Github user ravipesala commented on the issue: https://github.com/apache/carbondata/pull/3025 @qiuchenjian currently pre-aggregate datamap is not following the datamap interfaces as it was implemented before datamap framework. That is why not all datamap DDL works with pre-aggregate. It is better to keep the pre-aggregate datamap untouched in this area until we decide whether to take MV datamap or pre-aggregate datamap.
