| hang onto a tuple and process it later (for instance, to do an aggregation or join). |
| |
| <p>Tuples should be emitted using the OutputCollector provided through the prepare method. It is required that all input tuples are |
| acked or failed at some point using the OutputCollector. Otherwise, Storm will be unable to determine when tuples coming off the |
| spouts have been completed. |
