## 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.
