### 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 WideTable is commonly used in OLAP scenarios, which always result in many Null Columns. As a result, skipping batches of null data during computation is a natural optimization in MPP systems. Since there is already a NullMap in class `ColumnNullable` to indicate whether value in specific position is null or not, we can use that to bring into SIMD optimization to skip batches of null data. Further more, we could automatically do such optimizations based in CBO in the future. ### Solution _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
