Description

VectorizedOrcInputFormat is introduced to read orc 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.
