Duplicates Topics Confirmation

[AayushSaini101]

Does RocketMQ allow to create of duplicate topics? I guess not. Whenever we create topics of the same name we get a message that is given below.
create topic to 192.168.1.8:10911 success.

• Can we use different messages like the topic is already present and cannot create the same name? or a confirmation of whether to create or topic or not? It would help to protect the older topic.

If it is possible I am willing to work on this issue and create the same.

At present, the MQAdmin cli tools only offer the updateTopic command. However, we could improve this by dividing it into two separate commands: createTopic and updateTopic. The former allow users to create a new topic, while the latter only make changes to an already existing topic.
