@kevinjqliu - I've given this a bit more thought, and if we are looking to use `.` to represent nested fields, we will always run into an issue with `.` named fields if we split based on the delimiter. Unfortunately, I think this means that the scale of this problem is larger than a simple bug fix onto the `Expression parser`, `expression_to_pyarrow` and the `Reference` classes. I think we first have to come up with a proposal for representing nested fields in a flat string that doesn't result in these edge cases, or is at least configurable (e.g. Config parameter PYICEBERG__NESTED_FIELD_DELIMITER defined at the session level that defaults to `.`) -- This is an automated message from the Apache Git Service.
