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.

Using notification operators

So far, we have focused on ensuring that code is well logged and has enough information to provide valid monitoring. Nevertheless, the purpose of having mature and structured pipelines is to avoid the necessity of manual intervention. With busy agendas and other projects, it is hard to constantly look at monitoring dashboards to check whether everything is fine.

Thankfully, Airflow also has native operators to trigger alerts depending on their configured situation. In this recipe, we will configure an email operator to trigger a message every time a pipeline succeeds or fails, allowing us to remediate the problem rapidly.
