Could you please share more details about the “fatal error” you > mentioned during node startup? You are correct. I misread the code. I'll update the KIP to indicate that Kafka will delete the bootstrap checkpoint if it has been replicated to the cluster metadata partition. This may be tricky to implement correctly and efficiently. I am going to suggest that the bootstrap checkpoint will be deleted if a checkpoint has been loaded that is non-empty. > chia_3: If Kafka ≥ 4.2 creates bootstrap.checkpoint, users will see > deprecation warnings when starting Kafka because the file exists, correct? I think we can skip this based on your observation above. The node will simply delete the bootstrap checkpoint when it is safe to do that. Thanks, -- -José
