Doug Cutting commented on AVRO-1268:
------------------------------------
The numbers (some faster, some slower) sound like they might be acceptable.
It'd sure be nice to not make anything significantly slower. I'm not clear why
you need the Map<Schema,Object> map. It seems to me that you should be able to
have the DatumReader hold the root of the state tree, but perhaps I'm missing
something. The tree might simply be either a leaf state or an array of trees,
one per field/union branch.
Can you post the patch?

> Stringable types are java classes that can be serialized through strings
> (which require a single string constructor and a valid toString()
> implementation). ReflectData currently has support from stringable types but
> it would be desirable to get this feature with SpecificData.
> The work involves changes to the SpecificCompiler (depends on {{@java-class}}
> support in AVRO-1267) to generate the specific sources with the proper java
> type as well as moving the ReflectDatumReader and ReflectDatumWriter to read
> the java-class/java-key-class and java-element-class properties.
