Subject [GitHub] flink pull request: Enhance Partitioned State and use it in Window...

    Okay, that sounds like a design flaw in hiding the aggregating functions completely from
the window operator in the state. I think the operator should be aware of the additional function,
if only to open()/close() it.
    
    The fact that a RichReduceFunction cannot be used at all seems like a huge limitation.
