Did you check this?

https://docs.nats.io/nats-streaming-concepts/intro

"..Message/event persistence - NATS Streaming offers configurable message persistence: in-memory, flat files or database. The storage subsystem uses a public interface that allows contributors to develop their own custom implementations."

and

"At-least-once-delivery - NATS Streaming offers message acknowledgements between publisher and server (for publish operations) and between subscriber and server (to confirm message delivery). Messages are persisted by the server in memory or secondary storage (or other external storage) and will be redelivered to eligible subscribing clients as needed."

Also check out Liftbridge (https://liftbridge.io), which is a Kafka-like API on top of NATS.

I looked at Liftbridge when choosing a streaming platform for event sourcing, but the FAQ says it's not production ready. Is that still accurate?

No, i missed that. I think ive seen 'nats streaming', but didn't realize that it is its own distinct thing. All this makes more sense now to me, thanks!
