chenlinzhong opened a new pull request, #16639:
URL: https://github.com/apache/doris/pull/16639

   # Proposed changes
   
   Issue Number: close #16634 
   
   ## Problem summary
   
   mainly include:
   1. brpc service adds two types of thread pools. The number of "light" and 
"heavy" thread pools is different
   2. Classify the interfaces of be. Those related to data transmission are 
classified as heavy interfaces and others as light interfaces
   3. Add some monitoring to the thread pool, including the queue size and the 
number of active threads. Use these indicators to guide the configuration of 
the number of threads
   
   主要包括
   - 1.brpc服务增加2类线程池，"轻","重"  不同线程池的数量配置不一样
   - 2.对be的接口进行分类，跟数据传输有关的归类为重接口，其他为轻接口
   - 3.增加一些监控，包括be每个接口qps和线程池队列大小、活跃线程个数，根据这些指标来指导线程数的配置
