> 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.
