دانلود کتاب Learning Spark SQL

Key FeaturesLearn about the design and implementation of streaming applications, machine learning pipelines, deep learning, and large-scale graph processing applications using Spark SQL APIs and Scala.Learn data exploration, data munging, and how to process structured and semi-structured data using real-world datasets and gain hands-on exposure to the issues and challenges of working with noisy and "dirty" real-world data.Understand design considerations for scalability and performance in web-scale Spark application architectures.Book DescriptionIn the past year, Apache Spark has been increasingly adopted for the development of distributed applications. Spark SQL APIs provide an optimized interface that helps developers build such applications quickly and easily. However, designing web-scale production applications using Spark SQL APIs can be a complex task. Hence, understanding the design and implementation best practices before you start your project will help you avoid these problems.This book gives an insight into the engineering practices used to design and build real-world, Spark-based applications. The book's hands-on examples will give you the required confidence to work on any future projects you encounter in Spark SQL.It starts by familiarizing you with data exploration and data munging tasks using Spark SQL and Scala. Extensive code examples will help you understand the methods used to implement typical use-cases for various types of applications. You will get a walkthrough of the key concepts and terms that are common to streaming, machine learning, and graph applications. You will also learn how such systems are architected and deployed for a successful delivery of your project. Finally, you will move on to performance tuning, where you will learn practical tips and tricks to resolve performance issues.What you will learnFamiliarize yourself with Spark SQL programming including working with DataFrame/Dataset API and SQL.Perform a series of hands-on exercises with different types of data source including CSV, JSON, Avro, MySQL, and MongoDB.Perform data quality checks, data visualization, and basic statistical analysis tasks.Perform data munging tasks on publically available datasets.Learn to use Spark SQL and SparkR for typical data science tasks.Learn key performance-tuning tips and tricks in Spark SQL applicationsLearn to identify cases where Spark SQL can be used in large-scale application architectures.
