> This is an enhancement proposal for Stratosphere.
> It is possible to have multiple outputs for a given PACT, like the figure below illustrates:
>              (SRC)
>                |
>              REDUCE
>             /  |  \
>      +-----+   |   +-------+
>      |         |           |
>     (SINK A)   |        (SINK C)
>             (SINK B)
> All records are going to all sinks.
> It would be preferable sometimes to select a sink for a record .. For example each group into a separate file (yes, I know, one could add a filter before each sink)
> We could add another collect() method like this
>     public void collect(int sinkId, PactRecord record)
> The current collect() is quite simple:
>     public void collect(PactRecord record)
>     {
>         for (int i = 0; i < writers.length; i++) {
>             this.writers[i].emit(record);	
>         }
>     }
