MQ Pub/Sub: Topic host routing clusters

White paper


MQ Topic Host Routing Clusters were introduced in MQ 8.0 as an alternative for the potentially, large performance impact of direct routing.
Messages published on one queue manager are sent to another queue manager that hosts a definition of the administered topic object (this is called a “topic host queue manager”).
That topic host queue manager routes the message on to every subscription on any other queue manager in the cluster.
