You can call this operation to delete specified topics under your account.
This operation is called when resources are recycled, for example, when applications are deprecated. Resources must be recycled on the RocketMQ backend after a topic is deleted. This process takes time. Therefore, we recommend that you do not create a topic immediately after deleting one. If the deletion failed, take measures based on the error code that is returned. When calling this operation, pay attention to the following:
By default, only primary accounts can call this operation. RAM sub-accounts can call this operation only after being authorized.
If a topic is deleted, all published subscriptions under the topic are cleared. Therefore, call this operation cautiously.
