Werner Daehn commented on AVRO-2402:
------------------------------------

I have created a separate, small library for this, available via Maven Central.

> (This is now the second project where I needed a functionality like this in Avro. Hence I would greatly appreciate it if you can add that to the 1.10.0 release. I took extra care to make it simple and without any side effects.)
>  
> Imagine you are within the GenericRecord Employee->Addresses. You have all fields of the Addresses Schema of course but what if you need to read something from the parent, the employee record? 
> You would need to remember the entire parent tree, which is fine if you are just one level deep but can be cumbersome when the structure is 10 levels deep.
> I'd like the GenericData.Record and Array to contain the method
>  * getParent()
> as well.
> With that you can easily walk the nested tree of a deeply nested Schema up and now down as well.
