Persistence Layer

Default persistence layer

Since Fuse Message Broker 5.4.0, the KahaDB message store is the default persistence layer used by Fuse Message Broker. The KahaDB message store is the latest evolution of Fuse Message Broker's native message store and it supersedes both the AMQ message store and the (original) Kaha message store.

If no configuration is specified for the KahaDB message store, an instance with default settings is automatically created for you.

Example KahaDB message store configuration

The KahaDB message store can be configured explicitly using the kahaDB element inside the persistenceAdapter element, as follows:

<broker brokerName="broker" persistent="true" useShutdownHook="false">
  ...
  <persistenceAdapter>
    <kahaDB directory="activemq-data"/>
  </persistenceAdapter>
</broker>
