Jetstream (includes Streams (better as in Kafka IMO), a powerful KV Store and also an Object Store to store files) is really powerful. It earns much more attention than it currently has.
Jetstream is also much easier to operate than Kafka IMO. Just a simple single binary with an easy to understand config.
