Data Ingestion with Python Cookbook

By: Gláucia Esppenchutz

Overview of this book

Data Ingestion with Python Cookbook offers a practical approach to designing and implementing data ingestion pipelines. It presents real-world examples with the most widely recognized open source tools on the market to answer commonly asked questions and overcome challenges. You’ll be introduced to designing and working with or without data schemas, as well as creating monitored pipelines with Airflow and data observability principles, all while following industry best practices. The book also addresses challenges associated with reading different data sources and data formats. As you progress through the book, you’ll gain a broader understanding of error logging best practices, troubleshooting techniques, data orchestration, monitoring, and storing logs for further consultation. By the end of the book, you’ll have a fully automated set that enables you to start ingesting and monitoring your data pipeline effortlessly, facilitating seamless integration with subsequent stages of the ETL process.

Putting Everything Together with Airflow

So far, we have covered the different aspects and steps of data ingestion. We have seen how to configure and ingest structured and unstructured data, what analytical data is, and how to improve logs for more insightful monitoring and error handling. Now is the time to group all this information to create something similar to a real-world project.

From now on, in the following chapters, we will use Apache Airflow, an open source platform that allows us to create, schedule, and monitor workflows. Let’s start our journey by configuring and understanding the fundamental concepts of Apache Airflow and how powerful this tool is.

In this chapter, you will learn about the following topics:

  • Configuring Airflow
  • Creating DAGs
  • Creating custom operators
  • Configuring sensors
  • Creating connectors in Airflow
  • Creating parallel ingest tasks
  • Defining ingest-dependent DAGs

By the end of this...
