Aerospike's Cross Datacenter Replication (XDR) is a highly flexible and efficient feature that enables real-time active-active data replication between geographically separated clusters. In the context of IoT data management, XDR can eliminate dependency between sensor data collection points and data analysis points by allowing dynamic data center addition and configuration. Key features include ease of setup and use, bi-directional filtering capability, and ultra-low latency operation. XDR is particularly useful for mission-critical IoT use cases such as autonomous vehicles, drones, ships, and Federal/DoD segments. It enables real-time data collection at the edge and analysis at the core while maintaining low network costs and high data integrity.
