> Now the C++ reader and writer use LongVectorBatch for BYTE, SHORT, INT and LONG types and DoubleVectorBatch for FLOAT and DOUBLE types. Then it is user's responsibility to guarantee no overflow happens. It would be great if we can support type-specific ColumnVectorBatch for these types. As this is a public-facing API, we may provide  WriterOptions and ReaderOptions to enable it explicitly and turn in off by default.
