org.apache.samza.system.IncomingMessageEnvelope
This class represents a message envelope that is received by a StreamTask for each message that is received from a partition of a specific input stream.

      List<IncomingMessageEnvelope> outgoingList = new ArrayList<IncomingMessageEnvelope>(queue.size());


      if (queue.size() > 0) {
        queue.drainTo(outgoingList);
      } else if (timeout != 0) {
        IncomingMessageEnvelope envelope = null;


        // How long we can legally block (if timeout > 0)
        long timeRemaining = stopTime - clock.currentTimeMillis();


        if (timeout == SystemConsumer.BLOCK_ON_OUTSTANDING_MESSAGES) {

          Thread.sleep(brokerSleepMs);


          // Add messages to the BlockingEnvelopeMap.
          for (SystemStreamPartition ssp : sspsToFetch) {
            for (int i = 0; i < messagesPerBatch; ++i) {
              put(ssp, new IncomingMessageEnvelope(ssp, "0", "key", "value"));
            }
          }
        }
      } catch (InterruptedException e) {
