------------------------------------
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.
