             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.
