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.

Setting up the schedule_interval parameter

One of the most widely used parameters in Airflow DAG scheduler configuration is schedule_interval. Together with start_date, it creates a dynamic and continuous trigger for the pipeline. However, there are some small details we need to pay attention to when setting schedule_interval.

This recipe will cover different forms to set up the schedule_interval parameter. We will also explore a practical example to see how the scheduling window works in Airflow, making it more straightforward to manage pipeline executions.

Getting ready

While this exercise does not require any technical preparation, it is recommended to take notes about when the pipeline is supposed to start and the interval between each trigger.

How to do it…

Here, we will show only the default_args dictionary to avoid code redundancy. However, you can always check out the complete code in the GitHub repository: https://github.com/PacktPublishing/Data-Ingestion...
