S3 Metadata and Annotations Now Available in AWS GovCloud
Amazon S3 Metadata and Annotations just landed in AWS GovCloud (US-East) and AWS GovCloud (US-West), letting you tag and query your S3 objects with rich business context without maintaining separate metadata systems. Your AI agents and analytics tools can now attach up to 1 GB of JSON, XML, or YAML annotations per object, making data discovery and enrichment way faster.
