How to Build Production-Grade Data Validation Pipelines Using Pandera, Typed Schemas, and Composable DataFrame Contracts
Schemas, and Composable DataFrame Contracts In this tutorial, we demonstrate how to build robust, production-grade data validation pipelines using Pandera with typed DataFrame models. We start by simulating realistic, imperfect transactional data and progressively enforce strict schema constraints, column-level rules, and cross-column business logic using declarative checks. We show how lazy validation helps us surface multiple data quality issues at once, how invalid records can be quarantined without breaking pipelines, and how schema enforcement can be applied directly at function boundaries to guarantee correctness as data flows through transformations.
