HornetQ does not support database-based persistence. For reasons that went into this decision see https://developer.jboss.org/thread/153581. More details in "Messaging persistence in EAP 6.x" https://access.redhat.com/solutions/226743.

=What Does HornetQ Persist?=

==Bindings==

==JMS==

==Large Messages==

==Non Persistent Messages==

When a node is started for the first time it persists a unique identifier into its journal directory. This ID is needed for proper formation of [[#Clustering|clusters]].
