Hello. I'm not sure whether it's a bug or not, but here is a something wrong;
I set 2 consumer apps that have same consumer group id, and partition has been set to 1 on my Kafka Broker. In theory, the messages on the Kafka Broker must be consumed either one, which means it must not be consumed at both of them. But the messages were sometimes consumed to both of them. I found the definition of the partition at the Kafka Website: *"Kafka only provides a total order over messages within a partition, not between different partitions in a topic. Per-partition ordering combined with the ability to partition data by key is sufficient for most applications. However, if you require a total order over messages this can be achieved with a topic that has only one partition, though this will mean only one consumer process per consumer group."* What's wrong with my setting? Regards KIM
