Issue

QPID has some curious semantics on its persistent queues, namely the queue is both persisted and held in memory. i.e. the whole queue must fit into memory. There is a semi-work around which is to spool off the payload to disk by setting the qpid-policy.type to flow to disk. We desperately need an option that fully spools to disk (i.e. both payload and headers) so that nothing, other than perhaps a buffer at QPID’s discretion is held in memory.
