             Summary: Add flow to disk queue policy
                 Key: QPID-7776
                 URL: https://issues.apache.org/jira/browse/QPID-7776
             Project: Qpid
          Issue Type: Improvement
          Components: Java Broker
            Reporter: Keith Wall
             Fix For: qpid-java-broker-7.0.0


It should be possible to configure a queue so that enqueues are always flowed 
to disk, or are flowed to disk when the queue reaches a certain length or depth.

A common use case for this would be a user who has one queue that is used 
_store and forward_ (say for an end of day batch) whilst other queues are used 
'live'.  It will make sense for such a user for to mark the batch's queue flow 
to disk.  That way the messages on the batch queue don't needlessly clog the 
Broker's memory leaving it free for intraday work.

The C++ Broker already has an analogous feature.
