The region ID of the resource.

ResourceId.N RepeatList Yes alikafka_post-cn-v0h1fgs2****

The ID of resource N from which the tag will be unbound. The resource ID follows these rules:

For example, the resources from which the tag will be unbound include the alikafka_post-cn-v0h1fgs2xxxx instance, the test-topic topic, and the test-consumer-group consumer group. In this case, their resource IDs are alikafka_post-cn-v0h1fgs2xxxx, Kafka_alikafka_post-cn-v0h1fgs2xxxx_test-topic, and Kafka_alikafka_post-cn-v0h1fgs2xxxx_test-consumer-group respectively.
