Bryan Cutler updated SPARK-21583:
---------------------------------
Description: 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. (was: The existing
