> # Implicit assumptions in LogicalPlans > Another thing that was mentioned was the challenge of writing custom optimizer rules was challenging because there were implicit assumptions (e.g. that column names were unique) There is more to it. We touched about this on last community call. in SQL the output column names don't have to be unique, so we should lift this limitation for the output (https://github.com/apache/datafusion/issues/13476, https://github.com/apache/datafusion/issues/6543). Proper fixing this requires changes how plans are constructed and represented (https://github.com/apache/datafusion/pull/13489#issuecomment-2488695180, https://github.com/apache/datafusion/issues/12723) -- This is an automated message from the Apache Git Service.
