AWS Lambda Enables Cross-Account DynamoDB Streams Support
🔁 AWS Lambda now supports cross-account access for DynamoDB Streams event-source mappings, enabling streams in one account to trigger Lambda functions in another. By attaching a resource-based policy to a DynamoDB stream, owners can grant functions in other accounts permission to consume change events without replicating data. The capability is generally available across AWS Commercial and AWS GovCloud (US) Regions and can be configured via the Console, CLI, SDKs, CloudFormation, or APIs. This reduces operational overhead and simplifies multi-account event-driven architectures.
