Aerospike's Cross-Datacenter Replication (XDR) is a highly flexible feature that enables real-time active-active data replication between geographically separated clusters, eliminating dependency between sensor data collection points and analysis points. XDR makes data management simple by allowing dynamic addition and configuration of new data centers, record shipping based on Last Update Time, and facilitating data transfer to non-Aerospike data repositories. It is efficient due to fine-grain data control with selective shipment of record components, low latency execution with ultra-low latency operation, and bi-directional filtering capability that saves network costs and enables compliance with global and local data privacy regulatory requirements. XDR also offers proxy and rewind features for configuration in containerized/cloud environments and reliable disaster management. The feature is critical to mission-critical IoT use cases such as autonomous vehicles/drone/ship and Federal/DoD segments, enabling insight generation at the core from real-time data collected at the edge and pushing back that insight to trigger an immediate response. XDR can be deployed over satellite communication links with latency of ~600 milliseconds, making it suitable for scenarios like a cruise ship in the middle of the ocean without terrestrial network connectivity.
