So there is base NATS and abstractions built upon NATS. Which are you referring to?

There's documentation on this bug/feature[0] and it looks like using NATS streaming is a way to fix this. I will admit that it's a bit annoying to figure out the difference between NATS streaming, jetstream and Liftbridge but I don't think this issue affects all 3. Jetstream is essentially NATS streaming built into the NATS binary itself, so switching to it should produce the feature set you're looking for.

NATS JetStream is very different, implementation-wise, from NATS Streaming. The latter is deprecated and no longer under development.

JetStream is impressive and looks very promising. I did some stress testing recently and found some performance issues and possible bugs, but I wouldn't hesitate to put it into production.

Completely agree with that. I was referring base NATS.

RabbitMQ plays in the field of traditional general purpose messaging system. NATS was specializing on performance. Kafka focused on streams. That is a focus and includes trade offs. Which is all fine. That is all I want to address.
