3 ZagadeCover WorkShantanu N. the AuthorAmit Nandi studied physics at the Free University of Brussels in Belgium, where he did his research on computer generated holograms. Computer generated holograms are the key components of an optical computer, which is powered by photons running at the speed of light. He then worked with the university Cray supercomputer, sending batch jobs of programs written in Fortran. This gave him a taste for computing, which kept growing. He has worked extensively on large business reengineering initiatives, using SAP as the main enabler. He focused for the last 15 years on start-ups in the data space, pioneering new areas of the information technology landscape.

4 He is currently focusing on large-scale data-intensive applications as an enterprise architect, data engineer, and software developer. He understands and speaks seven human languages. Although Python is his computer language of choice, he aims to be able to write fluently in seven computer languages want to express my profound gratitude to my parents for their unconditional love and strong support in all my book arose from an initial discussion with Richard Gall, an acquisition editor at Packt Publishing. Without this initial discussion, this book would never have happened. So, I am grateful to him. The follow ups on discussions and the contractual terms were agreed with Rebecca Youe.

5 I would like to thank her for her support. I would also like to thank Merint Mathew, a content editor who helped me bring this book to the finish line. I am thankful to Merint for his subtle persistence and tactful support during the write ups and revisions of this are standing on the shoulders of giants. I want to acknowledge some of the giants who helped me shape my thinking. I want to recognize the beauty, elegance, and power of Python as envisioned by Guido van Rossum. My respectful gratitude goes to Matei Zaharia and the team at Berkeley AMP Lab and Databricks for developing a new approach to computing with Spark and Mesos. Travis Oliphant, Peter Wang, and the team at are doing a tremendous job of keeping Python relevant in a fast-changing computing landscape.

6 Thank you to you the ReviewersManuel Ignacio Franco Galeano is a software developer from Colombia. He holds a computer science degree from the University of Quind o. At the moment of publication of this book, he was studying to get his MSc in computer science from University College Dublin, Ireland. He has a wide range of interests that include distributed systems, machine learning, micro services, and so on. He is looking for a way to apply machine learning techniques to audio data in order to help people learn more about Kavale works as a software developer at TinyOwl Ltd. He is interested in multiple technologies ranging from building web applications to solving big data problems.

7 He has worked in multiple languages, including Scala, Ruby, and Java, and has worked on Apache Spark, Apache Storm, Apache Kafka, Hadoop, and Hive. He enjoys writing Scala. Functional programming and distributed computing are his areas of interest. He has been using Spark since its early stage for varying use cases. He has also helped with the review for the Pragmatic Scala Lemire has a BSc and MSc in mathematics from the University of Toronto and a PhD in engineering mathematics from the Ecole Polytechnique and the Universit de Montr al. He is a professor of computer science at the Universit du Qu bec. He has also been a research officer at the National Research Council of Canada and an entrepreneur.

8 He has written over 45 peer-reviewed publications, including more than 25 journal articles. He has held competitive research grants for the last 15 years. He has been an expert on several committees with funding agencies (NSERC and FQRNT). He has served as a program committee member on leading computer science conferences (for example, ACM CIKM, ACM WSDM, ACM SIGIR, and ACM RecSys). His open source software has been used by major corporations such as Google and Facebook. His research interests include databases, information retrieval and high-performance programming. He blogs regularly on computer science at Mancini is a data engineer at Intent Media, Inc in New York, where he works with the data science team to store and process terabytes of web travel data to build predictive models of shopper behavior.

9 He enjoys functional programming, immutable data structures, and machine learning. He writes and speaks on topics surrounding data engineering and information is a contributor to Apache Spark and other libraries in the Spark ecosystem.
