Consumer group messages not unique

I’m running a three-node Kafka cluster. If I start the console consumer script on two nodes, both consumers receive messages even though they are in the same consumer group. Is this normal?

Hi @briank , Are they both receiving the same messages (i.e. messages with the same key?) If so - that’s not normal.

Each Consumer in a group receives messages from different partition, ensuring that only once consumer sees any particular message.
