The way I see it, physical expressions are low-level enough that you would have to explicitly provide an alias. But I'm curious to know. In datafusion-comet, they heavily rely on physical layer stuffs. They directly build the physical expression with out logical expression. https://github.com/apache/datafusion/issues/11359 This is also the reason why logical expression confused them while it is unnecessary for them to build physical expression. -- This is an automated message from the Apache Git Service.
