Subject [jira] [Commented] (FLINK-947) Add support for "Named Datasets"
Date Wed, 18 Jun 2014 12:40:02 GMT

    [ https://issues.apache.org/jira/browse/FLINK-947?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14035645#comment-14035645

Robert Metzger commented on FLINK-947:
--------------------------------------

This looks very good.
I would suggest to do a short-cut for String-arrays with only one argument to avoid the ugly
new String[]{} statement.

How does this issue relate to https://issues.apache.org/jira/browse/FLINK-908 ? Can we close
FLINK-908 here?

> 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}
