Good to see some documentation as well!
Which types are supported by the expression API? Only scala case-classes?
POJOs ? Even more?
Would be could if you could add that to the documentation.
> Add support for "Named Datasets"
> --------------------------------

> Key: FLINK-947
> URL: https://issues.apache.org/jira/browse/FLINK-947
> Project: Flink
> Issue Type: New Feature
> Components: Java API
> Reporter: Aljoscha Krettek
> Assignee: Aljoscha Krettek
> Priority: Minor
>
> 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}
