[jira] [Created] (FLINK-14135) Introduce vectorized orc InputFormat for blink runtime
Jingsong Lee created FLINK-14135:
------------------------------------
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.
