| EncRowCalcBolts send flush signals to the EncColMultBolts indicating that they have finished sending all tuples for a session. Whenever a flush signal is |
| received from a EncRowCalcBolt, the num of received flush signals is tallied until each EncRowCalcBolt has emitted a flush signal. |

| Once a flush signal has been received from each EncRowCalcBolt, all <code><columnIndex, aggregate colVal product></code> tuples are sent to the OutputBolt and a |
| session_end signal is sent back to each EncRowMultBolt. |

| The EncRowMultBolts buffer their output from the time that they send a flush signal to the EncColMultBolts until the time that they receive a session_end |
| signal from all of the EncColMultBolts.</div> |
