[GitHub] [incubator-doris] HappenLee opened a new issue #5782: [Enhance] Make MemTracker More Reasonable

HappenLee opened a new issue #5782:
URL: https://github.com/apache/incubator-doris/issues/5782


   **Describe the bug**
   
   ## 1 Make Some MemTracker have reasonable `Parent MemTracker` do not the `Root Tracker`
   ## 2 Make Each MemTracker can be trace:
           
   The current memory consumption is mainly concentrated on the following operations:
   
   - query
   - load
   - compaction
   - schema change
   
   But it's really difficult to Identify the memory consumption caused by that particular operation, such as three queries. We don't know which query occupies the most memory.
   
   So we need a way to identify it
   
   - query ：each memtracker of same instance the label have same instance id
   - load：same as above
   - compaction ： each memtracker of same tablet of compaction the label have same tablet id
   - schema change： each memtracker of same tablet of schema change the label have old tablet id - new tablet id
   
   
   ## 3 Add `show level` of MemTracker to reduce the `MemTracker` show in the web page to have a way to control show how many tracker in Web page.
