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

             Summary: Use Kryo for user code object serialization
                 Key: FLINK-1256
                 URL: https://issues.apache.org/jira/browse/FLINK-1256
             Project: Flink
          Issue Type: Improvement
            Reporter: Till Rohrmann


Currently, Flink uses java serialization for user code objects (UDFs). This limits the set of supported types which can be caught in the closure or are contained as members in the user code object. Maybe we can add Kryo as a second serialization mechanism which is used if the Java serialization fails. That way we would support more complex user code objects which finally improves the user experience.
