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.
