   > +1. But I think we still need to deep into this issue: Why http heartbeat will timeout.
   
   @kangkaisen 
   netty use reactor model, some connection would be binded to one NioEventLoop thread, if some business logic wasting to much time, it will affect other requeset, and now doris process all business logic in io thread(NioEventLoop)
   
   some http url may cause slow reponse,  like /api/show_proc?path=/transactions/29327,  this url sometimes may get result slowly.
