Description

Users should be able to pass in a set of fields they wish to decode from Avro and the converter should avoid creating Vectors in the returned ArrowSchemaRoot.  This would ideally support nested columns so if there was:

 

Struct A

{     int B;     int C; }

 

 

The use could choose to only read A.B or A.C or both.
