Even StreamNative is effectively abandoning Pulsar and going all-in on the Kafka protocol. I can see the theoretical benefits of Pulsar, but it just doesn’t seem to have the ecosystem momentum to compete with the Kafka juggernaut.

The advantages of Pulsar are very much practical, at least for us. Without it we would have to manage two separate messaging systems.

I don't see any evidence of StreamNative abandoning Pulsar at this point. I do see a compatibility layer for the Kafka protocol. That's fine.

It sure looks like they’re going quite a ways beyond Kafka-on-Pulsar - the Ursa/Oxia work they’re focused on right now replaces BookKeeper and seems very firmly Kafka-oriented. Or does Ursa also work with the Pulsar protocol?

Ursa supports Pulsar protocol as well
