> Parquet files are very opaque, and it'd be handy to have an easy way to introspect them. Functions exist for loading them as a table, but information about row group level metadata and data page compression is hidden. Ideally, every structure from https://github.com/apache/parquet-format/#file-format could be examined in this fashion.
