StreamSpecificationProperty Struct
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
ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_dynamodb as dynamodb } from 'aws-cdk-lib';
const streamSpecificationProperty: dynamodb.CfnGlobalTable.StreamSpecificationProperty = {
streamViewType: 'streamViewType',
};

KEYS_ONLY- Only the key attributes of the modified item are written to the stream.NEW_IMAGE- The entire item, as it appears after it was modified, is written to the stream.OLD_IMAGE- The entire item, as it appeared before it was modified, is written to the stream.NEW_AND_OLD_IMAGES- Both the new and the old item images of the item are written to the stream.
