> For many functions (here for example KeySelectors), one can use lambda
> expressions:
> {code}
> DataStream<MyType> stream = ...;
> stream.keyBy( v -> v.getId() )
> {code}
> Java's other syntax for this, Method References, do not work:
> {code}
> DataStream<MyType> stream = ...;
> stream.keyBy( MyType::getId )
> {code}
