### 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 Now in sort node, we first do partial sort to get several sorted blocks and then do merge sort to get the final result. For partial sort, we use heap sort or pdq sort which uses a row-based comparison to sort. However, this row-based comparison is not efficient enough. ### Solution Use a column-based comparison is better, for multiple columns comparison , we do partial sort column by column ### 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.
