> Key: FLINK-11899
> URL: https://issues.apache.org/jira/browse/FLINK-11899
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / Runtime
> Reporter: Jingsong Lee
> Assignee: Jingsong Lee
> Priority: Major
>
> VectorizedParquetInputFormat 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.
