> Starting from the stream of Items, we just need to key it by Color, as we
> want pairs of the same color. This will make sure that elements of the same
> color end up on the same physical machine.
> // key the shapes by color
> KeyedStream<Item, Color> colorPartitionedStream = shapeStream
> .keyBy(new KeySelector<Shape,
> Color>(){...});{noformat}
>
> However, it uses shape stream and KeySelector<Shape,Color> but should use
> KeySelector<Item,Color> to create KeyedStream<Item,Color>.
