[GitHub] [incubator-doris] JinLiOnline opened a new issue #5550: [BE] memtracker中parent和limit显示有歧义
JinLiOnline opened a new issue #5550:
URL: https://github.com/apache/incubator-doris/issues/5550
**Describe the bug**
doris version：0.14-rc3
BE_IP:BE_HOST/mem_tracker 可以看到详细信息
有些疑惑点，比如：
1）root节点limit为none
2）mem_limit 只限制了 ExecEnv Root
3）在代码中：比如 load channel mgr是根据 ExecEnv中的 mem_limit来计算的，但在上图中它的父节点是root，却不是ExecEnv root。
**Expected behavior**
我的理解，参数mem_limit限制be总的内存，作为root节点，be其他模块的可用内存上限，从root中继承。

Hi，3 questions：
1)：none means not limit, now Doris do not hava mem limit of root
2): some operation of Doris now do not limit the mem
3): load channel mgr is a Independent memory management module do not have relations withe ExecEnv. You can find the answer in the source code. To be honest, it's a bad name, we will change the name of it.
