The NoSQL movement launched officially in 1999 but rose to prominence much later perhaps closer to 2008 when Hadoop and other key value pair technologies became en vogue. Today, it’s hard to argue with the success of the movement. Large banks, insurance companies, biotech companies and dotcoms rely on NoSQL to power their services and inform their most important decisions. I first saw MapReduce at Google. I’ll never forget the conversation I shared with a search engineer who described MapReduce.
