Big Data Analysis with Python

Overview of this book

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.

Summary


In this chapter, we have learned how to maintain code reproducibility from a data science perspective through structured standards and practices to avoid duplicate work using the Jupyter notebook.

We started by gaining an understanding of what reproducibility is and how it impacts research and data science work. We looked into areas where we can improve code reproducibility, particularly looking at how we can maintain effective coding standards in terms of data reproducibility. Following that, we looked at important coding standards and practices to avoid duplicate work using the effective management of code through the segmentation of workflows, by developing functions for all key tasks, and how we can generalize coding to create libraries and packages from a reusability standpoint.

In the next chapter, we will learn how to use all the functionalities we have learned about so far to generate a full analysis report. We will also learn how to use various PySpark functionalities for...
