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.

Chapter 6: Building a 311 Data Pipeline

In the previous three chapters, you learned how to use Python, Airflow, and NiFi to build data pipelines. In this chapter, you will use those skills to create a pipeline that connects to SeeClickFix and downloads all the issues for a city, and then loads it in Elasticsearch. I am currently running this pipeline every 8 hours. I use this pipeline as a source of open source intelligence – using it to monitor quality of life issues in neighborhoods, as well as reports of abandoned vehicles, graffiti, and needles. Also, it's really interesting to see what kinds of things people complain to their city about – during the COVID-19 pandemic, my city has seen several reports of people not social distancing at clubs.

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

  • Building the data pipeline
  • Building a Kibana dashboard
