This configuration expands on the MQTT Engine Servers - Filtered Namespaces by applying to all servers in a specific server set. If connection is switched to another server within the same server set, filtered namespaces are applied.

Example

A system with Edge devices publishing using the Sparkplug B protocol to Server A and Edge devices publishing MQTT messages to a failover server pair Server B and Server C.

In this instance the Access Control Lists (ACLs) on Servers B and C may not allow for the subscriptions required by MQTT Engine for the Sparkplug B protocol. Associating a Server Set for the Sparkplug B namespace will disable the namespace for all server connections associated with the server set.
