Description Gordon Sim 2008-08-15 12:17:43 UTC

+++ This bug was initially created as a clone of Bug #452141 +++

In the simplest case we should just issue session exceptions when client attempt
to do things that would push the broker above a given limit.

Moving target to 1.1 as we don't yet have a good solution for this.

--- Additional comment from gsim on 2008-07-17 11:13:49 EDT ---

Initial suggested solution is as follows:

On startup broker determines the available system memory. The default policy on
any queue for which an explicit policy is not set is to not go above a certain
percentage of this (else flow to disk or throw exception as usual).

Fixed by r679462.

--- Additional comment from gsim on 2008-08-15 04:03:45 EDT ---

Fix involves applying a fixed size (but configurable) default policy for queues (--default-queue-policy). Once the total message data on the queue reaches that limit, further publications will be either flushed to disk (if the queue is durable) or failed.

Comment 2 Frantisek Reznicek 2008-09-10 08:26:16 UTC

RHTS test MRG_Messaging/qpid_queue_policy_bz452141_bz456667 proves that queue policies (queue max message count and queue byte size) are implemented and tested. (ON_QA->VERIFIED)
