We don't just apply DPP to any column, right? Shouldn't we check that the inferred filter is applied on partition columns? In that sense we should fix the DPP rule for it to be apply the same dimension table filter on partition columns from different tables. In other words, the DPP rule itself should generate a filter on `fact_stats.store_id` and another on `code_stats.store_id`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
