How does DataHub compare to AWS Glue Data Catalog?

DataHub is an open-source metadata platform with a rich UI, push/pull ingestion from 50+ sources, programmatic metadata management via API, and data lineage visualization. Glue Data Catalog is AWS-native and tightly integrated with Athena, EMR, and Glue ETL but provides limited governance features. DataHub adds lineage, search, ownership workflows, and data contracts that Glue Catalog lacks.

When should I invest in a dedicated data catalog like Alation or Collibra?

Invest in enterprise data catalogs when your organization has hundreds of datasets across multiple systems, when data governance and regulatory compliance (GDPR, CCPA) require documented data lineage and ownership, when business users need curated, trusted data discovery, or when you have dedicated data stewards managing data quality and policies. Glue Catalog serves engineering needs; enterprise catalogs serve the whole organization.

Is Apache Atlas a viable self-hosted alternative to the Glue Data Catalog?

Atlas is viable for organizations already running Hadoop/HDP ecosystems, providing tag-based policies, lineage, and metadata classification. However, it's primarily an operational metadata system for the Hadoop ecosystem rather than a modern data catalog. DataHub, OpenMetadata, or Amundsen are more modern open-source alternatives with better UX and broader connector support beyond Hadoop.
