   @sijie 
   
   It's hard to handle sequence id in key based batcher, if user set an external sequence id, we can't rewrite it and the sequence ids will distributed into inner batchers of key based batcher.
   
   Current implementation will throw exception if client can ensure the message is duplicated, since we do not throws exceptions before, is it ok to throws exception?
