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.
Example
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { mixins as dynamodb_mixins } from '@aws-cdk/mixins-preview/aws-dynamodb';
const streamSpecificationProperty: dynamodb_mixins.CfnGlobalTablePropsMixin.StreamSpecificationProperty = {
streamViewType: 'streamViewType',
