[jira] [Created] (ARROW-6593) [Java] Experiment with performance difference of avoiding the use of Avro Decoder

Micah Kornfield created ARROW-6593:
--------------------------------------

             Summary: [Java] Experiment with performance difference of avoiding the use of Avro Decoder
                 Key: ARROW-6593
                 URL: https://issues.apache.org/jira/browse/ARROW-6593
             Project: Apache Arrow
          Issue Type: Sub-task
          Components: Java
            Reporter: Micah Kornfield


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.
