I am also very curious to know more. I’m sure the NATS maintainers are as well. Their architecture is extremely intuitive and appealing to me, so I wonder where things went south. Nats has a lot of tunable parameters with Jetstream. For instance, an in-memory stream with a time-based duplicate detection window, both push and pull semantics, and configurable re-delivery and ack policies. The one thing where I can see an impedance mismatch is ephemeral single-message connections which I don’t think it’s built for. In either case, more details would be invaluable.
