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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
