Get to grips with processing large volumes of data and presenting it as engaging, interactive insights using Spark and Python.
Get a hands-on, fast-paced introduction to the Python data science stack
Explore ways to create useful metrics and statistics from large datasets
Create detailed analysis reports with real-world data
Processing big data in real time is challenging due to scalability, information inconsistency, and fault tolerance. Big Data Analysis with Python teaches you how to use tools that can control this data avalanche for you. With this book, you’ll learn practical techniques to aggregate data into useful dimensions for posterior analysis, extract statistical measurements, and transform datasets into features for other systems.
The book begins with an introduction to data manipulation in Python using pandas. You’ll then get familiar with statistical analysis and plotting techniques. With multiple hands-on activities in store, you’ll be able to analyze data that is distributed on several computers by using Dask. As you progress, you’ll study how to aggregate data for plots when the entire data cannot be accommodated in memory. You’ll also explore Hadoop (HDFS and YARN), which will help you tackle larger datasets. The book also covers Spark and explains how it interacts with other tools.
By the end of this book, you’ll be able to bootstrap your own Python environment, process large files, and manipulate data to generate statistics, metrics, and graphs.
