Consumer-Initiated Transactions with multiple ProducerFactories, possible?

[jonas-grgt]

I have a use case where I want to, transactionally, consume a message and publish multiple events using different KafkaTemplate instances because they publish in different formats and hence have different serializers.

As far as I can tell, I believe this is not supported because a consumer-initiated transaction is tied to only one transaction-aware ProducerFactory and as such KafkaTemplate.

Is this correct? Is there a way to make this case transactional?
