Evaluating data quality with Amazon Glue Studio

Amazon Glue Data Quality evaluates and monitors the quality of your data based on rules that you define. This makes it easy to identify the data that needs action. In Amazon Glue Studio, you can add data quality nodes to your visual job to create data quality rules on tables in your Data Catalog. You can then monitor and evaluate changes to your datasets as they evolve over time. For an overview of how to work with Amazon Glue Data Quality in Amazon Glue Studio, see the following video.
