Hi @kumarUjjawal , i don't know if i am write but as per @comphead's comment >The gap: There is no reference doc that lists and describes what each built-in rule actually does. The codebase has 27 logical optimizer rules (e.g., push_down_filter, eliminate_cross_join, common_subexpr_eliminate) and 21 physical optimizer rules (e.g., join_selection, enforce_sorting, topk_aggregation), but the only way to learn what each one does is to read the source or use EXPLAIN VERBOSE. i think what we really need is an end to end doc that describe all 21 optimizer both type , could you look into this ? -- This is an automated message from the Apache Git Service.
