> Will it cover `multiple` nested scenes? The solution here seems to still bypass the child's lazy execution, right? Yes, it cover the `multiple` nested scenes. And yes the `children.evaluate` execute first, but we postpone the handling of Exceptions to ensure that the children's exceptions can be obtained during GenericUDF.eval. When facing multiple layers of GenericUDF, if the innermost child throws an exception, we also gradually execute the child GenericUDFs and handle the thrown exceptions layer by layer until the top layer. -- This is an automated message from the Apache Git Service.
