, even unlikely events become probable, like monkeys randomly typing Shakespeare. 2) Hadoop has near-linear scalability, allowing computational power and storage to increase predictably by simply adding more nodes, unlike relational databases. 3) This scalability provides business value by enabling applications to expand without massive engineering efforts or code rewrites.

Editor's Notes
- #3 Interesting statistical question. Thought about since Aristotle.Randomness+Resouces+Time=AnythingPossibleNo real monkeys – need virtual monkeys
- #4 Lucky monkeyThe monkey wears a lot of hats. He generates and then compares.Every work of Shakespeare created. First was A Lover’s Complaint and last was Taming of the ShrewVisualization to find your favorite line from Shakespeare
- #5 Shakespeare lazy. Heavily influenced English Literature.Big Data isn’t always a huge file. It can be high computation.
- #6 Creating Shakespeare not a business. Don’t have Shakespeare in your data.If you look hard enough you will find itHumans are not randomYou want to be looking for what’s actually there. Check your assumptionsOperate with scientific method. Form a hypothesis. Test hypothesis against data.Offer what customers are looking for. Not what you think or favorite or new product. Only what your data shows.
- #7 This is not a map of MT and ID1 to 20 node testingKeep efficiency up RDBMS efficiency in gutter
- #8 Engineers not spending time coding to scale. Busy adding new features.No code changes for scaling. Took 1.5 months on one computer and 3.5 days on 20 nodesSpending on new computers gives a consistent, linear increase. Compare spending on RDBMS and Hadoop.
- #10 We like to ask bigger questions.I asked if Shakespeare could be randomly recreated by a bunch of virtual monkeys? The answer is yes.
