Big data sets are generally huge – measuring tens of terabytes – and sometimes crossing the threshold of petabytes. It is surprising to know how much data is generated every minute. quintillion bytes of data are created every single day, and it’s only going to grow from there. As estimated by DOMO : Over 2.5

Spark follows a general execution model that helps in in-memory computing and optimization of arbitrary operator graphs, so querying data becomes much faster than disk-based engines like MapReduce. With Apache Spark, you can write collection-oriented algorithms using Scala's functional programming language.
