@Omega359 Ah, that does make sense. So, if I understand correctly, the primary pain point is that you can wind up in situations where you've got two dataframes with the same logical schema, but different physical representations (e.g. `Utf8` v `Uft8View`), preventing them from being unioned together without some explicit casts? I think this points to a more fundamental tension between physical and logical types I think is worth addressing in a higher-level discussion. I'll have a look around to see if the topic has come up before. -- This is an automated message from the Apache Git Service.
