Apache Atlas provides data governance capabilities for your Cloudera Data Platform (CDP). Apache Atlas serves as a common metadata store that is designed to collect and store metadata, show relationships among metadata entities, and give you a place to add your own information to document business processes. Close integration of Atlas with Apache Ranger enables you to define, administer, and manage security and compliance policies consistently across all components of CDP. Atlas also provides metadata and lineage to Data Catalog to support curating data across enterprise data.
