------------------------------------

             Summary: Introduce vectorized orc InputFormat for blink runtime
                 Key: FLINK-14135
                 URL: https://issues.apache.org/jira/browse/FLINK-14135
             Project: Flink
          Issue Type: Sub-task
          Components: Connectors / ORC
            Reporter: Jingsong Lee


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.
