Is 600 MB a lot for pandas? Of course, CSV isn't really optimal but I would've sworn pandas happily works with gigabytes of data.

What do you mean not optimal? This is quite literally the most popular format for any serious data handling and exchange. One byte per separator and newline is all you need. It is not compressed so allows you to stream as well. If you don't need tree structure it is massively better than others

But which separator is it, and which line ending? ASCII, UTF-8, UTF-16 or something else? What about quoting separators and line endings? Yes, there is an RFC, but a million programs were made before the RFC and won't change their ways now.

Also you can gzip CSV and still stream them.
