   Agree. It doesn't make sense not to support earliest/latest... 
   
   > 2\. seeking by messageId is also doable. because messageId provides partition id.
   
   If the seek operation only affects the cursor in one partition, it might become confusing
to a user, since it's a different behavior from the above. 
   
   In general, I'm not a big fan of seek by message id on the consumer interface, since the
purpose of `Consumer` should be that the reading position is "managed" by the system. If an
application wants to position to a particular message id, it's more of manual handling and
maybe `Reader` is a better option there.
