> 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.
