Python thrift rpc TProcessPoolServer 原生的多进程服务模式

以前通过多线程每个线程中再启进程的模式实现了多进程的服务模式。
今天发现其实进程池的模型是自带的。
这个Server在一个单独的文件中，与其它Server不在一起，不看代码不太容易发现。

示例代码

import sys, glob  sys.path.append('./gen-py')from WormHoleRPCService import WormHoleRPCService from WormHoleRPCService.ttypes import *  from thrift.transport import TSocket  from thrift.transport import TTransport  from thrift.protocol import TBinaryProtocol  from thrift.server import TProcessPoolServer  from time import sleepimport multiprocessingdef work_hi(pipe) :    passdef work_add(pipe ,  a , b) :    passdef work_getMap(a) :    passdef work_getList(a , b , c , d) :    pass    i = 0    while True :        i += 1 ;        if i > 30000000 :            break    res = [{a : 'tom' , b:'jim'} , {c : 'john' , d:'kobe'} ]    return resclass WormHoleRPCServiceHandler:    def __init__(self):      self.log = {}    def hi(self):      print 'hi'  def add(self , a , b) :    return a + b   def getList(self , a , b , c , d) :    return work_getList(a , b , c , d)  def getMap(self , a ) :    return arpc_handler = WormHoleRPCServiceHandler()  processor = WormHoleRPCService.Processor(rpc_handler)  transport = TSocket.TServerSocket(port=9090)  tfactory = TTransport.TBufferedTransportFactory()  pfactory = TBinaryProtocol.TBinaryProtocolFactory()  # You could do one of these for a multithreaded server  server = TProcessPoolServer.TProcessPoolServer(processor, transport, tfactory, pfactory)  print 'Starting the server...'  server.setNumWorkers(5)server.serve()  print 'done.'
