Which AWS service is specifically designed for defining and enforcing data quality rules and thresholds in automated pipelines?
💡 Model Answer
AWS Glue Data Quality is the service that lets you create, manage, and enforce data quality rules within your ETL pipelines. It allows you to define checks for completeness, uniqueness, accuracy, and format, and to set thresholds that determine whether a dataset passes or fails. The service integrates directly with Glue ETL jobs, so a job can be automatically marked as failed or flagged if the data does not meet the specified quality criteria. Glue Data Quality also provides a quality score and detailed diagnostics, helping data engineers quickly identify and resolve issues. Unlike Glue Jobs, which only execute transformations, or CloudFormation, which provisions infrastructure, Glue Data Quality focuses on the correctness and reliability of the data itself.
