Does NATS support (or plan to support) log compaction? Without that, it's very hard to replace Kafka.

I"m not sure I understand your question; NATS streaming server (built on top of NATS) supports persistence to disk, a raft group, a SQL table, etc. and it appears the various storage implementations have mechanisms [0] to delete or compress old data.

That being said, I don't think this is what differentiates the two systems, the guarantees they do/don't make are likely what will make the decision for your project.

Yes, jetstream allows setting max messages to 1 in a stream.
