Aljoscha Krettek commented on FLINK-947:
----------------------------------------

Should we implement this on tuples for now? Without having some specialized underlying data structures.

> This would create an API that is a mix between SQL like declarativity and the power of user defined functions. Example user code could look like this:
> {code:Java}
> NamedDataSet one = ...
> NamedDataSet two = ...
> NamedDataSet result = one.join(two).where("key").equalTo("otherKey")
>   .project("a", "b", "c")
>   .map( (UserTypeIn in) -> return new UserTypeOut(...) )
>   .print();
> {code}
