Description

  1. Why does the RPC request not decrease?
    Because Pipe cannot detect the modification of the DataBase name, the modification of the DataBase name will bring about the modification of the scope of Pipe operation
  2. Why does it need to be deeply copied every time a request is sent?
    Because the PipeInfo in CN cannot be modified, PipeInfo is the last guarantee of Pipe synchronization
