-------------------------------------
> So the Dataset gets created with ParquetFragmentScanOptions (or whatever
> format)
Does it? I mean, this sounds like a good idea, and I like it. But do we
specify scan options when creating a dataset?
> [R][C++] PreBuffer is not enabled when scanning parquet via exec nodes

> 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.
