---------------------------------------
[~lzljs3620320]
I want to leverage existing
org.apache.hadoop.hive.ql.io.parquet.vector.VectorizedPrimitiveColumnReader. So
ParquetColumnarRowSplitReader will need a wrap on hive column vector as ORC.
Not sure what's the efficient way of reading data directly to Flink Vector.

> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / Runtime
> Reporter: Jingsong Lee
> Assignee: Zhenqiu Huang
> Priority: Major
> Fix For: 1.11.0

>
> 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.
