> Create a ColumnarBatch with ArrowColumnVectors for row based iteration
> ----------------------------------------------------------------------
>
> Key: SPARK-21583
> URL: https://issues.apache.org/jira/browse/SPARK-21583
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.3.0
> Reporter: Bryan Cutler
> Assignee: Bryan Cutler
> Fix For: 2.3.0
>
>
> The existing {{ArrowColumnVector}} creates a read-only vector of Arrow data.
> It would be useful to be able to create a {{ColumnarBatch}} to allow row
> based iteration over multiple {{ArrowColumnVectors}}. This would avoid extra
> copying to translate column elements into rows and be more efficient memory
> usage while increasing performance.
