    Looks good except for the one remark I had.
    
    Did you run any performance tests on this? What is the overhead of using an Avro POJO
vs. a plain POJO vs. using the Kryo Serializer?

> Currently, the {{GenericTypeInfo}} registers the class of the type at Kryo. In order
to get the best performance, it should recursively walk the classes and make sure that it
registered all contained subtypes.
