Unity routing provides access and synchronization options for a set of Teradata systems using different routing rules. A routing rule defines how a session is connected to a set of Teradata systems. Choosing appropriate routing rules for different workloads is important for achieving business goals with a Unity environment. When chosen correctly, routing rules can provide such benefits as minimizing network latency, isolating workloads to particular systems, or providing additional scale across multiple systems.
Routing rules are selected using user mappings that match incoming connections based on defined criteria. Avoid updating routing rules once they are first designed. This best practice leads to a consistent behavior and understanding of what the routing rule is set to accomplish.
