### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues. ### Description Currently, OLAP table in nereids planner only supports the duplicated data model. Aggregate and Unique data models are not supported. This issue is for supporting aggregate and unique data models and support rollup and materialized view selection. Subtasks for the issue: - [x] Main framework for selecting rollup index with aggregate plan node, pre-aggregation for OLAP scan is turned on by default. #12464 - [x] Support turning off pre-aggregation for OLAP scan table, e.g., select data without aggregate plan node, select by non-matching aggregate function type, etc. #12785 - [ ] Support all the aggregate column types in the storage engine, such as bitmap, HLL, etc. - [ ] Support complex expressions in an aggregate function that could use pre-aggregation. - [x] Support materialized view selection for the duplicated data model. https://github.com/apache/doris/pull/13416 - [ ] Support merge-on-write of the unique key model in nereids planner.
