By default, the consumer group count in an ApsaraMQ for Kafka instance is twice the count of partitions. For example, if an instance has 1,000 partitions, you can create up to 2,000 consumer groups in the instance. If you want to create more consumer groups in your instance, you can upgrade your instance specification. One additional partition allows you to create two more consumer groups. For more information, see Upgrade instance specifications.
