      void close()  
      void flush()
      Flush all the pending acks and send them to the broker.
      void flushAndClean()  
      boolean isDuplicate​(org.apache.pulsar.client.api.MessageId messageId)
      Since the ack are delayed, we need to do some best-effort duplicate check to discard messages that are being resent after a disconnection and for which the user has already sent an acknowledgement.
