Interesting statistical question. Thought about since Aristotle.Randomness+Resouces+Time=Anything PossibleNo real monkeys – need virtual monkeys
Shakespeare lazy. Heavily influenced English Literature.Big Data isn’t always a huge file. It can be high computation.
This is not a map of MT and ID1 to 20 node testingKeep efficiency up RDBMS efficiency in gutter
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.
