This may be a hard one to pin down but I noticed that multiple schema migration steps executed sequentially in the same update_schema context sometimes result in Exceptions like column name not found when using Iceberg tables on AWS Glue. An example:
withtable.update_schema() asupdate:
update.rename_column("some_column", "renamed_column")
update.move_first("renamed_column") # this sometimes fails with an error# that renamed column doesn't exist
I have not noticed it with other back-ends like SQLite, leading me to believe it is a Glue issue specifically where a write may not yet be reflected by the time of the next operation.
