I have not read the code base thoroughly, but I remember something like when I skimmed through it: this may be related to the fact that AFAIK we currently clone the file reader for every new seek. Thus, even for a single file, we usually open that file multiple times, once per seek (which is roughly one per `row group` and per `column chunk` plus one, to read the metadata). -- This is an automated message from the Apache Git Service.
