>
> In ExecNode_Scan a ScanOptions object is built up. If we are reading parquet
> we should enable pre-buffering. This is done by creating a
> ParquetFragmentScanOptions object and enabling pre-buffering.
> Alternatively, we could just default pre-buffering to true for asynchronous
> scans of parquet data.
