Hi, By quick looking at the codes, it looks like Arrow is depending on Parquet, however Parquet looks kinds of heavy for Arrow. Not sure what's the exact part in Parquet Arrow is using. Not sure if the vice versa is better or not, say in Parquet project, have a new reader that reads parquet data into an Arrow representation, let Parquet depend on Arrow instead. I noticed there was some effort (PARQUET-131) that reads parquet data into column vectors, wonder if it's the very similar thing needed for Arrow.
Will we support other formats like ORC file as well? If so, how to handle the relationship similarly? Thanks. Regards, Kai
