 <div class="block">Emits a new tuple to the default output stream with the given message ID. When Storm detects that this tuple has been fully
  processed, or has failed to be fully processed, the spout will receive an ack or fail callback respectively with the messageId as
  long as the messageId was not null. If the messageId was null, Storm will not track the tuple and no callback will be received. Note
  that Storm's event logging functionality will only work if the messageId is serializable via Kryo or the Serializable interface. The
  emitted values must be immutable.</div>
