there has been some discussion online recently regarding Debian and the 
Parquet data format

   Are Parquet data drivers available in ordinary Debian repos ?

   Does GDAL build for #osgeolive include a Parquet data access driver ?

Pandas is in Debian but it cannot read parquet files itself, it uses 3rd 
party "engines" for that purpose and those are not available in Debian
