I assisted to the highly successful Montreal FinTech 2015 conference (with over 500 participants who attended) as an exhibitor, in order to promote the automated statistical induction tool Nectarine that I'm working on.
I was surprised to see how often the words Apache, Spark, Hadoop, and even Flink came up. There were about 21 exibhitors, of which only a handful were software vendors, and yet my software wasn't the only one built on top of Hadoop and Spark (in fact I'm not sure if any of the software products being presented were not built on top of these technologies!).
It's good news to see that these technologies are exploding even outside of Big Data & Data Science communities.
In the picture I'm presenting a demo of Nectarine to the Ticksmith dev team, who have built very successful Big Data Fintech software on top of Hadoop & Spark.
