Deletes a group ID.

Usage notes

You can call this operation when you need to recycle resources. For example, when applications are deleted, you need to recycle relevant resources.

After a group ID is deleted, the backend of Message Queue for Apache RocketMQ recycles resources of the group ID. This process is time-consuming. Therefore, we recommend that you do not create a group ID immediately after you delete one. If a group ID fails to be deleted, troubleshoot the issue based on the returned error code.

Note After you delete a group ID, the consumers identified by the group ID immediately stop receiving messages. Exercise caution when you call this operation.
