Amazon Keyspaces adds CDC iterator position for stream optimization
Amazon Keyspaces now returns a CDC iterator position in GetRecords responses, indicating if the stream tip has been reached. This feature helps optimize resource usage and reduce CDC consumption costs by allowing consumers to dynamically adjust polling frequency. The change is available in all supported AWS Regions and requires updating the AWS SDK.
