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.

Monitoring our data ingest file size

When ingesting data, we can track a few items to ensure the incoming information is what we expect. One of the most important of these items is the data size we are ingesting, which can mean file size or the size of chunks of streaming data.

Logging the size of incoming data allows the creation of intelligent and efficient monitoring. If at some point the size of incoming data diverges from what is expected, we can take action to investigate and resolve the issue.

In this recipe, we will create simple Python code that logs the size of ingested files, which is very valuable in data monitoring.

Getting ready

We will use only Python code. Make sure you have Python version 3.7 or above. You can use the following command on your CLI to check your version:

$ python3 –-version
Python 3.8.10

The following code execution can be done using a Python shell or a Jupyter notebook.
