This might be handled using GenericData. You'd specify no reader schema when you create your GenericDatumReader so the in-memory data is represented using the same schema it was written with. Then use GenericRecord#put & get to access the fields you require.
http://avro.apache.org/docs/current/api/java/org/apache/avro/generic/GenericRecord.html Might that work?
