As such, each article in the series is intended as a 10 minute tutorial on a particular Apache Spark topic. Apache Spark is a powerful open-source processing engine built around speed, ease of use, and sophisticated analytics. It has originally been developed at UC Berkeley in 2009, while Databricks was founded later by the creators of Spark in 2013. The Spark engine runs in a variety of environments, from cloud services to Hadoop or Mesos clusters.
