   @raoraoxiong Hey, thanks for the update. Regarding to the latest PR, it addresses two problems, for problem: `Top-level projection duplicates: identical deterministic calls in the projection (e.g. SELECT udf(a), udf(a)) are sent to the Python worker only once; a codegen expansion projection maps the deduplicated results back to the original output schema.
   ` have you considered addressing it in the planner?
