Cleanup of Unused Queues
In an use-case like an mqtt client connects with CleanStart: No and Durable: Yes, the queue will be created and msgs are consumed as per the subscriptions. But when we restart the client, with a different session name will lead to creation of new queue. Now, both the old and new queues will have the same subscriptions.…

TTLs & Message Processing
Dear Experts, I am trying to use JCSMP client and I have three questions w.r.t message processing at client side and TTL : I have realised that if a message expires just at the moment it is being listened to at the client side, the message would be processed by client and also re-delivered via DMQ (as I am listening to DMQ…

Retry mechanism with delay
We are adapting our services to use Solace, and one of our applications uses a retry mechanism with delay from RabbitMQ in which an error message would be sent to a DLQ, which had a TTL configuration and, after the TTL expiration, it would be sent back to the initial queue. Beyond that, the message had a specific header…

Is it applicable to turn on/off Respect TTL settings in queue via API (using C#)

We have a publisher publishing messages to topics which are then spooled in a durable queue [endpoint] for guaranteed delivery, with several topic subscriptions for various subscribers. In our tests, the subscriber application acknowledgements do not seem to have any effect on the messages persisted in the queue; only a…

How to set Message TTL when using Spring Cloud Stream Binder Solace
Hi there, I am wondering whether it is possible to set a Message's TTL if you are on the Spring Cloud Stream layer. I wrote a message listener using Spring Cloud Stream, and at most I get access to a GenericMessage from the Spring Cloud Stream framework - but that class does not offer any methods to set a TTL. Is there any…

Max TTL for DMQs
I just bumped into this issue. We are replacing ActiveMQ with Solace for multiple customers so we somehow must implement this. It appears that Solace does not support this, see https://docs.solace.com/Configuring-and-Managing/Configuring-Queues.htm#Configur21. Is there any workaround for this? We want to automatically…
