Overview
Explore data validation techniques for large-scale data pipelines in this 22-minute Databricks conference talk. Learn about the importance of data validation in interconnected data pipelines and compare popular frameworks like Great Expectations with lightweight alternatives. Discover how to extend Pandas-based validation libraries to Spark workflows using Fugue, an open-source framework. Gain insights into applying different validation rules for each partition in big data scenarios, addressing a common deficiency in current frameworks. Follow along with an interactive demo that combines Fugue and Pandera to create a flexible and efficient data validation solution for Spark. Understand the trade-offs between robust features and performance, and learn how to tailor your validation approach to your specific needs.
