FakeProducer.produce does not require specifying partition but KafkaStore does

FakeProducer does not produce without specifiyng partition, but confluent-kafka does. Also why its an optional parameter if KafkaStore needs it anyway?

Hi @q0w ,
I think it uses partition 0 by default, or distributes messages in a round-robin fashion — is that correct?

I am not sure what confluent-kafka is doing under the hood
