maybe We can also reset the cursor based on message id.

actually the replay feature only works with a "timestamp". The main reason is that rolling back to a specific messageId would be impossible to do on a partitioned topic.

The application may provide messageIds for each partition, but timestamp already meets most of the replay cases in application, :-)
