Creating a Kafka Consumer Group

Create a consumer group on the console.

auto.create.groups.enable: a consumer group is automatically created when a consumer attempts to enter a group that does not exist.

  • If auto.create.groups.enable is set to true, the consumer group status is EMPTY, and no offset has been submitted, the system automatically deletes the consumer group 10 minutes later.
  • If auto.create.groups.enable is set to false, the system does not automatically delete consumer groups. You can manually delete them.
  • If a consumer group has never committed an offset, the group will be deleted after the Kafka instance restarts.
  • Creating a consumer group on the console does not require instance restart.
