> 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.
