Maybe the last time you heard the word “parallel,” before all the Hadoop MapReduce ballyhoo, was in geometry classes at school. Nowadays, however, the word seems to pepper a good deal of tech talk. Remember when the words “scale out” suddenly became a feature of all new database products? That was a parallelism thing. And if you investigate it, you’ll find it was pre-Hadoop. It all began in earnest when x86 CPUs began having multiple cores in 2004.
Esteemed analyst Robin Bloor describes his group’s view of the whole IT industry, which “willy-nilly is now going parallel”, and includes SQLstream as one of the top 10 products exploiting parallelism.
