> Components: Parquet
> Affects Versions: 8.0.1
> Reporter: xiangxiang Shen
> Priority: Major
>
> Improve parquet reading performance for String/Binary type based on Buffer
> operations instead of BinaryArrayBuilder.
>
> Currently, parquet String/Binary type reading performance is not good enough.
> For fixedwidth types, the Reader has adopted Buffer operations instead of
> ArrayBuilder interfaces.
>
> So it‘s better to use Buffer operations in String/Binary type reading.
