Note

• If you set a topic's consumer to autoscale (by using k8 or similar orchestrator), you must make sure that the max pod is no more than the amount of the topic's partition.

  • This is because of each topic's partition can only be assigned to one subscriber.

• It is okay for your consumer to be less than the topic's partition amount, because each consumer can handle multiple partitions from the same topic.
