> VectorizedParquetInputFormat is introduced to read parquet data in batches.
> When returning each row of data, instead of actually retrieving each field, we use BaseRow's abstraction to return a Columnar Row-like view.
> This will greatly improve the downstream filtered scenarios, so that there is no need to access redundant fields on the filtered data.
