Hi! I have two questions related to transactional producers:
1. Is it OK to mix transactional and non-transactional approach with a single KafkaProducer instance? I mean sometimes I want to publish multiple messages transactionally, but oftentimes just a single message. Starting a transaction for publishing a single message looks inefficient. What is the recommend approach here? 2. If I publish multiple messages to multiple partitions in a single transaction is it guaranteed to be all or nothing published? Is it possible to end up with only half of the messages published to half of partitions in some failure scenario? Sergi
