Quickly detect, troubleshoot, and prevent a wide range of data issues through data observability, a set of best practices that enables data teams to gain greater visibility of data and its usage. If you're a data engineer, data architect, or Machine Learning engineer who depends on the quality of your data, this book shows you how to focus on the practical aspects of introducing data observability in your everyday work. Author Andy Petrella helps you build the right habits to identify and solve data issues, such as data drifts and poor quality, so you can stop their propagation in data applications, pipelines, and analytics. You'll learn ways to introduce data observability, including setting up a framework for generating and collecting all the information you need. Fundamentals of Data Observability is not just for data engineers or data scientists, but for anyone who interacts with data systems in their daily work life. Whether you’re a chief data officer (CDO), a chief technology officer (CTO), a manager, a leader, a developer, a data analyst, or a business manager, understanding data observability concepts and principles will empower you to make better decisions, build more robust systems, and gain greater insight from your data resources.
