Overview

Represents the DynamoDB Streams configuration for a table in DynamoDB .

You can only modify this value for a AWS::DynamoDB::GlobalTable resource configured for multi-Region eventual consistency (MREC, the default) if that resource contains only one entry in Replicas . You must specify a value for this property for a AWS::DynamoDB::GlobalTable resource configured for MREC with more than one entry in Replicas . For Multi-Region Strong Consistency (MRSC), Streams are not required and can be changed for existing tables.
