Implement dbt data quality checks with dbt-expectations
Blog post from Datadog
dbt-expectations is an open-source package developed by Datadog that enhances dbt's core testing capabilities by introducing more sophisticated data quality checks to address common issues such as complex data validation, time series data quality, statistical validation, and cross-column validation. It is widely adopted by organizations to ensure data integrity and scalability by enabling Great Expectations-style assertions that go beyond dbt's native tests. The package allows users to implement comprehensive checks directly within their dbt models, providing an early warning system to prevent data processing errors that could compromise analysis. dbt-expectations supports integration with CI/CD pipelines, allowing continuous monitoring and testing to catch regressions before they cause issues in data quality. By focusing on business-critical data points and mapping tests to clear actions, users can effectively manage alert fatigue and ensure that alerts are actionable. The package is designed to work seamlessly within existing workflows, empowering data teams to maintain healthy and reliable data pipelines.
