Any list of valid attributes to use for mp.messaging.connector.smallrye-kafka?

[rsylthe]

I've been trying to find a list of valid attributes that can be used to configure the Kafka connector (mp.messaging.connector.smallrye-kafka.*), but none of the documentations from Quarkus, SmallRye or Eclipse actually mention exactly what is allowed and valid when configuring the connector.

Am I correct to assume that attributes that are shared between incoming and outgoing channel configurations are also valid on the connector level configuration? Or could even some attributes that are only applied to either one of the incoming/outgoing channels also be applied on the connector level configuration?
