Implementing bulk export to Parquet

Hi, the project which I'm involved in would require us to integrate MonetDB with "big data technologies" so exporting data from MonetDB to Parquet for further processing in the big data tools would be an obvious choice. Can anyone guide me what it would mean to extend MonetDB with a writer for Parquet? It would be awesome if COPY INTO would be able to produce Parquet efficiently, e.g. using Arrow library: https://arrow.apache.org/docs/cpp/parquet.html Kind regards, Daniel
