             Summary: [Java Broker] Store transient messages to disk (and remove from memory)
when in low memory conditions
                 Key: QPID-5965
                 URL: https://issues.apache.org/jira/browse/QPID-5965
             Project: Qpid
          Issue Type: Improvement
          Components: Java Broker
            Reporter: Rob Godfrey
            Assignee: Rob Godfrey
             Fix For: 0.29


Currently the Java Broker will evacuate persistent messages from memory in low memory situations,
but does not do the same with transient messages.  By monitoring total queue size, we can
determine when it may be appropriate to force transient messages to disk (and thus make them
eligible for evacuation from memory) and in this way make the broker capable of withstanding
periods of increased retention of transient messages.
