Fabian Hueske commented on FLINK-991:
-------------------------------------
I think the example is fine, but one or two sentences about when and how to use
the expression keys would be good.
What are the requirements. I guess the fields must be public or do you also
look for default getter methods?
> Add documentation for POJO expression keys
