Re: TCP, it only maintains sequencing guarantees over the lifetime of a single connection. Obviously this is too weak of a guarantee for Kafka as leaders can change in a cluster. We've built idempotence in a way that makes the sequence number and producer ID part of the Kafka log. So it can provide idempotence even if brokers fail and new connections are established between the producer and broker |
