             Summary: 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


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
{{ArrowColumnVector}}s.  This would avoid extra copying to translate column elements into
rows and be more efficient memory usage while increasing performance.
