20.10.4. Using Duplicate Detection with Bridges and Cluster Connections

Core bridges can be configured to automatically add a unique duplicate ID value (if there isn't already one in the message) before forwarding the message to the target. To configure a core bridge for duplication message detection set the property use-duplicate-detection to "true" in server configuration files (standalone.xml and domain.xml). The default value of this parameter is "true".
Cluster connections internally use core bridges to move messages between nodes of the cluster. To configure a cluster connection for duplicate message detection set the property use-duplicate-detection to "true" in server configuration files (standalone.xml and domain.xml). The default value of this parameter is "true".
