Hi Qpid Users, I have a use case where I need to ensure SLA guarantees based on dequeue latency for different message class. Each message has a specific time-to-live (TTL), and must be dequeued before it expires to meet its SLA.
While I’m aware that Qpid Broker-J supports priority queues, the priorities in this case are static and don’t directly help with the dynamic nature of my use case, where the expiration time for each message is different. The challenge is to ensure that messages are dequeued before their TTL expires, based on their urgency (i.e., how close they are to their expiration time). Could you suggest an approach or a mechanism within Qpid Broker-J to achieve the following: 1. Dynamically prioritize messages based on how close they are to their expiration time, so that messages nearing expiration are dequeued first. 2. Ensure messages are dequeued within the SLA window, before their TTL expires. 3. Handle the scenario where ongoing inserts with different TTLs are continuously added to the queue, and ensure that the system adjusts dynamically to the varying expiration times. Are there any features or strategies in Qpid Broker-J that would help in implementing this dynamic priority system, considering the TTL-based expiration for messages? Regards, Vinita Meka
