   ### 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
   
   In the MVP of BanyanDB, all rows would be overrides when the latest data was inserted with the same ID.
   In advanced, it is better BanyanDB could provide a function based merging mechanism to merge previous and new data. Based on this, SkyWalking OAP `L1->L2` distributed aggregation would not be necessary, and also would not require **reading metrics from DB before flushing back**, **maintaining session**.
   
   ### Use case
   
   This would highly advanced feature, which should not be considered in the first release. In longer-term, this would show much better performance as a native database.
