AWS expanded preview capabilities for Glue Data Catalog by enabling export of catalog metadata, including glossary and custom business attachments, into Apache Iceberg-format tables stored in S3. This allows for SQL-based querying over metadata for auditing and analysis using services like Amazon Athena and QuickSight, enabling richer metadata insights through combination with other AWS data.
Additionally, semantic search now supports catalogs encrypted with KMS Customer Managed Keys, extending security features without sacrificing metadata enrichment. These capabilities currently operate in select US and European AWS regions during preview, involve S3 storage costs, and have not been independently tested for performance or security beyond AWS documentation.
