### 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 Currently, metrics from OAP and TopN generated from source metrics are both stored as a `Measure`. However, they are using different paths to read the data from the storage due to some historical reasons. Measure query is more complicated and comprehensive while TopN query is somehow ad-hoc. Then after finishing TopN streaming modules, we decide it is a good timing to fully unify the query planner and executor for Measure and TopN. ### Use case _No response_ ### Related issues _No response_ ### Are you willing to submit a PR? - [ ] 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.
