> Avro includes built-in deep-copying for specific and generic records, and 
> this deep-copying isn't based on serialization, which provides quite a bit 
> improvement in performance in some cases.
> We should make use of the built-in deep copying functionality from avro 
> instead of the custom serialization-based code that is currently in place.
