Description Sergei Vorobiev 2008-06-19 14:49:13 UTC
When a transient queue with transient messages reaches pre-configured maximum
size , a messaging broker process should start committing the queue to disk with
expected performance impact to new incoming messages. This is required to
prevent memory exhaustion if messages are not retrieved from the queue by a
client, while new messages continue to arrive.

We already do this for transient messages on durable queues which may be sufficient.

Comment 3 Gordon Sim 2008-10-14 16:07:53 UTC
Confirmed that flow to disk of transient (and durable) messages on durable queues is suffient here for now.
