      Description

      Parquet ColumnarRow split reader 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.
