Amazon Keyspaces now returns an iterator position in CDC stream responses, showing whether the consumer is at the tip or behind the latest records. This allows clients to adjust polling frequency dynamically, reducing unnecessary calls and cutting CDC consumption costs while keeping data processing timely.
Previously, consumers polled CDC streams at fixed intervals regardless of new data availability, leading to inefficiencies. The iterator position feature is available across supported AWS regions for Keyspaces CDC, requiring SDK updates for adoption and enabling more resource-effective event-driven architectures and analytics integrations.
