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.
Table of Contents (21 chapters)
Section 1: Building Data Pipelines – Extract Transform, and Load
Section 2:Deploying Data Pipelines in Production
Section 3:Beyond Batch – Building Real-Time Data Pipelines

Chapter 9: Monitoring Data Pipelines

You now know how to build data pipelines that are production ready—they are idempotent, use atomic transactions, and are version controlled. They are ready to start running in production, but before you can deploy them, you need to be able to monitor them. There will be errors in the code, in the data, in the network, or in other areas outside your control. You will need to know when errors happen, and when things are running as they should.

In this chapter, we're going to cover the following main topics:

  • Monitoring NiFi in the GUI
  • Monitoring NiFi using processors
  • Monitoring NiFi with Python and the REST API
