---------------------------------------

             Summary: KeySelector can't implement ResultTypeQueryable
                 Key: FLINK-1227
                 URL: https://issues.apache.org/jira/browse/FLINK-1227
             Project: Flink
          Issue Type: Improvement
          Components: Java API
    Affects Versions: 0.7.0-incubating
            Reporter: Chesnay Schepler
            Assignee: Chesnay Schepler
            Priority: Trivial


The TypeExtractor currently doesn't check whether a KeySelector implements the ResultTypeQueryable interface.

Since i expected it to work i guess you can call ti a clarity issue. Additionally, this change will allow me to use KeySelector for the Python API.
