support for parquet files

[alperyilmaz]

This might sound crazy but still I wanted to propose a feature request about parquet files.

You might ask, why? Parquet files are becoming more widespread and might even be considered as "the new csv". There are specialized tools such as duckdb to run sql commands on them. I didn't see or came across any awk-like utility which can process parquet files.

IMHO, supporting parquet files by frawk will be a huge win for "data analysis at the commandline" camp.
