Unity Managed Routing can enforce data consistency across multiple Teradata systems operating asynchronously in parallel. This provides true active-active availability. Each Teradata system can run the same request in parallel, providing faster response times and zero RTO (Recovery Time Objective) and RPO (Recovery Point Objective), so that if a system fails the other systems are already up-to-date and ready to continue processing requests.

The tables written to use Managed Routing must be consistent, with the same data and table definition on all systems.
