Kafka is attempting to address this with KIP-939: Support Participation in 2PC. In short, with KIP-939 it is now possible to declare that a transactional Kafka producer is participating in an externally-coordinated 2PC transaction. Effectively, this means Kafka acknowledges that an external transaction coordinator exists and has have full control in deciding transaction fate; Kafka will no longer proactively abort transactions from the 2PC-participating producer based on timeout, and will also allow resuming previous transactions so that the external coordinator has the final say in whether to commit or abort it. For a more detailed summary of KIP-939, please see KIP-939 Public Interface Summary.
