### Search before asking - [x] I had searched in the [issues](https://github.com/apache/skywalking/issues?q=is%3Aissue) and found no similar feature requirement. ### Description ### Description This issue aims to address the refactoring of the TopN aggregation result query process to improve the efficiency and accuracy of aggregations. ### Tasks 1. **Custom Version Control**: Refactor the Measure's last-win version control to a custom version control. This new system should allow for different query types to utilize their respective version controls. While most measures will continue to use last-win, we need to implement a custom merge strategy specifically for TopN relevant measures. 2. **Merging TopN Lists**: Modify the query and merge process to ensure that TopN lists are merged correctly. - Compare the version of each data point sharing the same key. - Retain the most recent value based on the version. - Generate the final list based on filtered data points. 4. **Two Layer Merge**: The local and distributed query processor both perform the merging process. 3. **Result List Optimization**: Remove the node ID from the entity of the result list to streamline the data structure. ### Use case _No response_ ### Related issues _No response_ ### Are you willing to submit a pull request to implement this on your own? - [ ] Yes I am willing to submit a pull request on my own! ### 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.
