Delta Live Tables (DLT) is specifically designed for building and maintaining reliable, automated data pipelines. It includes built-in data quality enforcement through expectations and constraints, which allows data engineers to: Define Data Quality Expectations: For example, you can define constraints such as CONSTRAINT valid_values EXPECT (column_name IS NOT NULL) to automatically enforce data quality rules. Monitor Violations: DLT tracks data quality metrics and logs violations, enabling monitoring of data quality trends over time. Automated Notifications and Actions: DLT can handle violations (e.g., drop rows, fail the pipeline, or log them for review) in an automated way.
