Yeah, I'm not sure about linq as well. I like the name but realise that it
might be problematic. What do the others think. I could call it
"flink-expressions".
I will add documentation about which types are supported and a good error
message for unsupported types as @rmetzger mentioned.
> 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}
