Apache Spark's speed, ease of use, sophisticated analytics, and
multilanguage support makes practical knowledge of this
cluster-computing framework a required skill for data engineers and data
scientists. With this hands-on guide, anyone looking for an introduction
to Spark will learn practical algorithms and examples using PySpark.
In each chapter, author Mahmoud Parsian shows you how to solve a data
problem with a set of Spark transformations and algorithms. You'll learn
how to tackle problems involving ETL, design patterns, machine learning
algorithms, data partitioning, and genomics analysis. Each detailed
recipe includes PySpark algorithms using the PySpark driver and shell
script.
With this book, you will:
- Learn how to select Spark transformations for optimized solutions
- Explore powerful transformations and reductions including
reduceByKey(), combineByKey(), and mapPartitions()
- Understand data partitioning for optimized queries
- Build and apply a model using PySpark design patterns
- Apply motif-finding algorithms to graph data
- Analyze graph data by using the GraphFrames API
- Apply PySpark algorithms to clinical and genomics data
- Learn how to use and apply feature engineering in ML algorithms
- Understand and use practical and pragmatic data design patterns
