feature

Amazon DynamoDB Streams now supports Attribute-Based Access Control (ABAC), allowing tag-based conditions in IAM policies to manage data stream access. This simplifies access management for teams needing to enforce different access levels across multiple applications and environments with fewer IAM policies. Users can attach up to 50 tags per stream, which are managed independently from their parent table tags, providing flexible isolation and compliance. The feature is available in all commercial and AWS GovCloud (US) Regions where DynamoDB Streams are present, at no additional cost.
