> And if that all makes sense... how do we do those optimizations? Is it something like an optimizer that has to downcast match on the expressions, or do we add methods to PhysicalExpr for each expression to describe how it handles this behavior? This is likely only applied to parquet filter so we can rewrite the filter when we know the filter + file_schema + table_schema (probably `build_row_filter`). We don't need optimize rule or trait method unless this rule could be applied more generally. -- This is an automated message from the Apache Git Service.
