How is the performance, how good does it scale horizontal/vertical?

Could it be used as a replacement to Kafka message queue/ring?

Have you taken a look at nats? (https://nats.io/)

Otherwise, the cloud native landscape has some similar projects listed in the same category as kafka: https://github.com/cncf/landscape
