> Parquet writers like delta-rs rely on the Parquet metadata to write
> file-level statistics for file pruning purposes.
> We currently do not expose these stats, requiring the writer to read the file
> that has just been written, to get the stats. This is more problematic for
> in-memory sinks, as there is currently no way of getting the metadata from
> the sink before it's persisted.
> Explore if we can expose these stats to the writer, to make the above easier.
