Data Engineering with Python

By: Paul Crickard

Overview of this book

Data engineering provides the foundation for data science and analytics, and forms an important part of all businesses. This book will help you to explore various tools and methods that are used for understanding the data engineering process using Python. The book will show you how to tackle challenges commonly faced in different aspects of data engineering. You’ll start with an introduction to the basics of data engineering, along with the technologies and frameworks required to build data pipelines to work with large datasets. You’ll learn how to transform and clean data and perform analytics to get the most out of your data. As you advance, you'll discover how to work with big data of varying complexity and production databases, and build data pipelines. Using real-world examples, you’ll build architectures on which you’ll learn how to deploy data pipelines. By the end of this Python book, you’ll have gained a clear understanding of data modeling techniques, and will be able to confidently build data engineering pipelines for tracking data, running quality checks, and making necessary changes in production.

Versioning your data pipelines

You can use the NiFi Registry to version your data pipelines inside of a processor group. I have NiFi running and the canvas zoomed in to the SeeClickFix processor group from Chapter 6, Building a 311 Data Pipeline. To start versioning this data pipeline, right-click on the title bar of the processor group and select Version | Start version control, as shown in the following screenshot:

Figure 8.8 – Starting version control on a processor group

Your processor group is now being tracked by version control. You will see a green checkmark on the left of the processor group title box, as shown in the following screenshot:

If you browse back to the NiFi Registry, you will see that Scf-DataEngineeringPython is being tracked. You will also see the details by expanding the bar. The details show your description and the version notes (First Commit...
