Understanding Delta Tables Constraints

<p>Delta Lake, an open-source storage layer that brings reliability to data lakes, allows you to store and manage data in data lakes. Delta tables are a core concept of Delta Lake, which enables data versioning, transactional reads and writes, schema enforcement, and metadata management. In this article, we will focus on Delta tables constraints, how they work, and their implementation with code examples.</p> <h1>What are Delta Tables Constraints?</h1> <p>Delta tables constraints are a set of rules that control the values that are inserted, updated, or deleted in a Delta table. They help to ensure data integrity and consistency by enforcing data quality rules. Delta tables constraints come in two forms: Column constraints and Table constraints.</p> <p><a href="https://medium.com/towards-data-engineering/understanding-delta-tables-constraints-3f4a6e7caa40"><strong>Click Here</strong></a></p>
