Configuring temporary message storage

Many of the pattern implementation need to store MessageExchanges temporarily. An example: the aggregator will need to keep track of the MessageExchange it is aggregating. By default, the EIPs use a plain MemoryStoreFactory to create in-memory stores, but there are other options. If you set the timeout property on the MemoryStoreFactory, it will evict old object from the in-memory store to avoid a memory leak. You can also use a JDBCStoreFactory to store data in a database instead of in memory.

Example: to use an in-memory store with timeout for a storing active and closed aggregations in a <split-aggregator/>, you can do

<eip:split-aggregator service="test:aggregator" endpoint="endpoint"
                      storeFactory="#StoreFactory" closedAggregateStoreFactory="#StoreFactory">
  <eip:target>
    <eip:exchange-target service="test:trace5" />
  </eip:target>
</eip:split-aggregator>

<bean id="StoreFactory" class="org.apache.servicemix.store.MemoryStoreFactory">
  <property name="timeout" value="120000"/> <!-- 2 minute timeout -->
</bean>
