I'm looking at the stats in qpid-tool and it showed the queue is durable. My producer client is using Async session, will this delay become noticeable when the producer is commiting thousands of messages in a few seconds? And could we have any memory problems when this rejection happened? I'm trying to rule out the possibility that a full queue will cause performance issue to the producer which is busy committing.

Sorry, I misunderstood/misread the question. If the message is rejected the client will be notified of the error and the session will be closed. If you are publishing asynchronously, there will be a slight delay between you sending the message in the client and the client library then detecting that the session has been closed. > Producer has set the delivery property to PERSISTENT, I used --store-dir > to start the broker but I'm not sure if that means the queue is > persistent. Also the producer and broker are using direct exchange. Are you creating the queue through the c++ client also (if so then adding arg::durable=true to the call to queueDeclare() will make the queue durable)? Or through some other means (e.g. qpid-config, in which case specify --durable when creating the queue)? --------------------------------------------------------------------- Apache Qpid - AMQP Messaging Implementation Project: http://qpid.apache.org Use/Interact: mailto:[email protected] The information contained in this email is strictly confidential and for the use of the addressee only, unless otherwise indicated.
