> Hi, @xinyiZzz > Is there an issue describing the specific problem? > The previous version of Doris had problems when handling Null partition columns, and the current code should have been fixed. > If you want to prohibit the Partition column from being null, you need to discuss it in the Issue or Mail list. The null value to be a partition value is very confusing. Currently, the null value is stored in the partition with MIN_VALUE lower bound. But if that partition is dropped, the null value can not be loaded. So it is not a good way to solve the problem. Some other database use a special partition to save null value. But I think it is very hard to maintain and hard to understand. Is it necessary to allow null value to be a partition value? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
