Re: Qpid destroys session after max queue size reached

Gordon If I have the Sender Capacity to 1000 Messages per example, and the queue has a limit of 800 Messages, and after I send 801 messages, the session is closed after the exception while trying to delivery the message to the queue. But the 800 messages sent previously are guaranteed to be

For my safe, since my app is multithreaded, the best I can do is to serialize access to the same Sender/Session object on each send() call and check for errors to try to handle such situation. On Thu, Mar 22, 2012 at 14:32, Gordon Sim g...@redhat.com wrote: On 03/22/2012 04:58 PM, Virgilio

Re: Overhead of creating (private reply) queue?

We used here to create a private reply queue for each request/reply (and also, we discovered leaks with Ted Ross in 0.10 version that time). After that, we changed our code to pre-create a private reply queue for each connection that perform request / reply operations, using message.

You probably need msgpack, protobuf (and others) are what you need to look at. Also, think in amqp as a 'low-level message transport layer', msgpack (or another) as 'low-level message codec layer' and develop your app without knowing how the things are done 'under the hood'. On Fri, Jan 10, 2020
