Hey, Is it possible to deploy Datahub without Kafka, using only the push Api model?

The MAE needs kafka though, so my guess is no.

Yes Kafka is a hard dependency (we will support other cloud pub-sub systems in the future). The reason is what Fredrik mentioned- we want to be able to take automated action on metadata changes

So, even though we don't want to use MAE and MCE, is Kafka a GMS dependency?
