HappenLee opened a new issue #5515: URL: https://github.com/apache/incubator-doris/issues/5515
## Motivation At present, Doris MemTracker are very chaotic. There are a lot of memory occupation not recorded. As a result, many scenes can not accurately judge the memory usage, and quickly locate the real mem problem. So, we should now sort them out so that Doris' memory usage can be seen at a glance. ## Which Part Should be Register in MemTracker I used TCmalloc to analyze the memory allocation of Doris. I found that the following modules will occupy a lot of memory, but without effective memory monitoring, it will bring trouble to Doris. * **DataLoad** * **StoragePageCache** * **SchemaChange** * **Compaction**: Both auto compaction and manual compaction * **TabletManager** ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
