@cloud-fan the python side is blocked on how to build the expression protos: https://github.com/apache/spark/blob/master/python/pyspark/sql/connect/column.py Right now there is a mixed of `ColumnRef`, `str` as `UnresolvedAttribute`, etc. without a clear API for different cases. For example str could be `expression string` or `UnresolvedAttribute`, but current `column.py` only consider `UnresolvedAttribute` case. I am thinking how to refactor on python side to have the expression system to easy build expression proto. -- This is an automated message from the Apache Git Service.
