I'm curious - can MQTT or some enhancement to it achieve persistence and exactly-once-delivery semantics (or at-least-once semantics) ? I am looking for a message queue with guaranteed delivery that can be embedded into existing platform and packaged with it (so that there is no external dependency for messaging, like Kafka, etc.).
I investigated NATS Streaming but found some information that discouraged me from using it.
