Chapter 1. Understanding Spark

Apache Spark is a powerful open source processing engine originally developed by Matei Zaharia as a part of his PhD thesis while at UC Berkeley. The first version of Spark was released in 2012. Since then, in 2013, Zaharia co-founded and has become the CTO at Databricks; he also holds a professor position at Stanford, coming from MIT. At the same time, the Spark codebase was donated to the Apache Software Foundation and has become its flagship project.

Apache Spark is fast, easy to use framework, that allows you to solve a wide variety of complex data problems whether semi-structured, structured, streaming, and/or machine learning / data sciences. It also has become one of the largest open source communities in big data with more than 1,000 contributors from 250+ organizations and with 300,000+ Spark Meetup community members in more than 570+ locations worldwide.

In this chapter, we will provide a primer to understanding Apache Spark. We will explain the concepts behind Spark Jobs and APIs, introduce the Spark 2.0 architecture, and explore the features of Spark 2.0.

The topics covered are:

What is Apache Spark?
Spark Jobs and APIs
Review of Resilient Distributed Datasets (RDDs), DataFrames, and Datasets
Review of Catalyst Optimizer and Project Tungsten
Review of the Spark 2.0 architecture

Tomasz Drabas is a Data Scientist working for Microsoft and currently residing in the Seattle area. He has over 12 years' international experience in data analytics and data science in numerous fields: advanced technology, airlines, telecommunications, finance, and consulting. Tomasz started his career in 2003 with LOT Polish Airlines in Warsaw, Poland while finishing his Master's degree in strategy management. In 2007, he moved to Sydney to pursue a doctoral degree in operations research at the University of New South Wales, School of Aviation; his research crossed boundaries between discrete choice modeling and airline operations research. During his time in Sydney, he worked as a Data Analyst for Beyond Analysis Australia and as a Senior Data Analyst/Data Scientist for Vodafone Hutchison Australia among others. He has also published scientific papers, attended international conferences, and served as a reviewer for scientific journals. In 2015 he relocated to Seattle to begin his work for Microsoft. While there, he has worked on numerous projects involving solving problems in high-dimensional feature space.
