> ---------------------------------------------------------------------------
>
> Key: ARROW-6592
> URL: https://issues.apache.org/jira/browse/ARROW-6592
> Project: Apache Arrow
> Issue Type: Sub-task
> Components: Java
> Reporter: Micah Kornfield
> Assignee: Ji Liu
> Priority: Major
> Labels: avro
>
> 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.
